I just purchased a new 2020 raytech Chinese 125cc ATV. Already leaking fuel from the drain line. The float in the carb seems to be stuck. Can anyone help me find a replacement carburetor for this quad. Ty.

 

Just un-stick it. Either the needle or float will be stuck with some protective oil left in the carb, or some dirt has jammed between needle and seat. If there really is a manufacturing defect, your supplier should send a new carb, but it will probably be a Honda clone engine, so require a Honda clone carb, hundreds are for sale on eBay etc.
