what is your jetting and elevation????? What are your mods??????? are you trying to go from idle to WOT????? if you are then none of the above matter because you cant go from idle to WOT using a pumper carb.
thanks edger thats what i was checking, it did it stock, figured it was the pumper causing the problem. I am running 45 pilot, gytr needle in 4th position, and a 175 main. with a sparks pipe and lid off.
