compensate for differences in fuel, temperature,
altitude and load. Refer to separate engine manual for
carburetor adjustment information.
NOTE:
A dirty air cleaner will cause an engine to run
rough. Be certain air cleaner is clean and attached to
the carburetor before adjusting carburetor.

Deck Leveling Adjustment

If an uneven cut is obtained, the deck may be leveled
by following instructions in Assembly section.
Deck Engagement Adjustment
The cutting deck engagement may be adjusted to make
certain deck is disengaged when lift lever is in the
BLADES STOP position. Correct adjustment as
follows.
With the engine off, place the lift lever in the highest
cutting position (first position). Remove the cotter pin
and flat washer which secure the disengagement rod to
the stabilizer shaft assembly. See Figure 13. Shorten
the rod by threading it in until the ferrule is against the
back of the slot in the lift shaft assembly, and the rod
lines up with the hole in the stabilizer shaft. For more
belt tension the disengagement rod must be
lengthened. To decrease belt tension the
disengagement rod must be shortened.
