.having car trouble...been messing with the damn carb for the last couple days because the car was running like absolute crap....i tore the carb down, clean it and blew it out and reassembled it back to what the holley book says



the carb is a 4160 600cfm vs

the car turns over and is getting fuel...i would get it to idle but would idle like complete crap....i would give a little gas and it would backfire really bad and stumble.....distributer problem??

when i reset the carb the fuel mixture needles were set to 1 1/2 turns out on both sides...the accelerator pump was shimmed @.019 @ WOT like the book says..


distributer problem??...its a mallory unilite ..nothing was ever touched for ignition prior of this to my knowlege...what could go wrong with this?...

 

This might sound simple. but check to make sure the plug wires are on the distributor in the right order. 1-8-4-3-6-5-7-2. If a couple were swithed it would run like dookey.

The number one post on the distributor is the one on the front, drivers side when looking at it from the top.. The rotor rotates clockwise so the plug wires should follow the firing order from there.

Also, check the timing.

If you have a MSD box, do the testing with the box disconnected.

 

i figured it out....bad control mudule...i am replacing the distributer with a gm hei/digital 6

 

had that happen on a buddies race car, 10 second 70 camaro

 

yea...it was a damn pain...giving me the signs of a blown power valve...
