the tie rod end from the wheel bracket. See figure

WARNING ^
If any adjustments are made to the
engine while the engine is running
(e.g.
carburetor),
disengage
all
clutches and blades. Keep clear of

careful
of
heated surfaces and muffler.
Minor carburetor adjustment may be required to
compensate for differences in fuel, temperature,
altitude and load. To adjust the carburetor, refer to the
separate engine manual packed with your unit.
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.
Refer to the separate engine manual.
