got a RN superjet with a stock 760 with 38mm carbs and a b-pipe. I have 135 high jets, 70 lows, 2.0 needle, and i believe 95g springs. I had 140 jets and it seemed to run rich then I put the 135's in and turned the high speed screws in all the way and it still bogs over 1/4 throttle. It idles fine and goes to 1/4 throttle fine but then bogs after that. I checked the spark and it was a cloudy day and I could just barely see the spark. Is that normal, would a weak spark cause it to run like that?
Super Jet Cannot figure out bogging issue
