Choke Adjusting Screw Details

A Choke Adjusting Screw
NOTE: Choke is placed ON by moving throttle control
slightly past fast position. If throttle control does
not have a designated choke ON position, be
sure to leave suffi cient throttle control travel past
fast position. This will enable choke to be placed
ON.
1. Loosen control cable clamp.
2. Place throttle control lever of equipment into fast or
high speed position. Actuating tab of choke lever
should be just below end of choke adjusting screw.
3. Early Models: Early models use a single alignment
hole to set engine RPM. Align hole in throttle lever
with hole in speed control bracket by inserting a
pencil or 6.35 mm (1/4 in.) drill bit.
Later Models: Later models use a new control
assembly, identifi ed by two opposing alignment
holes (close to throttle lever pivot), instead of one.
Based upon intended high-speed (RPM) setting,
throttle cable adjustment must be made by matching
hole in control lever with correct alignment hole. Use
lower (left side) hole for high-speed settings above
3000 RPM. Use upper (right side) hole for high-
speed settings lower than 3000 RPM. Move throttle
lever to align hole in lever with correct hole in control
bracket. Insert a pencil or a 6.35 mm (1/4 in.) drill bit
to hold in position.
Current Models: Current models use a new control
assembly, identifi ed by three alignment holes (close
to throttle lever pivot). Based upon intended high-
speed (RPM) setting, throttle cable adjustment must
be made by matching hole in control lever with
correct alignment hole. Use appropriate hole for
corresponding high-speed settings. Move throttle
lever to align hole in lever with correct hole in control
bracket. Insert a pencil or a 6.35 mm (1/4 in.) drill bit
to hold in position.
4. Pull on outer shield of throttle control cable to
remove any slack. Tighten cable clamp securely.
