I am pretty new at fixing my atv and it really shows. I cant get it to start i check the carb the fuel lines the battery the plug notihing and I"m stumped i can't figure out why it wont start and the other thing how do I get the rear axle off i ride a 2004 ltz 400 if any one could help that would be great

 

Whats it doing when you try to start it?Is it turning over? is it compleetly dead?have you tried pull,or push starting it?Do you have spark?
