Adjusting Engine Idle Speed
IMPORTANT!
A clean and unrestricted airflow is essen-
tial to your blower's engine performance
and durability! Before attempting any
carburetor adjustments, inspect and clean
the engine air filter as described in the
maintenance section of this manual.
IMPORTANT!
Blower tubes and the air cleaner must
be in place while adjusting engine idle!
Engine idle speed will also be affected if
the blower tubes are blocked or incor-
rectly installed!
