can you see fuel shoot out of the fron and back when you look down the carb and move the throttle(engine off of course).

Do you have a lot of play between the linkage arm to the pump arm?? I think holley says to leave a little clearance but i think it is best to just take up any clearance and stop so they are just touching. that way there is no delay in pump action.

have you checked that little umbrella valve in the pump?? If it doesn't seal the pump will try to force fuel back into the bowl not into the carb.

Also is you pump cam on the throttle shaft OK or is it wearing away?? if it wears away then your pump shot decreases and get increasingly worse.

Just some things to check. Let us know if you find the problem.

dirtracer, maybe help maybenot,first of all, a quick reveiw. check timing , pull plugs see how they are burning,another is what is your idle out on the track ,under yellow or at restart?we found that 1200 -1500 rpms are great ,much better throtle response, on take offs. hope this helps.
