SHIFT ROD ADJUSTMENT
CARBURETOR ADJUSTMENT
To adjust the shift rod, remove the cotter pin which
secures the shift rod to the shift lever. For proper
adjustment, refer to FINAL ADJUSTMENTS on page
6.
WARNING: If any adjustments are
made to the engine while the engine is
running (e.g. carburetor), keep clear of
all moving parts. Be careful of heated
surfaces and mufflers.
SKID SHOE ADJUSTMENT
Minor carburetor adjustment may be required to
compensate for differences in fuel, temperature,
altitude and load.
The space between the shave plate and the ground
can be adjusted. Refer to Skid Shoe Adjustment
(See Figure 8) on page 6.
Refer to the separate engine manual packed with
your unit for carburetor adjustment information.

to
comply
with
suggested
maintenance and lubrication specifications on pages
10 and 11 will void warranty.
