CARBURETOR ADJUSTMENT
Throttle Valve Synchronization
All throttle valve synchronization adjustments are made to the
MAG throttle valve. The PTO throttle valve is non-adjustable
and considered the base throttle valve.
Throttle valve synchronization can be performed with the
carburetor rack installed or removed from the engine.

If running, turn off engine. Remove the air box.
2.
Remove the carburetor covers.

The bottoms of each throttle valve should be flush with the
top of the intake bores.
5.
If adjustment is required, hold the PTO carburetor flush
with the top of intake bore. Turn the throttle stop screw in
or out to set the PTO throttle slide flush with the intake
bore.
