## MODEL "S" CARBURETER

### Used on Series 691 Nash Sixes

The carbureter measures the fuel charges for the engine and automatically mixes them with the proper amount of air to form a highly combustible gas. The Marvel Model "S" Carbureter is of the automatic air valve, heat controlled type. Its outstanding advantages are:

1. Simplicity of construction and operation.

2. Quick starting in any weather.

3. Automatically controlled heat application to ensure complete vaporization of fuels.

4. Economy in fuel consumption.

5. Ease of adjustment to meet varied driving and climatic conditions.

#### CONSTRUCTION

The construction embodies a main body or mixing chamber and a conventional float chamber bowl with fuel strainer attached at point of entrance of fuel to bowl. Within the mixing chamber are two nozzles which proportion the amount of gasoline used in the mixture. One of these nozzles, called the "low speed," is regulated by the gasoline adjustment screw at bottom of carbureter and the other, called the "high speed," is controlled by the automatic air valve. An air screw is provided which regulates the pressure of the air valve spring enclosed therein. Within this screw is also enclosed a plunger connected by a link to the air valve. The function of this plunger is to provide a resistance in addition to that of the air valve spring to assist in acceleration. This arrangement of plunger and air valve screw is termed the dash pot.

A further control of the high speed jet is provided by the fuel metering valve operated by the carbureter throttle. This valve provides the maximum fuel feed to the "high speed" nozzle when the throttle is fully opened for high speeds and for quick "pick up." During the ordinary driving ranges this valve controls the amount of fuel being used, thus providing all the economy possible. This valve is entirely automatic and requires no adjustment.

The passage-way from the mixing chamber to the intake manifold is controlled by a butterfly valve which is called the throttle-valve and is connected to the throttle-lever on the steering wheel as well as to the foot accelerator, its position determining the amount of gas and air or mixture being fed the engine.

#### STARTING

A choke button is provided on the instrument board to assist in starting. Pulling out this button closes a butterfly choker valve (see cut) in the air intake passage of carbureter which restricts the air opening of the carbureter, and consequently produces a richer mixture.

To start engine, pull out choke button all the way. Advance spark lever about half way and throttle lever about one-quarter way and depress starter pedal.

As soon as motor fires when starting, this control should be released part way, otherwise too much fuel will be drawn from carbureter, causing flooding of the motor and failure of the latter to continue to promptly fire. After starting, motor should be allowed to run "part choke" as stated for a few minutes while warming up, then the choker control should be fully released, or pushed in completely on the instrument board, and engine allowed to run normally for sometime until water in cylinder jackets is thoroughly warmed up before starting to make final carbureter adjustments.

#### HEAT CONTROL—STOVE

In the colder seasons warm air is fed to air intake of carbureter through the warm air elbow "F" (see cut). This elbow connects the carbureter with the warm air stove, which is a casting surrounding the two exhaust heat tubes which supply exhaust heat to the carbureter jackets as described below.

The amount of heat required for proper carburation depends on the temperature of the outside air. The first means of control is in the warm air stove just described, which should be connected to the carbureter furnishing warm air to carbureter air intake in all seasons of the year when the outside air temperature is below 50° F., whenever the outside air temperature runs above this point cold air should be furnished to carbureter air intake. This can be done by loosening the wing nut holding the warm air elbow "F" on the stove and also loosening the set screw holding this elbow in the air intake of carbureter, after which slide elbow out of air intake and revolve it—180 degrees about an horizontal axis and re-insert in carbureter air intake and lock in place with set screw. The opening in the elbow now is turned down away from the stove and draws in only cold air.

The above procedure, it must be understood, will vary somewhat due to differences in locality, altitude and fuels used, but it should be borne in mind that the best economy can be had with cold air passing to the carbureter, and the stove should not be connected until the acceleration and performance of the job requires the use of warm air for the best results.

The adjustment of the carbureter should be made per the above description of the stove, as the latter is used for meeting weather conditions and should be set as described.

