Well gentlemen I am sorry I failed to get back to everyone about my Plymouth starting problem.I drained the old gas and rebuilt the carburetor. What I found was the Pump jet was clogged. When I worked the throttle of carburetor on work bench virtually no gas was coming through. Took the rivet plug out and removed the jet and thourghly cleaned. Rechecked with gas in the carb before I put back on car and now it works fine. Let car sit for a few days and get in and it fires right up. Thanks for everyones input.
