Hercules — To Adjust the Governor
Adjustments
From a Hercules owner's manual — check it applies to your exact model before use.
Before you start
- Never attempt to make governor, carburetor or ignition adjustments unless the engine is at operating temperature.
Procedure
- Start the engine and warm up to operating temperature.
- Stop the engine.
- Adjust the length of the rod between the governor and the carburetor so that with the governor lever in full load position the carburetor throttle lever is just off the full speed stop.
- Move the governor lever to no load position; the carburetor lever should now be at the idle position, secure the rod.
- Start the engine and check the engine speeds; adjust the throttle linkage (not the governor rod) if necessary.
