DON'T TEAR DOWN THAT CARB JUST YET!! I'm with Jerry on this one! Sounds like a fuel delivery problem to me. That "NEW" fuel pump may be BAD. Won't be the first time I've gotten "BAD" NEW parts. Disconnect the fuel line at the fitting going to the carb and put a threaded fitting with a barb into the fuel pump. Attach a rubber fuel line to the barb and out to a container. Disconnect the coil to the distributor. Have someone crank the engine and watch the fuel volume and pressure. That is where I would start.
