Wrong spark plug?
Ok while I am still frustrated about my problems with the Komoto 250 Chinese quad that I bought I am still not ready to just let it go. I noticed something about my spark plug that got me thinking. The manual says the correct plug # is a AT7C and when cross referenced with NGK it says the plug has a 10mm thread and is 1/2 inch long. The plug that came in the quad is a D8TC which cross referenced says the the thread is 12mm and 3/4 inch long. Could this be causing all my problems? Maybe the extra 1/4 inch of threads is going too far into the cylinder head and not firing correctly? Is it possible to even go back to the plug the manual states to use if in fact they used a 12mm threaded plug? The engine runs very very hot when it does get started then the surging issue also happens just thought maybe if the wrong plug was put ii could it cause the problem I have been having.

WatzupDog,
Your comment was indeed equal to free, for it was of no value... And uncalled for...
The price of a quad does not nessasarily indicate its value to user. I have two Kazuma mini's that have served their purpose well with little problem in the last year in a half... Yet in a thread that exists on this forum I and serval others are having problems getting the New Suzuki Z50 to go past 15 MPH with our 6 and 7 year old boys... Should I feel that I got my moneys worth???
Crewcab,
I have nothing to offer on your problem but I wish you luck in getting it resolved.
