Friend dropped off this mini bike, "cant get it to run right". 5hp Chinese Honda-ish clone. Lots of problems at first look. Throttle return spring and governor spring missing and of course the governor shaft was loose as he had removed the bolt that secures it to the shaft.
So I cleaned the carb, cleaned the fuel tank, new fuel line, new spark plug gapped correctly, new springs attached correctly based on distributor tech services. Starts up and keeps running. Problem is it does not slow down to "idle", clutch is still engaged at no throttle and when turning the handle bar throttle to full no change(engine does not rev up). If I move the throttle on the carb the governor "engages" and it speeds up like I assumed it should.
My thought here is that the governor is not operating correctly due to the owner removing the bolt that holds the governor arm to the shaft. Not sure how to "adjust"/ "set" the governor correctly? Should it be done with all springs connected or should they be disconnected? I have seen some threads along time ago here on proper governor settings for lawn mowers with Briggs or Tech engines. Don't know if that would be general for this or not? Will have to look for that thread.
Am I thinking correctly? Any tips on setting governor?
Thanks.
