June 2, 200422 yr I have a 1996 Gas Gas 270cc and lately after evey ride the plug is fouling quite badly, a dry carbon sooty type of fouling and I dont know why. I am running a pre-mix of 80:1 and the fuel/air screw on the carb is 3 full turns out. Any one any ideas? I have attached a pic of what it looks like.
