Hello Everyone...It's been several years since I rode my 4 stroke. (I'm riding an electric one now). Anyways I decided to wake it out of hibernation and changed the plug, removed the carb, blew it out with compressed air and shot carb cleaner in it. It idles just fine, but once I go WOT it dies. I've been reading various threads about drilling out a brass plug but am confused as to which one since there were no pics posted. I have 2 brass ones on my Huasheng. Which one should I drill out? The left or right one?
