plugs

[honda200s]

i have a 200s with a 200x carb and a 110 jet and modified airbox . i keep fouling plugs, any ideas? It is not smoking! i just cleaned carb again for the second time this month popped a new plug in ran it for about 10 minutes and came back and pulled plug and it was black with carbon. what can i do to fix this problem? what is the amount of turns for bottom screw? could that be my problem? should i run a hotter plug? im going nuts trying to figure it out? should i go back to my 108 jet and see if that helps? I know people on here run the 110 and dont have any problems!

Have you adjusted the airscrew on the carb? Try going to a smaller main jet if the 108 doesn't work.:D

how new is your air filter? try it without it in non dusty conditions for s very short time, see if it still makes the plug black.
