Did anyone have this problem?

When I start up our 50, it will fire and then die right away.
I put in a new plug. I made sure the gas was flowing since they have the automatic petcock thingy.

If i hold the starter, it will fire...die...fire...die sort of in a pattern. Could this be electrical?

The carb doesn't dump gas out the overflow so I don't think the floats asre stuck. Could it be that crappy electric choke? It won't run with it plugged or unplugged.

Anyone have suggestions before I start buying pieces that I don't need!

I'm going to put a 70 kit on it and figured I'd tear the carb apart then...anything to look for?
