Re: Sudden Engine Cutout During Warm-up??

Good looking car!

That exact thing happened to me - 3 pieces of wood in the tank. They would plug the intake, the car would die, I would pull over, I would start the car and drive. Over and over again. Took the tank off (relatively easy, had to rebuild the bolts that hold the tank) and had it professionally checked at a radiator shop.

If you want to bypass the tank and see if the fuel system is the problem, use a marine tank designed for boats and a 6v fuel pump, or gravity.

There's a choke on the carb that is based on engine temp, it may be malfunctioning. I'm no expert, but if you have a screwdriver in the carb after it starts keeping the butterfly valve open, does it help?

6V positive ground, right, with large (1AWG) battery cables that are well connected to the starter and the block?

The flexible fuel line to the fuel pump in good condition? The diaphragm in the fuel pump is subject to new fuels that eat the older materials, you may want new diaphragms installed. In the Packard Directory in the Main Menu is several places that rebuild fuel pumps, or sells you kits to install yourself.

Is the fuel clean? No water? Is it old fuel?

My dad once demonstrated how good exhaust systems, that don't leak, can kill an engine by simply putting your foot over the tail pipe opening.

Is the coil clean dry and the cable in good condition? The distributor cap clean and has no cracks? It does sound like a coil problem, check the wires that are attached, and the connections themselves. Like mentioned above it may be the coil, a simple fix.
