CARBURETORADJUSTMENT
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 all moving parts.
Be 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
