'51 Won't stay running

Took the '51 200 out last weekend. Started to run rough (sputter/stall). Then it just quit. Now I can re-start it, but it will only run about 10-15 seconds, then quit again. It doesn't matter if it idles, or if I rev it.

Took the carb apart last year, cleaned it and installed a new carb kit. It has been running fine up until now.

Thinking it may be the fuel pump, just filling the bowl then quitting. Or maybe the electric choke is malfunctioning. Vacuum problem?

Any ideas?
