Re: where can i get a spark plug for my 49 cc china engine kit in stores?
I use NGK (3922) BR6HS because i have a speedo. I get them at the local auto parts store. While your at it you should replace the spark plug wire also. I think its 8mm? Search it you'll find a link that tells you how to do it. A good plug and wire make a huge difference. Sometimes the auto parts stores cant find the spark plug under the manufactures number so just use the four digit number.
