The D tool is on the way from Brent and I hope I get it by tomorrow. I will then see where the mixture (pilot) screws are from the factory and adjust them out to 3.5 turns or so a little at a time and see what happens. If it doesn't work, its on to the the jets. I kind of got into it with Bub's tech guy about fixing the popping. He did not want to give any guidance other than telling me to buy one of those aftermarket tuning kits. It kind of ticked me off. He had no advise on pilot screw adjustment or jetting and he said to call Dynajet!! A little trivia--My mixture screws do not have cover plates. I guess since I have the D screws. I will let everyone know if the adjustment works.
