If the engine is adjusted for operation above 335 m (1,100 ft.) ASL, 
the carburetor must be re-adjusted when operating the engine below 

335 m (1,100 ft.)  

ASL, otherwise severe engine damage may result.

Level 2.

Note:  Every unit is run at the factory and the carburetor is set in 

compliance with emission regulations. Carburetor 

adjustments, other than idle speed, must be performed by an 

authorized Shindaiwa dealer.

Before adjustment make sure that:
• Air filter is clean and properly installed.
• Spark arrester 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

“Specifications” page of this

manual. Turn idle screw (A)

clockwise to increase idle

speed; counter clockwise to

decrease idle speed.
