Few carb issues
I just installed my eledbrock performer intake mani and holley carb on my 84 F250. Overall, I am more than pleased with the setup, but theres a few issues I want to iron out.
First, at idle, if you punch the throttle hard, it stumbles a bit like its getting too much fuel. If you dont stomp on it, it revs fine.
Also, when you rev up to higher RPMs, it will pop through the carb. it never does this at lower rpms or if you are maintaning one RPM speed.
Finally, I dont know how to hook up the wire for the electric choke. the blac wire is grounded, but the white wire goes nowhere. Where should I wire it in to?
Keep in mind the accelerator pumps seem to be working fine, and it holds steady 20" vac at idle. Thanks

I had this problem on the holley 650DP on my 67 stang. I think I have the problem figured out but have been unable to test it since I pulled the tranny and 3rd member out. Having the wrong power valve can cause that problem. I was directed to holley's website where I read that you want a power valve that is half of your vacumn reading at idle. My mustang had 9" of vacumn at idle so I got a 4.5 power valve. The standard holley kit comes with a 6.5 power valve. Since you get 20" of vac. at idle you might try and get a 10 power valve.

Have you tried revving it while holding the timing light on the marks? Do you have a way to apply vacuum to the cannister w/ the line disconnected and plugged?
As for your choke it should connect to a wire that gets power in start and run. On my 460 this comes out of the harness by the alternator plug.
Hope this helps...
