If any adjustments are made to the
engine while the engine is running
(e.g. carburetor), disengage ail
clutches and blades. Keep clear of
all moving parts. Be careful of
heated surfaces and muffler.
Minor carburetor adjustment may be reqLired to
compensate for differences in fuel, tempfirature,
altitude and load. Refer to the separate engine
manual packed with your mower.

when attempting to engage the
blade, the carburetor mixture should,
be adjusted 1/8 turn richer (counter­
