Carb. Hesitation
I'm running a 340 with a carter AVS. I was wondering if anyone has ever had trouble with a hesitation on the starting line during acceleration?

Check accelerator pump and jetting.

Re: Carb. Hesitation
I changed the accelerator pump and it helped it. But it still has a slight hesitation?

Re: Carb. Hesitation
Have you tried drilling the squirter holes to something like .035"?

Look at the air door tension.

Re: Carb. Hesitation
Tighten the air valve spring, it needs to be pretty tight on them. Put the accelerator pump rod in the hole that gives the most travel of the pump, I think it's the outer hole.

Re: Carb. Hesitation
I have the air valve a little loose now. I will give it some more tension. I've got the pump rod in the outer hole it seems to work the best there
