I will have to try your method of adjusting that accel pump arm.

I do have the hollow screw and run a pink cam. I always though the 42 seemed big... but it seemed to be what it wanted....

What else could be wrong that the large pump shot might be compensating for? I had the carb jetted on the dyno with wideband O2 sensors so I am pretty sure the jetting is right...

Any ideas?
