Adjusting Engine Idle Speed

IMPORTANT!
A clean and unrestricted airflow is
essential to your blower's engine perfor-
mance and durability! Before attempting
any carburetor adjustments, inspect and
clean the engine air filter as described on
page 11 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!
1. Place the unit on the ground and start
the engine, then allow it to idle 2-3
minutes until warm.
2. If a tachometer is available, the engine idle
speed should be final adjusted to 2,200
( 200) rpm (min -1 ). See Figure 16.
