My Scrambler want start. It has spark and when it does start it barely stays running and i just fixed it. I had it bored out 20 over and new rings and everything. i called my local atv dealer and he said the spark plug might be filled out again and it only has a half in hour on it. do u thinks it the spark plug or does it need a hotter plug please help me!

 

Middle....it could be a number of things....if it starts but doesn't want to stay running, it could be your spark plug or spark plug wire, clogged or mis-adjusted carb, air filter dirty, or a variety of other things. You will just have to do a little bit of trial and error to find the problem. I'm not there,so I really can't tell....sorry....I hope this helps anyway.