#### HEAT CONTROL—CARBURETER JACKETS

The carbureter and manifolds have been designed to utilize the exhaust gases of the engine to insure complete vaporization and a consequent minimum consumption of fuel. This is accomplished by surrounding the upper portion of the mixing chamber with a large heat jacket provided with an inlet and an outlet opening and connected by means of tubes to an exhaust manifold valve body in the exhaust pipe of the engine; this valve body, housing a large valve called the main-exhaust-heat-valve ("C" in cut) within the body itself, the return or outlet tube from the carbureter heat jacket entering the valve-body in the lower portion below the main-exhaust-heat-valve.

The main-exhaust-heat-valve "C" is connected by means of a lever and long connecting rod to the throttle lever of the carbureter so that when the throttle valve is operated the main-exhaust-valve is operated simultaneously with it.

The purpose of the carbureter heat jacket and valve in exhaust line with connections described, is to provide means for utilizing the heat of the exhaust gases of the motor for vaporization of the fuel supplied the engine by the carbureter and to do so automatically. The automatic feature of same is accomplished by setting the Main-Exhaust-Heat-Valve "C" by means of the long connecting rod, in closed position with the closed or idling position of the throttle valve, thus providing for and causing all of the exhaust gases of the engine to pass through the heat jacket of the carbureter when engine is idling and to regulate the volume of this heat as throttle is opened by automatically opening the Main-Exhaust-Heat-Valve, thus allowing the increasing volume of the exhaust gases to pass on out through the main exhaust pipe without being deflected and by-passed to the carbureter heat-jacket as the motor speed increases.

HEAT SETTING No. 1

By referring to the cut shown (See Page 5) and noting "Heat Setting No. 1," it will be noted that valve "C" in main exhaust line is fully closed with the closed or idling position of the throttle valve. This adjustment is accomplished by having long connecting rod "R" from valve "C" Lever set in "Hole No. 1," in Throttle Lever "L," being sure that when throttle valve is standing in fully closed or idling position that valve "C" is also in closed position, proving out the latter feature by loosening connection of valve "C" lever holding long connecting rod; holding Throttle Lever "L" in closed or idling position and bringing up valve "C" lever on connecting rod "R" as far as it will go to the right toward the carbureter and tightening its connection on the connecting rod in that position. After having made the adjustment as just described, it is assured that "Heat Setting No. 1" has been properly made and that all of the heat possible from the exhaust has been secured.

This "Heat Setting No. 1," provides as stated, for the most exhaust heat obtainable and should be used during the entire year, except in extremely hot seasons or hot climates or when high-test gasoline is being used in engine and even then unless engine is losing power due to excessive heat.

If loss of power or mileage due to too much heat is experienced, first be sure that it is not due to driving on hot-air instead of cold-air. After making this observation, if there is still too much heat, refer to cut (See Page 7) describing "Heat Setting No. 2." It will be noted that connecting rod "R" from valve "C" is removed from "Hole No. 1," in Throttle Lever "L" and placed in "Hole No. 2," in Throttle Lever. This change is all that is necessary in order to reduce the amount of heat applied to carbureter. In "Heat Setting No. 2," when the throttle is in closed or idling position, valve "C" is quite aways off its seat. This adjustment provides for a great deal less heat than is provided by "Heat Setting No. 1" and is all that is required in the reduction of the volume of heat together with driving on "Cold" air for the main-air-supply, in the warmest weather or hottest climates.

HEAT SETTING No. 2

NOTE—After original position of valve "C" is made as described in "Heat Setting No. 1" do not again readjust valve "C" on connecting rod but when changing from "Heat Setting No. 1" to "Heat Setting No. 2," merely change position of long connecting rod from "Hole No. 1" to "Hole No. 2" in throttle lever.

#### ADJUSTMENT

No change should be made in the carbureter adjustments until after an inspection has been made to determine if the trouble is in some other unit. It should be noted that the gasoline lines are clear, that there is gasoline in the vacuum tank, that there are no leaks at connections between carbureter and engine, that the ignition system is in proper condition, and that there is even compression in all cylinders.

