8-6. Adjusting Engine Idle Speed

 

 

 

Y Stop engine and let cool.

 

 

 

Engine idle speed is factory set and

 

 

 

normally should not require adjust-

 

 

 

ment. After tuning engine, check

Engine Speed

 

 

engine speed with tachometer or

frequency meter. See table for

1850 rpm max

 

 

proper no load speed. If necessary,

 

 

adjust idle speed as follows:

(61.6 Hz)

 

 

Start engine and run until warm.

1250 rpm

 

 

 

 

On CC Models, place Stick/TIG
