OK, I haven't been on for awhile. Work, church and the shop keeping me real busy. I finally got back to my 73 SE. It has an Edlebrock Torker and Holley Carb. I have replaced the plugs, wires, dist. cap and coil. Not the rotor yet. It runs like a brand new car until it warms up. Then it will not idle. It's like it runs out of gas. It starts right back up and will run as long as I keep accelerating, but will not idle. Let it cool back down and it idles just fine. I'm hoping someone else has had this problem and it's something I'm overlooking. Please help.

Update: Installed new rotor during lunch...same results. After a little thought, I beleive the car had this problem from day one. I thought it was just in need of a major tune up and old gas. These have been fixed. It came with a Carter T-Quad that looks as if it has been purchased from a parts store and never installed. Thoughts anyone?

Sounds like the idle adjustment screw needs to be played with since it does start and run when cold. Don't have a Holley, but the red tipped screw on my TQ. Have a friend keep engine running after warm up and adjust screw in until it will keep running on it's own. Have you messed with the air/fuel screws on the front base of carb? If so, screw both all of the way in and then back out 1 1/2 turns on both. Kinda hard making determination of problem without hands on.  |

Has it ever idled correctly? I don't know much about Holley but have you tried turning the idle screw in a bit to raise the idle?

It's idled up more than normal. No it has never idled once warmed up. But like I said, I knew it needed freshened up gas and the complete tune up, which is now done. I've never been much on the aftermarket route, but I have seen lots of people have good results. It just seems to run out of gas once warmed up at idle. The Holley has an air adjust on the drivers side with only app. 2 turns to it and a lean adjust on the pass. side the same way. There is no difference in the running adjusted all the in or out on both of them. They are both plastic headed.

Vacuum leak? If you believe it's too lean, and the mixture screws (mentioned above) are ineffective, you may have a vacuum leak. This would go along with your comment that it "idled up more than normal", if by that you are referring to idle rpm.

I have the idle adj. screw in more than normal to try and keep it running when warmed up. I have looked high and low for a vacuum leak, but I could be overlooking it. Like I say, this car has more power and runs better than I can imagine, except at warm idle. At cold idle the choke stays almost closed. (Electric, disconnected) As it warmed up, i tried to open it manually and if I open it any at all, just even a fraction, the engine dies.

It sure seems to have symptoms that point to a vacuume leak.

I think I'll have to agree with Cooter on dodgecharger.com. He thinks my carb's got junk in it and is need of a rebuild. I have tried everything. Once I get the time to tear it apart, I'll let you know how it comes out. Thanks to everyone. You have been a great help.

I got the Holley rebuilt today. By the way, it was full of trash. Everything seems to good now, except that when I drop the trannny into drive, it pulls the idle way down, even to dying unless I idle it up at the idle set screw. Is there a vacuum line wrong? The only ones connected are the vacuum advance and the PCV valve. Everything else is blocked off.
