Any help. I disconnected the key and multi switch at the plug. I used a screw driver and got it started at the starter solenoid. Ran good idle but would die with throttle. Anyone know what it is. Only thing I can find is that it has gy6 shrt case engine. With forward, neutral, reverse.

I took this off from the white plug

 

I doubt if your running problems are electrical, but get the correct key switch assembly, I guess Extreme Motorsports will have them in stock. Clean the carb out and fit a new spark plug, which should cure the running problem, unless you have messed up the wiring of the electric choke mechanism too.
