new fuel pump is now delivering fuel to carb. I can get the engine to turnover, start and run for about 3 to 5 seconds with no problem. It runs real rough and sputters. Looks like it is sputtering gas or something out of carb when oil bath filter is off. Points are set correctly and when I pull on throttle I can see gas shooting out of the little needle in the carb. What is the likely cause of my problems?
