97 has spark, fuel, compression, air but won't start

[keiken01]

I have a 'new to me' cart that has been running great then all of a sudden it just stopped. I was driving through some tall brush the other day, but normally it's just driven on grass.

I turn the key to on, press the pedal and the engine spins, the air passage is clear, the fuel pump works, the spark plug is sparking and I have compression.

I even tried using starting fluid, but no luck.
It acts like there is a kill switch that is preventing it from starting.

Thanks for your help!
