Spud Miller's Cave / Re: injected sbc hard to start

Bruce good to see you here!!!  It's not like that.  If i prime it any at all, it just blows white smoke out collector's till it finally fires up like I said above, rev up real high, then drops way low, you think that its gonna shut off, but, then it comes up on the pump. You ought to see the expressions of the people in the staging lanes when it cranks up!!  I wonder if I shim the idle check valve to say 4 psi.  Would that cause any other problems?  It's a Bird on a Edelbrock tunnel ram, with a Enderle cube, #30 flowed nozzles, a 1/2 DSR belt driven pump.

Spud Miller's Cave / injected sbc hard to start

I'm a newbie to this site, but, I have checked all posts and can't find anyone having the problem I'm having.  Here it is, I've got a 421 sbc injected alky altered.  After I shut it down in the staging lanes, then when restarting, it revs up to maybe 3000 rpm, then immediately slows down to about 3-400 rpm,  it just barely runs, then, it will come up on the pump and run fine.  I think that my idle check valve which is set to 2psi is maybe leaking fuel past it because it's at the very bottom of my tank which is at the bottom of my chassis.  Can anyone help me with this?
