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.

Place the unit on the ground and start 

1. 

the engine, then allow it to idle 2-3 min-

utes until warm.
If a tachometer is available, the engine 

2. 

idle speed should be final adjusted to 

2,000 (±200) min

-1

. See Figure 16.

NOTE:

Carburetor fuel mixture adjustments are 
preset at factory on units with emission 
control systems and cannot be serviced 

in the field.

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!

for warm or cold engine. If the engine 

still will not start, follow the “Starting a 

Flooded Engine” procedure.
