New here I got this sweet little 90cc utility quad and the carb was leaking the bike would start and run great for 10 to 30 minutesthe just die well my neighbor told me to thump the carb a little and it could stop the leaking possibly. Well I also pulled the plug to see what was going on. My spark is all wacky sometime it only fires right when I let off the starter or it will just spark randomly. Where should I start? Clean the carb or get a new one? And test the coil and cdi or just replace?

 

Tough call here as many have issues with these cheap little imports. Not much backup information or parts can be really tuff to find. In my area we have some dealers that promise you the sun moon and stars until after you purchase the bike, then they are no help at all. They all want to blame it on the importer....so good luck, you may want to try posting in the Chinese quad section and mabey get some help there.
