    Unless this is an older 2-cycle that runs with "flat tip" plugs, you have the wrong plug in it.

    Most newer 2-cycle units run with an extended-tip plug, such as the Champion CJ8Y, NGK BPM8Y, or the Autolite 2976.

    Gas for a 2-cycle will usually only be a problem if not mixed when you bought it, or it's really old (most mixes have stabilizer in them).

    You could have other problems - blocked spark arrestor or muffler port, clogged air filter, even wasp nests in your muffler's exhaust.
