This is for a friend of mine that is having some troubles if you guys have any ideas at all that would be great sorry for the length.

well i just bought a 750 dp quickfuel ss after numerous moving of vaccum lines and helicoiling two studs in the intake mani i got it on and running, car ran real good, then the fuel line started leaking, tried fixing it today and things got bad.

yesterday the car started right up and ran real good, today it seem to run really rough, seemed like a miss, while driviing i couldnt get the car over 3 grand and the whole time it sputtered and acted like it was trying to die jut around the block.

i dont hear it sucking air, and the idle doesnt hang so i dont thing its vaccum...

so my two thoughts are a fouled plug or the carb is loading up, niether of which i have dealt with so how can i spot them?

also i have a holley red electric pump and i had it pumping fuel for 10-15 seconds while i was checking for leaks, and i had started it after a hour or so sitting, it ran better but still real rough around 2500 rpms

and if anybody has any other possibibilties let me know.

 

idle hang is a caracteristic of a efi car not so much a carbed one....while it's running pull a wire one by one on cap and see which cylinder has no load change and that'll be the prob cylinder, from there check plug and wire

 

could it be that the choke is stuck open a bit? If so how do you check/fix it....its electric

 

the idle bump up feature could be causing the raised idle which is all part of the choke circuit, if the black cylinder like choke element is adjusted to tight it'll hold the choke on longer, all you should have to do is loosen the screws that hold it in place and rotate it so less tension is on it if that is the cause of his problem

 

This thing is constantly dripping fuel is it supposed to?

 

no it's not just adjust the float on the back bowl a little bit
