Wont start , n when i push the thotle it turns off what can i do ??

Check oil level capacity, to ensure in specs. Check spark plugs, ensure its clean and correct plug for your quad.the only other could be is ign coil breaking down when warm. Check fire at plug when this happens. First ensure oil level is correct. Make sure your electric fan is on when bike is warmed up.

Try to push start hopefully you know how if not have someone push you I would use a car only need to go like 5mph make sure your in first gear holding the cluch when you get up to speed let go of the clutch it should pop start up if not then check the starter or check any wires you may not have on proper

clutch burned up...sounds like it. pull the clutch cover off and inspect it.

take carburetor apart and do a good deep clean. also check valve clearance.

clogged choke jet or passage for sure.

sounds like your rings are worn out.

is it in nuetral?

check battery u may need a jump or the oil is too cold and 4 wheeler needs to sit in a warm place for a hr or 2

Check the choke or motor compression.
