Spark Plug Help???
The spark plug that came with my Chinese engine is marked 'A7TC'. I believe this is the standard spark plug that come with all Honda clone scooter engines of similar 125cc size. I want to purchase an NGK iridium equivalent but I am getting conflicting information of if I need a CR6HIX or a CR7HIX and I am also seeing it is offered in resistor and non resistor. Can someone in the know of all worldly spark plug knowledge help me with this? Thanks
