Re: where can i get a spark plug for my 49 cc china engine kit in syores?
R is for a resister noise suppression plug. The lower the number is in the title with NGK spark plugs the hotter the plug runs for self cleaning. If you do any thing make sure the plug clears the piston. Turn the motor over once don't start it at first. It should look thread depth wise close to the plug you had.
Still gotta have a since of humor.
