I have a wiring diagram I can e-mail you. E-mail me off group and let me know if you want it.
As for the running issues:
Poncho is right. It won't run backwards.
Shutting off after a short time could be a coil, fuel feed problem. Check for spark after it shuts off. If no spark, it may be the coil or points problem.
Check for fuel after it shuts off. Remove the fuel line from the carb and watch how much fuel comes out. The stream should be steady.:goodl:
