Started my car tonight and it wouldn't idle. Then when I shut it off and tried restarting it would crank then stop think it is dumping alot of fuel. Just rebuilt would it be the needle and seat? Float level it right at the bottom of the hole. Thanks

I put another new power valve in it Tonight along with float Needle and seat. It just keeps dripping gas all the time I can open the butter flies and see it puddling up in the intake.

Float to high, pressure to high, throttle blades open to far and exposing to much transfer slot, Idle to high. If it's a four holer, try opening the secondary's so about .020 is seen at the transfer slot. Then close the primary's till you regian control of idle circiuts.

Does it have an HP style metering block? If so, there is a hole in the main body (the timed spark vacuum port hole) that needs to be plugged otherwise fuel will pass from the idle well in the metering block right thru that hole in the main body and down directly into the intake.
If you're looking at the metering block surface on the main body with the block removed, it's the hole in the lower left side just to the right of the bowl skrew hole.....

how fast can you get it to me? I'd do my best not to cause you to miss a race, but you'd have to pay priority shipping fees.
If I just put ya at the end of the line behind everyone else's jobs we have right now, you're looking at somewhere in mid-June, but we juggle so many priority jobs at once, it's hard to give a solid estimate of what our turnaround time is because it changes daily.
Once we start a 2bbl job, it's done in 1 day no matter HOW complex it is.
