I hope someone can please help, I need to find the right replacement NGK plug for my 250cc watercooled 4 stroke Tao Tao atv.
I took the plug that was in there out and no markings on it.  Please Help!  

does it have the 13/16 spark plug?  or the 3/4?

if it's the 13/16 the ngk b8es should work just fine, or you can also use the ngk br8es br8es is better

if it has the 3/4 plug then use either the ngk d8ea or d7ea

however the chinese atv companies do use weird cheap plugs, so make sure that the threaded area and electrode of the plug you buy is no longer than the one that came out of it.

any of these i have suggested should work just fine depending on the size of the threads.  

Thanks again Wolf1, I'm off work the rest of the week I'll give it a try.  It's great to be able to get the help you need from someone like yourself.

Thanks again and I'll get back to you to let you know how I made out.
