,series #fia ,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 gas4 ,the ,marvel ,model ,s ,carbureter is of the automatic air valve1 heat controlled type4 ,its outstanding advantages are3 #a4 ,simplicity of construction and operation4 #b4 ,quick starting in any weather4 #c4 ,automatically controlled heat application to ensure complete vaporization of fuels4 #d4 ,economy in fuel consumption4 #e4 ,ease of adjustment to meet varied driving and climatic conditions4 ,,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 bowl4 ,within the mixing chamber are two nozzles which proportion the amount of gasoline used in the mixture4 ,one of these nozzles1 called the low speed1 is regulated by the gasoline adjustment screw at bottom of carbureter and the other1 called the high speed1 is controlled by the automatic air valve4 ,an air screw is provided which regulates the pressure of the air valve spring enclosed therein4 ,within this screw is also enclosed a plunger connected by a link to the air valve4 ,the function of this plunger is to provide a resistance in addition to that of the air valve spring to assist in acceleration4 ,this arrangement of plunger and air valve screw is termed the dash pot4 ,a further control of the high speed jet is provided by the fuel metering valve operated by the carbureter throttle4 ,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 up4 ,during the ordinary driving ranges this valve controls the amount of fuel being used1 thus providing all the economy possible4 ,this valve is entirely automatic and requires no adjustment4 ,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 accelerator1 its position determining the amount of gas and air or mixture being fed the engine4 ,,starting ,a choke button is provided on the instrument board to assist in starting4 ,pulling out this button closes a butterfly choker valve 7see cut7 in the air intake passage of carbureter which restricts the air opening of the carbureter1 and consequently produces a richer mixture4 ,to start engine1 pull out choke button all the way4 ,advance spark lever about half way and throttle lever about one-quarter way and depress starter pedal4 ,as soon as motor fires when starting1 this control should be released part way1 otherwise too much fuel will be drawn from carbureter1 causing flooding of the motor and failure of the latter to continue to promptly fire4 ,after starting1 motor should be allowed to run part choke as stated for a few minutes while warming up1 then the choker control should be fully released1 or pushed in completely on the instrument board1 and engine allowed to run normally for sometime until water in cylinder jackets is thoroughly warmed up before starting to make final carbureter adjustments4 ,,heat ,,control--,,stove ,in the colder seasons warm air is fed to air intake of carbureter through the warm air elbow ,f 7see cut74 ,this elbow connects the carbureter with the warm air stove1 which is a casting surrounding the two exhaust heat tubes which supply exhaust heat to the carbureter jackets as described below4 ,the amount of heat required for proper carburation depends on the temperature of the outside air4 ,the first means of control is in the warm air stove just described1 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 #ej deg4 ,f41 whenever the outside air temperature runs above this point cold air should be furnished to carbureter air intake4 ,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 carbureter1 after which slide elbow out of air intake and revolve it--#ahj degrees about an horizontal axis and re-insert in carbureter air intake and lock in place with set screw4 ,the opening in the elbow now is turned down away from the stove and draws in only cold air4 ,the above procedure1 it must be understood1 will vary somewhat due to differences in locality1 altitude and fuels used1 but it should be borne in mind that the best economy can be had with cold air passing to the carbureter1 and the stove should not be connected until the acceleration and performance of the job requires the use of warm air for the best results4 ,the adjustment of the carbureter should be made per the above description of the stove1 as the latter is used for meeting weather conditions and should be set as described4 ,,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 fuel4 ,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 engine2 this valve body1 housing a large valve called the main-exhaust-heat-valve 7,c in cut7 within the body itself1 the return or outlet tube from the carbureter heat jacket entering the valve-body in the lower portion below the main-exhaust-heat-valve4 ,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 it4 ,the purpose of the carbureter heat jacket and valve in exhaust line with connections described1 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 automatically4 ,the automatic feature of same is accomplished by setting the ,main-,exhaust-,heat-,valve ,c by means of the long connecting rod1 in closed position with the closed or idling position of the throttle valve1 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-,valve1 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 increases4 ,illustration3 ,,heat ,,setting ,no4 #a ,by referring to the cut shown 7,see ,page #e7 and noting ,heat ,setting ,no4 #a1 it will be noted that valve ,c in main exhaust line is fully closed with the closed or idling position of the throttle valve4 ,this adjustment is accomplished by having long connecting rod ,r from valve ,c ,lever set in ,hole ,no4 #a1 in ,throttle ,lever ,l1 being sure that when throttle valve is standing in fully closed or idling position that valve ,c is also in closed position1 proving out the latter feature by loosening connection of valve ,c lever holding long connecting rod2 