Stop in for a cup of coffee

I have had a few pourous castings over the years mostly with Rochester's. If they have been rebuilt a few times the acid eats the coating off to the bare metal. It is uncommon but it happens.

ah ....I see

wow I have not seen a Rochester quadrajet for awhile now.

In school they taught us "carburetor theory" and used a dualjet to demonstrate.

I think I caught the last of that because they didn't teach much of carbs then and now a few years later they don't teach carbs at all.
