I had a problem similar to this and since it runs for a short time then
dies, it must be fuel related..the length of run time depending on how much
fuel was in the carb bowl. Sudden acceleration of course-requires a good
shot of fuel from the carb.
My 56 work truck would run, mostly short runs, and then stumble and
die-just as yours. I replace my filter, pump but still had the same
results-dont forget their is a fuel filter sock on the end of the pick-up
tube inside the gas tank. Now all this is on a truck that has never been
restored and is pretty much used around a farm and only gets worked on when
it doesn't work.
The problem was found to be in the fuel line from the tank to the pump, it
was clogged from all the rust deposits from the tank itself. If your truck
has new lines then ignore this entire email. I put an air hose to it and
would barely flow through the old line--a quick replacement and things are
fine with it now.
