Choke and Air Intake System
S10 FE350 FUEL SYSTEM
7.
To reduce RPM, loosen the accelerator cable retaining nut on the outside of the electrical box wall and tighten
the retaining nut on the inside of the wall until the specified RPM is reached
. To
increase RPM, loosen the cable retaining nut inside the electrical box and tighten the nut outside the box until
the specified RPM is reached.
8.
Be sure both retaining nuts are locked against the electrical box and then check the RPM again. If the RPM
needs to be adjusted, repeat step 7.
9.
If more adjustment is required than the cable housing will allow, make sure the spring on the other end of the
accelerator cable is properly positioned. Excessive belt and torque converter wear can also prevent proper RPM
adjustment. Check them for excessive wear.
See Section 19 — Torque Converter .
CHOKE AND AIR INTAKE SYSTEM
See General Warning on page 10-1.
GENERAL INFORMATION
The choke system is a simple mechanism requiring very little or no maintenance. The system consists of a choke
assembly that is attached to the driver side of the front body, an air filter housing with a hose that is attached to the
carburetor, and an air duct that provides the engine with air from outside the engine compartment. Clean, cool air
is drawn through the choke assembly and into the air cleaner intake. This feature increases engine horsepower
and extends air filter life.
The choke system aids in starting the engine in cold weather. When starting a cold engine, the choke cable handle is
pulled. This restricts the air flow, creating a “fuel rich” mixture in the carburetor. The choke cable handle is pulled
until the engine starts, and then is released. The air flow to the engine is no longer restricted, and the engine
operates normally.
The choke assembly is adjusted at the factory and does not require field adjustment; however, if the choke assembly is
subjected to abuse or damaged, it may become necessary to replace the assembly.
