I've never had this carb in my fat paws, but just looking at it as mounted all I can see is a "14" cast on the side facing the left fender. From other posts I've read I'm guessing it's a Holley 2 bbl. Anyway the bottom section is always wet, and I noticed today that when I pump it, gas drips on the back side near the throttle linkage.
Carb is all clean and shiny and I was told it was rebuilt.

My questions are: Does this sound like it may be a holley? Where would it be marked? Why does it leak when I pump it?

I'm also wondering how to set the idle mixture? I've read that you can set a single barrel with a vacuum gauge to get max vacuum at idle. How do you do it having 2 bbls to deal with?

Finally, after this I'll shut up. Does anybody know where I can get a carb spacer (insulator) for this 2 bbl?

Thanks
