If you look close at that pic you can see a crescent on the edge where it was tightened down originally, I just set it there to see how it went. When i started it, it sounded different...Just went for a nice long ride and it's running great! Pulls smooth in all gears and there's power anytime I give it throttle, no hesitation or stumble, no pops or backfires. Unbelievable oversight that gave me so much grief! Thanks for all your help guys, seriously grateful I suppose I should verify the timing, make sure the valves are adjusted and resync the carbs