If it is necessary to test adjustment or to make a readjustment proceed as follows:

Set air screw so that the end is flush with the end of ratchet set spring. Loosen packing nut on needle adjustment. Turn gasoline adjustment to the right very carefully so as not to injure the needle point, until the valve is closed gently against its seat. Then turn to left approximately one complete turn which will bring notch in the disc handle directly below the guide post above it. Tighten packing nut to hold needle firmly as set.

The notch in disc handle of needle is put in handle after the needle has been carefully calibrated by a flow-meter at the factory, therefore the notch in handle should register with guide post above it. This setting of needle valve is absolutely essential to get the best results. The object in directing that needle be first turned to the right until closed is to insure against two or more turns open, as from closed position to notch (usually about one turn) is the normal setting. This being true it is not necessary to turn needle in to the right firmly but merely far enough to be sure that when turning back to the left, to the notch registering with guide post, that the needle is not more than once around or one turn from its seat.

Set stove heat and damper heat as previously instructed above. Pull out choker to closed position and start engine in usual manner. As soon as engine has fired release choker three-fourths of way in. Run until engine has warmed up then push choker all the way in, remembering to never use choker longer than necessary, as when not needed it has a tendency to foul up engine and ruin the lubricating oil in the crank case.

Next, set air screw for good idle by either turning to the right a little or backing out to the left as the needs of the engine require, remembering that first of all, the needle must be set as described. With the needle so set and the engine warmed up, the adjustment of the air screw for proper idling is easily accomplished by using a little care. If the air screw is turned in too tight, the motor will roll. If the air screw is not tight enough, the motor will hesitate and perhaps stop entirely. To make a nice clean adjustment for idle, first having set needle as described, turn air screw in quarter of a turn at a time until engine, does roll; then turn back to the left until engine hesitates, indicating that mixture has too much air and is too lean; next turn air screw in to the right three or four notches at a time until engine runs smoothly. This accomplished (and it is very easy to do by proceeding as directed above) the proper adjustment for the entire range of the engine will have been attained, thus insuring the best economy and power.

MODEL "S" MARVEL CARBURETER

STANDARD EQUIPMENT 1923–24 Series 691 Nash Sixes

If the engine idles too fast with throttle closed, the latter may be adjusted by means of the throttle lever adjusting screw.

#### RICH MIXTURE

An over-rich mixture will cause the engine speed to fluctuate through more or less regular periods from high to low speeds; the engine will seem to be mis-firing and there will be noticeable a strong odor, as well as, usually, a heavy black smoke from the exhaust.

#### LEAN MIXTURE

The best adjustment is obtained with the fuel and air valves set as described. It must be remembered that too lean a mixture as well as an over rich mixture causes over-heating and loss of power and is not as economical as an adjustment which provides just the proper proportion of gasoline and air.

CAUTION

It must be remembered that the low speed needle has been carefully calibrated to notch in disc handle and guide post above it, at the factory and that in making an adjustment that the needle must be so set and the rest of the adjusting done with the air screw as described, never varying from described needle setting unless in extreme cold weather, when a little more gas may be carried, or turning off a little when casing head gas is used in hot weather.

#### REPLACEMENT FOR PREVIOUS MODEL NASH SIXES

The Model "S" Marvel Carbureter is interchangeable with the Model "K" Marvel Carbureter, which was standard equipment on the 1922 and 1923 Nash Sixes of the early 691 series.

The previous series 681 Nash Sixes of 1921, 1920, and 1919, which were equipped with the Model "E" Marvel Carbureter as standard equipment, can be very greatly improved by the installation of the Model "S" carbureter, exhaust damper body assembly necessary for same, and the hot air stove assembly that goes with this installation.

Following is the complete Parts Price List of the Model "S" carbureter, damper body assembly and stove parts for same. Notice is called to the fact again that the damper body and stove parts are not needed on the early 691 series of 1922 and 1923.

