I have a 2000 scrambler 500 4x4 and i am selling it tomorow. I had the thing runnig fine this morning., but when i cmame home for school it would not start. I have plenty of gas and the battary is fully charged. It backfires alot and it just wont turn over. Do u think it could be the spark plug? how often r u soposed to changed those? If u guys have any ideas of what it could be please sned a answer. I do not know much about fourwheelers if u couldnt tell. Hurry

 

Check the gas tank vent tube. Make sure that it is not kinked.
