spark plug carbon fouling, for Honda 110 ATV

Recommended Posts

I can only use a single spark plug about 8-10 times before it becomes so sooted. Which results in it not firing. I have had the head gasket replaced, lashed valves and rebuilt carburator. If ANYONE could offer suggestions or seen this problem before I would be open to any suggestions you might have. Thanks.

Are you burning oil? Any smoke out the exhaust. It is either that or you are way too rich on the jetting.

The older Honda ATC's would get worn float valves. This would cause fuel to run over and richen up the mixture. The 185s and 200s did this as well. You should check yours.
