1950 Windsor weird driveability problem
Posted 19 October 2012 - 11:18 PM
I've done the following:
checked for vapor lock by removing gas cap. Still does it
removed air cleaner. still does it
rebuilt fuel pump. still does it
checked fuel pressure. 12psi
checked fuel pumped volume. normal
Pulled top off carbueretor. fuel bowl full (float is set right!), float dry, cleaned up interior of carburetor, blew through jets, etc. Still does it
The engine starts easily and idles smoothly, pulls fine on hills (except when 'acting up'). Nice hot blue spark.
I'm completely baffled. Have any of you encountered a problem like this?
Thanks in advance for all replies.

Is the flex hose at the fuel pump new and of modern rubber?

Can you tell me any more about the "Oilite disc filter"?
The flex hose is NOT new, and a good suggestion that I hadn't considered. Duh! I'll be checking that out tomorrow.
Again, I thank you.

You could mount some kind of small 1 gallon can or jug and bypass the line from the tank going directly to the fuel pump. That would tell you if the problem is before or after the pump.

The answer was, a broken wire on the distributor plate. The wire was broken inside the cloth wrap. It looked fine. It would make some contact to get me going but eventually would quit, usually under load. I would get towed home and then it would start right up again and I could drive it into the garage. I believe as the vacuum advance would move the plate which would move the wire. The wire would vary its end to end connection with the flexing.
I found a NOS distributor plate with points and condensor and put it in over the winter. The car ran stronger, smoother and never failed.
That is my suggestion.

The pressure is controlled by the spring behind the diaphragm. Suggest you replace the spring or add a pressure regulator.
