Hey all. I'm trying to get my ride on the road again and it seems I have a big problem.

Last year I rebuilt my carb at my friends shop, under the supervision of certified mechanics, using instructions from the Plymouth factory manual(I have purchased one of my own since). I bagged and labeled all of the parts and was very careful to follow all directions. When I had any questions or problems, I asked one of the mechs.

Upon reassembling the carb, it eventually started and ran without any probs. I didn't make any adjustments at all. I drove it home 5-10 miles wihout any problems. It wasnt inspected, but I ran it periodically to keep everything from cracking, seizing.....

Each time I ran it, the car got worse. It would eventually start sputtering and when I would add any gas, it would almost stall. Eventually I would let it idle to the point where it would cut off. When I would start it, the same thing would repeat. Eventually, I had to let it sit for hours until it would start again.

I guessed that the carb was running rich and needed adjustment. I asked my mech friend and he said the choke may not be opening up. I ran it to see and it never completely opened by the time the car cut off. I checked the choke valve and the cam and neither will react to the other. There is a piece of linkage in between that doesn't seem to do anything, and I'm guessing that is the problem.

Let me know what you think, and if you have any other ideas. Thanks again for all of the good info. Many of you have been a big help in the past.

Sounds like a sticky or dirty needle valve...
Remove, clean, re-install & test... to see if that solves the problem.

Thanks for the replies. I'll check the needle valve. Thanks Dan. Thats what I rebuilt it from. It is also inside the full manual that I purchased. In speaking with others, the linkage goes to the choke pull-off valve. I also forgot to mention that my car used to idle high when it was cold, then settle down. Now it always idles low, even in winter cold-starts. Anything else that you can think of that might cause these symptoms? Thanks again for your help. I really appreciate you trying to help me through this.
