About the four wheeler it has been sitting for many years but I redid all the fuel components carbon line filter petcock plug wire CDI box coil but it fires right up soon as I take off and park brake release it dies instantly but if I hold the lever up it runs great but then still dies in like 10 min after gets warm but ordered new park brake switch will update when I get it but some info until then would be really appreciated ty 😊💯💯💯💯💯💯💯💯💯💯💯💯💯💯💯💯

 

Maybe a wire is in the wrong place. The foot switch is only for the start circuit.

 

did you ever figure out the problem?

 

Usually a bad earth to engine. With brake on, the mechanism completes the earth circuit.

 

I've attached the wiring diagram for your reference. Check the ground connections I've circled. This is where the CDI reads the ground and continues the firing protocol. Hope this helps!
