Carburetor Adjustment

It is generally not necessary
to adjust the mixture screw
on the side of the
carburetor. This screw is
preset at the factory and
will have little effect on the
performance of the
carburetor.
1. If this screw has been removed
for cleaning of the carburetor, it
should be reset carefully. The
standard setting is two turns out,
plus or minus1/4 turn.
2. To set this position, run the
engine until warm and allow it to
idle. Turn the screw in or out a little
at a time and measure the idle
RPM. The correct setting is
achieved when the idle speed is
maximized.
3. Adjust the idle speed of the
engine once the engine has been
warmed up.
4. Set the warm idle speed to
1900RPM, plus or minus 100RPM.
5. Check for engine return to idle
speed after running at part throttle.
6. Make sure that the throttle
cable allows the throttle control
plate to return to the stop screw.
7. If needed, readjust the mixture
screw to help stabilize idle
performance.