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 position4 ,after having made the adjustment as just described1 it is assured that ,heat ,setting ,no4 #a has been properly made and that all of the heat possible from the exhaust has been secured4 ,this ,heat ,setting ,no4 #a1 provides as stated1 for the most exhaust heat obtainable and should be used during the entire year1 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 heat4 ,if loss of power or mileage due to too much heat is experienced1 first be sure that it is not due to driving on hot-air instead of cold-air4 ,after making this observation1 if there is still too much heat1 refer to cut 7,see ,page #g7 describing ,heat ,setting ,no4 #b4 ,it will be noted that connecting rod ,r from valve ,c is removed from ,hole ,no4 #a1 in ,throttle ,lever ,l and placed in ,hole ,no4 #b1 in ,throttle ,lever4 ,this change is all that is necessary in order to reduce the amount of heat applied to carbureter4 ,in ,heat ,setting ,no4 #b1 when the throttle is in closed or idling position1 valve ,c is quite aways off its seat4 ,this adjustment provides for a great deal less heat than is provided by ,heat ,setting ,no4 #a and is all that is required in the reduction of the volume of heat together with driving on ,cold air for the main-air-supply1 in the warmest weather or hottest climates4 ,illustration3 ,,heat ,,setting ,no4 #b ,,note--,after original position of valve ,c is made as described in ,heat ,setting ,no4 #a do not again readjust valve ,c on connecting rod but when changing from ,heat ,setting ,no4 #a to ,heat ,setting ,no4 #b1 merely change position of long connecting rod from ,hole ,no4 #a to ,hole ,no4 #b in throttle lever4 ,,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 unit4 ,it should be noted that the gasoline lines are clear1 that there is gasoline in the vacuum tank1 that there are no leaks at connections between carbureter and engine1 that the ignition system is in proper condition1 and that there is even compression in all cylinders4 ,if it is necessary to test adjustment or to make a readjustment proceed as follows3 ,set air screw so that the end is flush with the end of ratchet set spring4 ,loosen packing nut on needle adjustment4 ,turn gasoline adjustment to the right very carefully so as not to injure the needle point1 until the valve is closed gently against its seat4 ,then turn to left approximately one complete turn which will bring notch in the disc handle directly below the guide post above it4 ,tighten packing nut to hold needle firmly as set4 ,the notch in disc handle of needle is put in handle after the needle has been carefully calibrated by a flow-meter at the factory1 therefore the notch in handle should register with guide post above it4 ,this setting of needle valve is absolutely essential to get the best results4 ,the object in directing that needle be first turned to the right until closed is to insure against two or more turns open1 as from closed position to notch 7usually about one turn7 is the normal setting4 ,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 left1 to the notch registering with guide post1 that the needle is not more than once around or one turn from its seat4 ,set stove heat and damper heat as previously instructed above4 ,pull out choker to closed position and start engine in usual manner4 ,as soon as engine has fired release choker three-fourths of way in4 ,run until engine has warmed up then push choker all the way in1 remembering to never use choker longer than necessary1 as when not needed it has a tendency to foul up engine and ruin the lubricating oil in the crank case4 ,next1 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 require1 remembering that first of all1 the needle must be set as described4 ,with the needle so set and the engine warmed up1 the adjustment of the air screw for proper idling is easily accomplished by using a little care4 ,if the air screw is turned in too tight1 the motor will roll4 ,if the air screw is not tight enough1 the motor will hesitate and perhaps stop entirely4 ,to make a nice clean adjustment for idle1 first having set needle as described1 turn air screw in quarter of a turn at a time until engine1 does roll2 then turn back to the left until engine hesitates1 indicating that mixture has too much air and is too lean2 next turn air screw in to the right three or four notches at a time until engine runs smoothly4 ,this accomplished 7and it is very easy to do by proceeding as directed above7 the proper adjustment for the entire range of the engine will have been attained1 thus insuring the best economy and power4 ,,model ,s ,,marvel ,,carbureter ,illustration3 ,,standard ,,equipment #aibc-bd ,series #fia ,nash ,sixes ,if the engine idles too fast with throttle closed1 the latter may be adjusted by means of the throttle lever adjusting screw4 ,,rich ,,mixture ,an over-rich mixture will cause the engine speed to fluctuate through more or less regular periods from high to low speeds2 the engine will seem to be mis-firing and there will be noticeable a strong odor1 as well as1 usually1 a heavy black smoke from the exhaust4 ,,lean ,,mixture ,the best adjustment is obtained with the fuel and air valves set as described4 ,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 air4 ,,caution ,it must be remembered that the low speed needle has been carefully calibrated to notch in disc handle and guide post above it1 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 described1 never varying from described needle setting unless in extreme cold weather1 when a little more gas may be carried1 or turning off a little when casing head gas is used in hot weather4 ,,marvel ,,carbureter ,,model ,s ,illustration3 ,nash ,series #fia ,sixes ,parts ,price ,list ,part ,no4 ,name ,price #aj-hj ,carbureter ,body
