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!
