Aye up guys, looking for advice on my latest project, engine rebuilt, new rings hone etc, started first time after rebuild. However, revs hang, won't idle at 1000 to 1200 rpm, left carb shows higher pull than right carb, twice as much, checked for air leaks, all seem good, had carbs off and checked, good blue flame on the gunsun , starts ok. When hot, but the starts to climb the revs up to 2300 rpm And hangs, if I hold the throttle tight down it does drop revs but then climbs back. I'm baffled of Bolton. Cables set as per spec. Any thoughts.
