So I got this free carb. It's a Holley 2 barrel, and it's a clone of a Weber 32/36 DGEV. It came off of an old AMC Jeep mail truck converted into an ice cream truck. I thought for sure it was a 5200 carb, but in more research, I found there are 5210's, 5220's, 6520's, etc. I was wondering if you guys could help me identify it so I can rebuild it and put it on one of my Hondas.
So there's this little thing that the 5200 doesn't have, and as far as I can tell, it's the only thing different between it and the 5200. I don't even know what it does. It's not in ANY diagrams that I could find. It looks like some sort of diaphragm, that maybe you hook vacuum to? I'm not really sure, it connects into the float bowl, but I don't know what it does...
Here it is with the cap.
When you take the cap off, here is the diaphragm.
This is the diaphragm removed.
And you can see the extra 'divot' out of the float bowl under where that diaphragm sits.
And also the difference between the main gaskets. The new 5200 rebuild kit came with the one on the left.
The thing is the rebuild kit also didn't come with a new diaphragm for that, like it did the other diaphragms.
This is a tag that was screwed onto the carb... Googling then numbers came up with nothing.
So I guess my questions are:
A) Anybody know how to identify this carb? I can't find anything online...
B) Anybody know what that thing is in the picture that makes this carb slightly different from the 5200? Can I just cap it and call it a day?
