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 on page
10 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 incorrectly
installed!
1. Place the unit on the ground and start
the engine, then allow it to idle 2-3 min-
utes until warm.
2. If a tachometer is available, the engine idle
speed should be final adjusted to
2,200 (min ).
