Carb Problem
I have a Carter AFB and today I noticed that the passenger side primary venturi has gas dribbling out. I suspected carb problems the last time I ran it but didn't pursue it at that time. The car stalled out and would not run well which now makes sense. The car is in the process of a body on restoration so it is not being driven. Is this a stuck float or another rebuild. Thank you all in advance. Almost done with the primer/build coats so paint hopefully will be soon!

Sounds like the needle/seat could be gunked up. These carbs are very easy to work on and rebuild. If your comfortable working on it, get the S/A book on AFB's/Edelbrock carbs.

S/A Design are books like the HP Series that David Vizard wrote. They have titles such as, How To Rebuild the Small Block Chevy, Small Block Ford, Mopars, Tuning and Modifying Holley Carbs. Really useful text. This particular book on the carbs is authored by Dave Emanual.

Here is a picture from my 59 WCFB before I replaced the fuel tank last year (which applies for your AFB as well). Notice the fine rust dust (brown areas) that eventually clogged the floats.
See what you find when you open the carb. With this one, which I had rebuilt previously, it just required a quick cleaning and adjustments check and was returned to service without a full tear down and has worked perfectly ever since. If you have never serviced the carb, do so, the newer needle and seats are better. Then decide what items upstream in the fuel system to service as well.

Well, the primary metering rod was bent on the passenger side. I don't know when it happened but had to have been recently since the car was operating fine. I straightened the rod, made sure it had smooth operation and put the top of the carb back together. Thank you all or your input.
