I agree 351, spraying carb cleaner around the seals on carb, manifold, intake didn't seem to change anything but I'll try to re-seat and tighten down again and see if that helps. I was assuming the initial bogging was the pumper dumping fuel the motor couldn't handle standing still to WOT. I realize the 30mm pumper is probably too much carb right now, but if I go light till it just starts rolling THEN nail it, it SPINS the rears and takes off like a mad man. On a fairly straight stretch where I'd get to about 28-30MPH, she was at 35 and still pulling.. FYI 35 pilot 135 main @ sea level with 110 Octane leaded racing fuel.
