12hp hunting

[nigel 150]

My engine governor seems to be cutting in all the time causing hunting, anyone know a fix ?

Have you tried adjusting high speed mixture   too lean can cause surging

 

Governor initial set and sensitivity

I saw the title and automatically went to "12 Ga. hunting"

Most common cause of rpm hunting would be carb/fuel related. If you can use the choke to even out the rpm and stop the hunting, it's fuel restriction from the carb. (The choke used would be matching air to fuel ratio)

Clean it thoroughly and it should solve the issue.

@nigel  have any fuel filters on that ? drop the fuel bowl , if its loaded with debris , its probably  fuel hose break down , also  fuel tank related , have a seperate gallon  jug  just for  running in any  carb issues , heavily treated with cleaners , easy to hook up to fuel pump , and run the engine in that separately , tune / adjust , with verified clean uuel , carb issues grow if not addressed , you are on track , pete
