I was just able to spend a few minutes in the garage. I was able to snug the carbs tighter to the head do to the fact that my carb bracket was holding them away a 1/4 inch or so, there were telltale dust marks. It seems to be getting too much fuel. Backfires throughout throttle range , pretty randomly, and also when I let off but not immediately, takes a few seconds then backfires. does this mean I need to mess with the "d" screws underneath. At one point, prior to tonight, I twisted that knurled knob that bends up to the carbs but it didn't seem to make much difference. As far as the "t" shaped clip goes , I was looking at the wrong one. I didn't check it under load just on the stand (tomorrow hopefully). I did not change the pilot jets . The carbs don't seem to be cutting back and forth anymore since snugging them up. Again, I appreciate all the input , hope I'm being specific enough.
