Finally got around to rebuilding my car's original carburetor, so the rebuilt unit I was using in the interim is up for grabs. Float bowl casting # is 7036159. Regardless of its origins, it worked fine on a 425. 1-3/8" bore, be aware that this won't interchange with 1-1/4" bore 2G carbs. Bought through ebay, can't remember the vendor as it's been a year and a half or so. Opened it up to ensure that the internals are all good and clean. Accel pump is okay as I recall, it's a unit with a hard plastic skirt instead of rubber though so might want to swap it out with whatever you've got, if you're picky about that sort of thing.

Not included:
-Vacuum nipple mounted to the float bowl
-Air cleaner fastener stud
-Small tube insert at the back of the carb for the choke heat riser

These items, I transferred from my original carb to this one, and then back after the rebuild. Also would like to note that while it isn't really necessary, the choke adjustment slot is also chipped, so if you're swapping a carb out with this one, transfer these items over.

Has RTV in the rear near the throttle body, not my handiwork but judging by this thread it is a "fix" for venturi bleed ports in the gasket, which some argue for filling in due to their potential to draw grit directly into the carb, bypassing the air filter. This carb is equipped with a bimetallic hot idle compensator valve, so if my thinking is correct the bleed ports should be unnecessary for this carb (wrong gasket selection by rebuilder or a little bit of factory madness, perhaps). Some may nitpick about the use of RTV but after a couple thousand miles of street use I've never had an issue with this particular application of it, it seems to be well outside of the actual bores.

Anyway, best offer takes it, paid $215 for it myself with shipping etc. Thanks
