I am trying to help a friend get a new car he bought running. It's a 39 Chevy 4 door sedan with a 327 in it. It has an Edelbrock 1406 carb on it, and I cannot keep it running when it is put in gear. I did an online search using the words car stalls when put in gear, and EVERY ONE of them has an edelbrock carb!!!!! The car was bought and driven into the garage, but the car idled really high. I have since gone through everything on it (over the phone) with him since he is Florida. Things I found so far. The 4 and 6 plug wires were crossed, and there was no ground wire on the choke coil. I assume this was the cause of the high idle. So with that being fixed, he got it started and set the timing at about 14 degrees. Now the vac advance was hooked to the passenger side port, though I believe for this car it should go to the driver side. Regardless with the vac advance connected or disconnected, at 14 degrees it should idle. He can idle it at 800 and it is really smooth, the throttle response is really good, and it runs at about 170 sitting in the garage. Now whenever it goes into gear it stalls. I thought maybe it was lean at idle so I had him check the mixture screws and the passenger one was bottomed out. He opened both to about 2 turns but no change. He has raised the idle to about 1100 and tried to feather the gas to barely keep it running. I told him to plug every vac port he could find and see if there was a change. There was none. Only things I can think of is a base plate vac leak, but the car idles so well at 800. The other thing is I wonder if the coil is bad. He killed the battery by leaving the key on, so I don't know if it fried. IF anyone can give me any idea, it would be greatly appreciated. Thanks.
