I have also adjusted the valves. Opened the carb again today. Didnt find anything obvious. Cleaned it and put it back together. No change at all. Tried to check for vacuum leak But Didnt find any of that either. Need some advise for further investigation. It idles very good, But when i try to rev it it pops and backfires and almost stalls. With 1/2 choke on, it revs perfect But idles alittlebit rougher.
