New to the forum but have owned a 1984 Honda ATC110 for a few years now.
My 110 was ran into a pond and then set with water in the engine. When I got it I changed the oil, ran it and changed it agian...Did this a few times. Thing still ran great but smoked horribly. I ran it anyway then the plug fouled. I pulled it out and the carbon build up stripped the spark plug threads. Really ticked me off. Well I have it apart now rebuilding the top end. Everything looks great. I noticed a few tiny specs that looks like pitting in the cylinder but nothing that would cause it to smoke as bad as it does. Rings are not stuck or rusted either.
I did a slight hone on the cylinder and im gonna replace the valve seals and all the top end gaskets. Now I need to do something with the head. Heres my question, Should I helicoil the head and still use the 12MM spark plug or just retap the head for a 14MM sparkplug?