1.F.
1.F.1. Project Gutenberg volunteers and employees expend considerable effort to identify, do copyright research on, transcribe and proofread works not protected by U.S. copyright law in creating the Project Gutenberg™ collection. Despite these efforts, Project Gutenberg™ electronic works, and the medium on which they may be stored, may contain “Defects,” such as, but not limited to, incomplete, inaccurate or corrupt data, transcription errors, a copyright or other intellectual property infringement, a defective or damaged disk or other medium, a computer virus, or computer codes that damage or cannot be read by your equipment.

LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the “Right of Replacement or Refund” described in paragraph 1.F.3, the Project Gutenberg Literary Archive Foundation, the owner of the Project Gutenberg™ trademark, and any other party distributing a Project Gutenberg™ electronic work under this agreement, disclaim all liability to you for damages, costs and expenses, including legal fees.

If any disclaimer or limitation set forth in this agreement violates the law of the state applicable to this agreement, the agreement shall be interpreted to make the maximum disclaimer or limitation permitted by the applicable state law. The invalidity or unenforceability of any provision of this agreement shall not void the remaining provisions.

Section 2. Information about the Mission of Project Gutenberg™
Project Gutenberg™ is synonymous with the free distribution of electronic works in formats readable by the widest variety of computers including obsolete, old, middle-aged and new computers. It exists because of the efforts of hundreds of volunteers and donations from people in all walks of life.
Volunteers and financial support to provide volunteers with the assistance they need are critical to reaching Project Gutenberg™’s goals and ensuring that the Project Gutenberg™ collection will remain freely available for generations to come. In 2001, the Project Gutenberg Literary Archive Foundation was created to provide a secure and permanent future for Project Gutenberg™ and future generations. To learn more about the Project Gutenberg Literary Archive Foundation and how your efforts and donations can help, see Sections 3 and 4 and the Foundation information page at www.gutenberg.org.

Section 4. Information about Donations to the Project Gutenberg Literary Archive Foundation
Project Gutenberg™ depends upon and cannot survive without widespread public support and donations to carry out its mission of increasing the number of public domain and licensed works that can be freely distributed in machine-readable form accessible by the widest array of equipment including outdated equipment. Many small donations ($1 to $5,000) are particularly important to maintaining tax exempt status with the IRS.
The Foundation is committed to complying with the laws regulating charities and charitable donations in all 50 states of the United States. Compliance requirements are not uniform and it takes a considerable effort, much paperwork and many fees to meet and keep up with these requirements. We do not solicit donations in locations where we have not received written confirmation of compliance. To SEND DONATIONS or determine the status of compliance for any particular state visit www.gutenberg.org/donate.
While we cannot and do not solicit contributions from states where we have not met the solicitation requirements, we know of no prohibition against accepting unsolicited donations from donors in such states who approach us with offers to donate.
International donations are gratefully accepted, but we cannot make any statements concerning tax treatment of donations received from outside the United States. U.S. laws alone swamp our small staff.
Please check the Project Gutenberg web pages for current donation methods and addresses. Donations are accepted in a number of other ways including checks, online payments and credit card donations. To donate, please visit: www.gutenberg.org/donate.
Section 5. General Information About Project Gutenberg™ electronic works
Professor Michael S. Hart was the originator of the Project Gutenberg™ concept of a library of electronic works that could be freely shared with anyone. For forty years, he produced and distributed Project Gutenberg™ eBooks with only a loose network of volunteer support.
Project Gutenberg™ eBooks are often created from several printed editions, all of which are confirmed as not protected by copyright in the U.S. unless a copyright notice is included. Thus, we do not necessarily keep eBooks in compliance with any particular paper edition.
Most people start at our website which has the main PG search facility: www.gutenberg.org.
This website includes information about Project Gutenberg™, including how to make donations to the Project Gutenberg Literary Archive Foundation, how to help produce our new eBooks, and how to subscribe to our email newsletter to hear about new eBooks.
