We have diagnosed that the problem with the B was that it was running to rich. Feeding WAY too much gas. (We got 70 miles on the last tank. So, we have added a fuel pressure regulator and it really made the difference.
Question: Any ideas what the settings should be? How much pressure should be going to the carburetor?

And if it's one of those "pretty" dial-0-matic ones, be prepared to replace it with a REAL one (Holley) soon. Tony meant 4P.S.I. ~MAX~, BTW. better 2.5~3.0.

OEM pumps had an output pressure of 3.8 PSI.
