What do you have for a choke? Carbon on plug has to be too much fuel/too little air. Is the choke fully open? Is the air cleaner clean and not restricted, acting as a choke?
If you pull air cleaner off the carburetor and run it, does it still carbon up? If it does, check the other end, see if the exhaust could be restricted. ??? Id exhaust can't get out, fuel loads up in the cylinder.
Ok,Thanks let me know.
