Still having problems, but here is a good clue:
Went shopping yesterday - very hot, shops are about 10 miles away.
Done shopping, car started up no problem. Drove around parking lot to the main drag. Waited for an opening and pulled out. Then seen an SUV barrelling down on me so I punched it. That's when it momentarily stalled but then kept going but engine cutting in and out. Turned on back-up electric fuel pump and got home no problem. Very scary and annoying.
Can I eliminate the float bowl drying up when I was shopping because it started up first try? I'm thinking of the heat under the hood because tightening up the manifold nuts didn't help the exhaust stink and I'm thinking maybe blown manifold gasket.
Could it be vapor lock in the mechanical pump when it was sitting? (I've taken this pump apart and the diaphragm is in A1 condition)
My next step is ordering up a new gasket and a later mechanical fuel pump and spacer - unless I can narrow down the possibilities.
