Gotta 1999 Polaris 300 two stroke 4x4 .. running fine then at 3/4 throttle in 2 wheel high it just quit and then when I tried to restart by electric start the starter would not turn motor over so I pulled recoil starter cord and it wouldn't budge til I gave it a good yank. Turns over sound like its got compression but wont run has fire and gas. If any one could give me some info or just their input would be appreciated . PEACE

 

Check compression if you can first. Must be at least 120 psi or more. From your description sounds like you may have had a piston seizure. If compression is at least 120 psi,have spark,then could be fuel related.
