Engine Swaps Help

Forums » Engine Swaps » Carb?


I can't get my engine to drop down to idle, anyone know what the problem is? Here's the scenario: 29 hp with good compression, had a minor air leak at front of crank so I replaced seal and engine seems to be pretty air tight now. Went through carb and installed new kit. Engine runs great but when I de-throttle the engine rpm does not drop down. If I leave the throttle on idle position the rpms will eventually slow down. It is not linkage it works fine. If I pull out the choke momentarily the rpms immediately drop down but then come back up again. Is the carb still feeding? anyone got any clues? Thanx
