2-14 FUEL SYSTEM
Read the WARNINGS in the Carburetor Removal.
The center lines of the carburetor bores must be parallel
both horizontally and vertically. If they are not, loosen
the mounting screws and align the carburetors on a flat
surface. Retighten the mounting screws.
After assembling the choke mechanism, check to see that
the choke plunger lever slides from side to side smoothly
without abnormal friction.
Fuel mixture trouble could result if the choke
plunger does not seat properly in its rest position
after the choke lever is returned.
Visually synchronize the throttle (butterfly) valves.
Check to see that the throttle valves open and close
smoothly without binding when turning the pulley.
Visually check the clearance [A] between the throttle
valve and the carburetor bore in each carburetor.
If there is a difference between the throttle valves, turn the
balance adjusting screw [B] to obtain the same clearance.
Clean the carburetors in a well-ventilated area, and
take care that there is no spark or flame anywhere
near the working area; this includes any appliance
with a pilot light. Because of the danger of highly
flammable liquids, do not use gasoline or low flash
-point solvents to clean the carburetors.
