I've gotten a lot of good help from this forum and hopefully you guys can come through again, because I am at a loss. I apologize if this post is long but I want to make sure I cover all the info I can. I have a 2wd 1987 Ramcharger with a 318. Ignition was changed from lean burn to a orange box ignition that came as a kit with new distributor, and with the help of the forum is working great. I had the ramcharger taken to a shop to run new vacuum lines as there were some major vacuum issues. Transmission seals fixed. And a new carburetor, as the original 2bbl holley was shot. Carb was replaced with a rebuilt factory replacement. The shop sent it back because they claimed it was bad and caused the engine to bog down. Second carb that came in they claimed the same thing. Third carb came in and they said it was good to go. I come pick it up and its running great. However after about 3 miles on the way home engine started bogging down/stalling and died. Coasted to the side of the road and it immediately fired back up and after about a mile did the same thing and died again. Finally got it home and after I turned it off it would not restart and I could strongly smell gas, and I assume it flooded. After sitting for about an hour I went out and it fired right up. Took it down the road and it ran perfect for a few miles then started bogging and dying again. I called the shop and they said they stand by their work and will get a new carb and replace it at no cost to me, however I am worried that 3 bad carbs in a row seems a little unlikely. Any suggestions that I should be looking at causing this problem, rather than just doing infinite carb swaps, or are the "professionally" rebuilt carburetors really likely to be that bad?
