CONTROL PLATE (THROTTLE AND CHOKE)
This section covers the description, location, and operation of the engine controls including throttle and choke
cable mounting, governor troubleshooting, “zero” adjustment and top no-load RPM adjustment.
WARNING: Unauthorized adjustment to the carburetor or fuel system may make the machine non-
compliant to EPA standards. Make sure components are set to factory standards.
WARNING
Explosive fuel can cause res and severe burns.
Do not ll fuel tank while engine is hot or running.
Gasoline is extremely ammable and its vapors can
explode if ignited. Store gasoline only in approved
containers, in well ventilated, occupied buildings, away
from sparks or ames. Spilled fuel could ignite if it
comes in contact with hot parts or sparks from ignition.
Never use gasoline as a cleaning agent.
