Many off road bikes have a hose on the cap to vent air in without spilling gas on the rider. Both the drain hose or the vent tube is not critical to the bikes operation. If your float is sticking it will leak gas because after the bowl if full, the float shuts the gas off just like the float in the back of the commode in your bathroom. I would remove the carb and clean it and blow out the jets that deliver the gas when the needle is pulled by the throttle cable. If it is more then you want to take on, I would take it to a motorcycle repair shop. Now your son is interested, he will keep after you untill you get it running, I know that is the way my kids were
