checked the pilot jet, drained the gas, put in new gas, tried a new plug and it still doesnt want to start.if i manage to get it started it will run for a minute then die.

 

You say what you did, but I am wondering what started it all. Did it set for a long time? Was the gas gelled? More info please.

 

it was running fine for her then she says she stopped and it died.then she started it with the choke on then drove it to the garage.the gas seemed fine but a guy at work said to drain it anyway.

 

Heres the problem.
You have three major systems that need to work to have an engine start and run. Mechanical, fuel or electrical.
Mechanical is usually on or off. In other words, if you break a cam chain it won't run, even for a little bit. That Leave the other two.

If this was my problem, after the engine quits, I would turn the engine over for about 15 seconds or so and then I would pull the plug. Does the plug have fuel on it? Ground the plug and turn it over again. Do you have spark?

These steps I have outlined will tell you which system you need to go after. Could be something as simple as a plug that quits fireing after it gets hot? Could be a vent problem on the gas tank or carb that will not allow the fuel to flow? Petcock plugged?

These steps will show you where to look first. It's up to you to find out where the problem is.

 

Like Doctorturbo said. It is most likely fuel, air or electrical. I wouldn't think a quad that new would have the electrical system malfunctioning so soon, but you never know. Had any work been done on it before the problem started? Maybe something came loose. Check for loose or damaged wires. If it is getting too much or not enough air it might act that way. Clogged air filters or something sucked into the air intake. It is harder to check to see if it is getting too much fuel than it is to tell if it is not getting any. Make sure the choke is functioning properly. Also is the new plug gap set right. How did the old plug look when you took it out?
