...Went to 2 3/4 turns and only had a back fire twice on my test circuit. Balanced the carbs when I got back and they were out quite a bit. Haven't had a chance for another ride yet, but looking good. Need to go for just a ride, these 'test' rides are all well and good but I find myself trying to induce the backfiring, just need to forget that and see how it goes. Pretty happy so far though.



The correct balance should also help improve your situation. If necessary, the pilot screws can be run to 4 turns out with no worries. You have plenty of room to go.
