I am having a issue with my port engine on my speedster. It chokes up on transition from low to full throttle. I pulled the choke to check for lean condition but made it worse. If I back off it continues choking for a few. If I just throw the throttle from low to full it gets past the choking and runs great reaching full rpm. When I back down from full it runs normal and can be accelerated/decelerated without issue until I go back down to low throttle. Then it begins the choking again. I thought it might be just loading up, but after a long run at near full speed it immediately started choking again when going from low throttle. This first appeared at the end of the day 2 outings ago when we went to go load it on the trailer. I thought maybe it had loaded up from the idling. It had run strong all day pulling tubers and doing full speed runs. I had also changed the plugs that outing and yes I did properly gap them first and used dielectric grease. Just on a hunch I tried changing to the old plugs in case one of the new ones was fouled, no change. Also the new plugs looked perfect. A little background info: I only run 100% fuel; always stored with a full tank and stabilizer; winterize it myself each year; compression in both cylinders was 150psi wot at winterization; no grey lines; I always run the blower for 3-5min prior to starting; the starboard engine runs great. I have not cleaned the carbs nor raves yet and suspect one or the other is causing this. What do ya’ll think? Any help is much appreciated.
