CARBURETOR
• The function of the carburetor is to mix fuel with air.
Adjustments other than Idle speed should be made by
a servicing dealer.
• Before adjusting the engine idle speed, make sure the air
filter is clean and the engine is warmed up.
T – Idle Screw is adjusted so that the engine idles smoothly
but the clutch does not engage.
• If cut-off saw has been running satisfactorily and there is a gradual decrease in power
and drop in RPM at full throttle, the filter may have become dirty or saturated with
water. .
