I have a Kazuma quad 50 my kids love to ride. It was driving fine then it stopped running and carb over flowed.
replaced the carb and changed spark plug and oil and it still does the same thing.
barely starts for a second then stalls like getting no gas.

when I check plug again it’s got black on plug but no gas it seems.

not sure what could be the problem.

Anyone else had this happen ??

any help appreciated
thanks.
