ok so i got this TNG LS49cc moped from my friend it doesnt run but i got it for 50$ i was wondering if any of you guys had any idea why its not starting. the piston is turning over but nothing seems to happen iv got the right spark plug and took the carb apart, how do i check for if a spark plug has spark. im kinda lost in this but hope i get it going, i tried posting this on a moped forum but there all dumb as s**t and talk down and arent as cool as CC so i would see if anyone knew anything on here about it. thanks again guys
