52Carl, Bartamos, Nah, I am not jumping on the veteran mechanics -they are buddies of mine. I am but a grasshopper next to them. But the fact remains that they were opening up and closing up the carb trying to figure out the cause of my symptoms and did not notice that one of the clamping bolts spins forever. It certainly was not stripped when I rebuilt the carb- that is something that even I would have known cannot be good. Now, is it the cause of my symptoms? I do not know. I will re-tap all four bolts out to 1/4" x 20 tpi from the current 7/32" x 28 tpi and see what results. There is no warpage between my air horn and float bowl. I checked that with a straight edge. No leaking, touch wood. I also found that the power piston had a larger check ball than specified by the manual. I changed that and I cleaned the entire carb again even though it was still squeaky clean from my rebuild. So we shall see...
