This one has me completely stumped - just bought another Scag Tiger Cub with the FH680V engine.
The engine hunts at idle and WOT - so far I have:
Changed spark plugs
Changed coils
Replaced fuel lines - filter and pump
Cleaned the carb and replaced gaskets
Set valve clearance
It will run stop hunting if I give it full choke but will run rough as it's over-fuelling.
I'm thinking it's a carb issue - but I have already given it a good clean.
Any suggestions on where I should look now ? Thanks.
