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?

Re: Carb. Hesitation
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"?

Re: Carb. Hesitation
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

Re: Carb. Hesitation
Has anyone tried sanding down the metering rods? Making them skinnier.

Re: Carb. Hesitation
Easier to change jets or rods than sanding on them and probably a bit
more accurate. Work with your accel. pump by bending it so you have as much squirt left as possible when engine is stalled up on line.
