Jim,
My car does not have chokes, so we can put that one to bed. I do agree
that it should clear out the fuel pump a lot quicker, but it definitely acts
like fuel starvation. The only thing I can figure out is that the hot air of
the motor rest under the hatch and heats the fuel pump. If it were a carb
issue it would not start when hot.
I was thinking of doing the Mr Gasket 12S fuel pump and Summit SUM-890145
inertia switch. The fuel pump is a 4 to 7 lb model. The inertia switch
looks like a copy of the Ford inertia switches used in the 90's. Let me know
what you think.
Adam, you want the 42S pump, not the 12S. The 42S is rated at 2.5 to 3 psi
and works great with either Solex carbs, or Weber ICTs , and without a
pressure regulator. : ) I'm running that pump on both of the above sets of
carbs. I went with them on my 65 Notch after having 2 mechanical fuel pumps
vapor lock. Granted, I'm running an all aluminum engine case in that car, and
the case likes to hold heat.
I hope this helps.
