1979 Harley Davidson golf cart with New Points. Brand New Carb. New Coil. New Fuel. New Fuel Filter. New Spark Plug. Spark plug & points gaped correctly. Compressions 100+. Timing Is Correct. Yet it only sputters every once in a while, with choke but won't start. How does this make sense? I don't know. I have the same question. Any replies would be greatly appreciated, kind of stuck in a rut.
