Does any one sell a longer full fuel screw? When i was turning mine in it came to a stop. Now that I have pump off I can see that the screw bottomed out.

do the I/C pumps have longer screws than the non i/c pumps? When i had my pump top off a few weeks go, my fuel screw was longer than one on a non i/c pump I have torn apart.

I welded mine & I still cant find runaway whats up with that but it runs good

Ha ha do you really want to? I've gone about as far as I've dared with mine, I think its pretty close though, and it runs good so I'm gonna leave it.

yes I would like to find it may be in the high 12s if i do

The screw in my buddies 93 is the same length as my 90


I bought a screw from the local pump shop - it was 1/4"? longer then my stocker. - Was like $6

How do you know when you are close to runaway? And how do I tune my pump to get the most power out of it and not have it runaway?

Same here, I have a non I/C pump I picked up as a spare and to tinker with. Both screws are identical length.

Does it have a collar tack-welded at the end?

I picked up my fuel screw friday. It is the same size as my old one. Does any one have an overall length for the screw. If I already have the longer screw why can't I get to a run away condition.

What is the length of the two available fuel screws?

Same here, my pumps bottomed. Are the screws the same price art every store or do they fluctuate.
