    reading over this thread, I think I see where the problem might be.

    I don't get the reasoning for two fuel filters, but if they are in the vertical position, between the fuel pump and the carb, you have two potential "cookers" that if they are near the manifold, or even the radiator hose, either one could create a "bubble" before the carb once you use the gas in the bowl, that's it till the bubble gets sucked thru.

    I just put an electic fuel pump on the Wildcat which should eliminate that potential, but I am going to move the fuel filter to the gas tank side of the pump, and wrap the fuel line in the engine compartment where it passes by the exhaust manifold.

    the Carter has a filter on the gas inlet. I think us guys with the 50 year old Buicks are more concerned with keeping sediment that has formed in the gas tank out of the carb.

    I've found two problems that are related to the older cars that cause hard starting; one: the accelarator pump plunger is brittle and leaks the gas back to the gas tank, and two: the gasket on the gas cap is dry and brittle, and leaks the pressure that keeps fuel in the line/carb.
    both easy fixes; the carb rebuild kit is about $25, gas cap $15.

    I made the plates to seal the hole in the block where the mechanical fuel pump attaches and made the gaskets. I had a hunk of 1/4" aluminum laying around.

    I don't like this first electric fuel pump that I bought, ($40), it doesn't shut off when the fuel pressure reaches the fourr pounds it's set for. I am gong to wire it thru the oil pessure switch, so it cuts off when the motor isn't running, even tho the ignition key is on.

    I often try to figure out why our grandparents didn't have these problems; one conclusion - they didn't have the traffic jams we have today, plus, they weren't in mile long parades, showing off their cars

    One more possibility

    I spoke to a friend the other day about this (because the same thing happened to me on Saturday night).

    He told me to check the rotor for cracks because when it heats up, it expands (I would think contracts but what do I know). He also said to check for oil in the Distributor. If that is the case then you need to check your O-ring where the Dist meets the block.

    I don't think either one of these is my issue but thought I would share it!

    Resolved my new problem......

    The wire on my Pertronix Ignitor inside the dist was frayed and shorting out. Taped it up and it runs lioke a champ.

    Can't wait to see what happens to this car next!
