As some of you may know, I am the one that knows little about the finer workings of the old Model A. So I always have lots of questions.

Being bored in these winter months, I decided to try my hand and rebuilding an extra carb. Well I got all the main pieces I needed, upper and lower bodies and ordered new parts from one of the vendors and got everything put together. Put it in the old coupe, was surprised it started, but the old rig just did not run well at all.

The problems: 1) it is running to rich. Ruff running with black smoke out the tail pipe. Turn the GAV all the way in but does not make any difference. But I did find that I needed to put in the little fitting in the GAV hole. Put this fitting in, started it with the GAV all the way in and still the same problem
2) second problem is that when I take it out for a drive, when I press on the gas, the carb backfires and it almost quits. This does not make sense based on problem #1 above.

So what am I doing wrong? Do I have something plugged up somewhere? If so where" Do the upper and lower bodies I pickup up have a problem in them somewhere? I did use all new parts for all the things that can be changed in the carb. I was thinking that I should swap out the upper and lower bodies with a known good one. This may be my next step. Bought the new parts from one of the best suppliers in the industry. Please help this old bored guy.
