I have a 2004 Warrior that will not run. First the throtle cable was bad change that and it ran for five mins. and quit. Then I found that it was not getting spark so I replaced the plug, plug wire, coil, stator, pusor coil, and then the cdi which gave me spark. It was a aftermarket also didn't think it would change the timing or anything but now it will not fire. It just turns the engine and back fires I get puffs of smoke out of the intake. It will rumble once or twice at that is it.

 

Is it the possibility that the parking brake is interfearing?? Try tighting up the cable on the bars.
