i have a 1995 xlt sp that fouls the mag side plug when you start it. after it warms up and you put a new plug in it is good for the day. i was thinking jetting or a weak spark on that cylinder[:p]

Could be a stuck choke also.

I have had many strange things cause this. One was the cap on the carb for that cylinder was loose. Another that comes to mind is the needle and seat or float level. If the choke was stuck open it wouldnt get better when warm.if it was stuck closed it wouldnt foul the plug. IMHO.
