Hello. I bought a Methanol carb from a speedway guy. Turns out it's a home converted 850 annular discharge DP. It has 50cc pumps front and rear. I want to run it on my very light race only car. It has a horrendously heavy pull on the accelerator cable on the secondaries. Looking for why I removed the brown pump cam from the secondaries and it is way different. This cam is the most aggressive Holley list. I figure a dirt track car is on and off the throttle so needs the pump shot where my drag car doesn't and would benefit with a longer slower delivery. Anyone agree or disagree. What secondary pump cam have you used on a drag only car. It's a foot brake car leaving at about 3000 rpm by the way.
Cheers
