1985 br. Freshly rebuilt top end. kitted the carb because it was leaking out of the overflow and1 br fire is enough. Cannot get rid of off idle stumble. Set needle clip in middle position. It was in next to bottom. It idles perfectly. Choke seems to be working fine. moved needle clip down one. I have had the air screw from1/4 turn out to 4 & 1/2 turns. If you pin throttle and hold it off idle it will actually die. Cranks right back up. if you gradually accelerate, it will go wide open. once rpms are up, it will continue to respond fine. when you stop and come back to idle, same story. Where do I go from here?
