For a pressure washer, generator, lawn mower, etc this is of course standard... for anything else with an engine requiring throttle control this is backwards and completely wrong.
Fixed speed engines and those that have throttle control operate the same way and use the same components.
Fixed speed the governer spring is hooked to a fixed point to set a constant RPM. Bending this tab adjusts the set speed.
On a small engine with throttle control, instead of the spring going to a fixed point, it is hooked to a
throttle control lever that can adjust the tension on said spring to regulate the speed of the engine.
Ive had no cam issues running the GC160/190's ungoverned, the timing belt driven OHC's
dont seem to care. The governer gear is driven off the crankshaft on these engines.
But still the GX is superior.
