I was just wandering if my snowmobile is junk or something miner to fix. The boy was riding it last week and it died . Then you couldnt pull the rope to start it. I turned it over by taking the plugs out and turned it over backwards till it freed up. sounded like a grinding sound .. When it freed up Pulled the rope and it fired right up.. drove for a few feet and died the same thing .. but freed right back up .. Any suggestions ? Thanks
