Needle and seat size? - 08/30/12 02:09 PM
My needle and seat failed last Saturday's race in the semi's (Grrrrrrrrrrr) so I need to replace them. I can't remember, do I want 0.110", 0.120", or 0.130"? Cab Burge had a post on this a while back, but I can't find it.
This is going in my Proform 750dp on my small block stroker.

.110 is stock... on all the carbs less than 1050 I
put in a .120(1050 comes with .120)

Like most women, carbs seem to like bigger than smaller
I would put in .120

Just put the stock one in. I have some monster, like a .150, when you turn the fuel pump on (everybody drag racing today has too big a fuel pump) it shoots fuel in so fast that it blasts the float to the bottom of the bowl and won't let it come up to stop the fuel coming in. Then it starts coming out the vent.
