depends, if your fouling them right away it could be your jetting is too rich. if theyre fouling after sitting for a long time its probably just because theyve been sitting a long time.

Generally it is because your jetting is too rich. This is essentially when there is too much fuel coming in to be ignited, it wets the plugs and prevents them from firing. But there are many types of fouled plugs. You could end up with a large amount of carbon buildup (possibly as a result of highly leaded fuels), you can foul plugs from running too rich of an oil mix ratio (ie. 20:1), many different things. But again, probably the most common reason is due to overly rich jetting.

To rich, poor spark, or wrong plug heat range.

no offense 6speed, but it could be the operator. shee's like to scream and if you're to easy on her, she'll choke on you instead. :yank: outside of that, mixing rich or jetting. B)

Just as a side question, i've heard of plugs on automotive (v8s and such) engines fouling from excess heat. Is this even a possibility on a 2 stroke or will the rings go before you get a chance to overheat the plugs?
