I have a 2003 arctic cat 250 4x4. Ive had it since it was brand new and never had a problem with it until recently. It acts like its not getting fuel unless you squeeze the brake lever or the foot brake just hard enough to turn the brake light on. As soon as the brake light is activated it clears right up and runs like it should. If you release the brake it starts missing real bad. I think its a bad ground somewhere but i cant find any loose wires or any broken wires. Has anyone else had this problem?
