The carbs have no ID number on them, they are three 2gc's, with two of them set up or converted to run as end carbs for a tri power. I've tried all I know to fix the leaking but with no luck.

Kip, Speedway sells the Vintage 2GC conversion bases for the secondary "end" carbs, but they have no idle circuits so they will not work for the primary carb. What exactly is your vacuum leak problem. Are you trying to modify stock bases for the secondaries? There's a lot of extra vacumm port holes in most of these old carbs for various emmission tubes, make sure you have blocked all the holes or you will have a major leak and think it's the throttle plates. I went through a dozen swap meet cores to find enough parts to build three carbs.

I'm building a 3x2 Rochester set right now, and I would like more details on your problem. Eelco has some parts, but no bases, and their extended throttle shafts have been on back order for some time. They do stock jets and gasket kits for 2GC Rochester's.

Techinspector1, good information on the Quadrajet site, thanks.
