weird cutting out problem

A lot of carburetor cars are doing this now. It is do to the fuel. The way to get rid of this problem is to run a fuel return. If yo check any 87 mopar last of the carburetors. They have three fittings on the fuel filter. The one is a return this keeps newer fuel from coming to a stand still under pressure and vaporizing and allows the floats to keep working properly. The reason your car starts hard is do to flooding . when you rev it the fuel starts moving and the problem goes away. Depending on what year your car is you may be able to utilize your vent system and add a fuel neck vent from a 70 back. If you need help doing this I can give you some info and have fuel necks.

I have had this same problem with cars that have had pumps replaced with later units. This has become an ongoing problem. Newer pumps fit older motors but are made tor returns of the newer cars Keepping the fuel moving prevents this from hapening. Steve
