Maintenance and care

Carburettor adjustment

Engine Break-In

New engines must be operated a minimum duration of two tanks
of fuel break-in before carburettor adjustments can be made.
During the break-in period your engine performance will increase
and exhaust emissions will stabilize. Idle speed can be adjusted
as required.

High Altitude Adjustment

High altitude adjustment is not required for proper operation of
this engine.

Tools required: Screwdriver, tachometer
Parts required: None

Before Adjustment

Check that:

Air filter is clean and properly installed.
Spark arrestor screen is free of carbon.
Blower pipes are installed.

1.  Start engine, run at idle for one minute.
2.  Complete warm up by running at full throttle for 5 minutes, 

operating choke twice to clear air from carburettor cham-
bers.

3.  Check idle speed and reset if necessary. If a tachometer is 

available, idle speed screw should be set to the specifica-
tions found on Page 29"Specifications" of this manual. Turn 
idle screw clockwise to increase idle speed; counter clock-
wise to decrease idle speed.

1. Screw

NOTE

Every unit is run at the factory and the carburettor is set in com-
pliance with Emission Regulations. This carburettor does not 
have acceleration and high speed adjustment needles.
