Idle Adjustment
Before adjustment make sure that:
• Air filter is clean and properly installed.
• Spark arrestor screen and muffler are 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 carburetor chambers.
3. Check idle speed and reset if necessary. If a tachometer is
available, idle speed screw (A) should be set to the specifications
found on Page 29 "Specifications" of this manual. Turn idle screw
(A) clockwise to increase idle speed; counter clockwise to
decrease idle speed.
