The tank is plastic (36 gal) also there was no hint of rust, or dirt when I cut the filter open.

 

[QUOTE=blackvan;3157043]Its generally called a Carter BBD, I found rebuilt Carters for your vehicle at Rockauto.com for $142 + core.

These videos may be helpful.




So, even though it doesn't say BBD on the carb and no where does Rock Auto list 0-2681, you think it might be a BBD anyway?

 

[QUOTE=arthur1920;3157193]Yes. Carter BBD carbs were used on Dodge vans of that era.

BBD is a general model type so its like saying "thermoquad" or "quadrajet", its a general model type but you can't just swap in some random version. This model type was installed in many applications so many variations exist. I posted the videos so you could compare yours and decide for yourself if the carb you have is in fact a Carter BBD.

I think the floats and/or needle valve have failed resulting in too high a fuel level in the bowl. But that excess fuel should be overflowing and spilling out the bowl vent rather than leaking through the body gasket into the venturi as you described.

That is why my first assumption would be warped casting or damaged casting though it could be an incorrect or damaged gasket. Replacing the floats and needle valve won't solve that. Personally I'd take it apart and check casting for straightness or damage before spending any more money on parts. Otherwise just buy a rebuilt and be done with it.

I've seen warped body castings on almost every make of carburetor (weber, carter, autolite) and in my experience its pretty common.

 

IMO, if it were a damaged and leaking casting it would be flooding "all" the time I would think.
Never the less, carb needs to come off to repair or replace. Need to start wrenching. Let us know what you find.

 

OK. I took it over to the mechanic who rebuilt the carb. I expect some consideration as this is his second shot at the same problem.

Thinking about it. I am expecting it to be the float since that part does not come in the rebuild kit AFAIK.

Will keep you posted.

 

finally got it back with new carb kit installed. Seems to be working ok, fingers crossed.
But, I should have done it myself...faster not to mention cheaper.
