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.
