I recently dusted off my old girl and did an complete maintenance on her seeing how she sat for a year. It fires right up second kick but I have to find a sweet spot on the choke to keep it at choke idle. After warming up is where my issue comes in. As long as I have the throttle open just a hair it will stay running. It won't stay at idle and backfires horrible. Bogs like a dog at wot in 5th. Any ideas guys?
