My son was riding his 50 & it stalled in the woods. He couldn't get it restarted & came & got me. It started right up for me & ran for about 2 minutes & stalled. then it started with full choke ran for about 10 seconds & had to play with choke to keep it running. Cut out & won't start at all. It will crank, but it will not turn over. Any ideas?

 

Thanks for all the help. got it fixed. the fuel filter was clogged
