300xrx problem Child
 

My 300xrx is. New buggy 22 mile on it but there is problems it will start up for five minutes then shut off when I started back up it's hard to start and the exhaust starts to glow red radiator fan all that seem to work properly The cart is still under warranty so they're going to fix it I sent the carburetor back for them to drill out the main jet and there going to do something else to it but I'd still like on other opinions I want to go maybe thank you

Not sure as to what your saying, but if the exhaust glows, the engine is running too lean.

Yes Thas what it is the exhaust is glowing red I don't see where to put a picture in a trend I would

It's too lean like said before.
