You might need a new spark plug, or a new piston kit, try gettin the plug first, it worked for me. You can also ask the people from moped warehouse, or heeters.

Wouldn't hurt to include the circumstances either. Cold, Hot, fast, slow.....benny, you get the idea.

take off the cylinder head then take out the cylinder. decarb everything, including the top of the piston that hits the plug. make sure your exhaust isn't clogged, as well as the exhaust port on your cylinder. Do all of this, then post back if that doesn't fix it. Could be a timing issue if that doesn't work.
