The problem of having gasoline leaking into the intake valve, causing a rich or flooding situation is for a scooter is one that shouldn’t be avoided. In fact, anytime you experience problems with fuel, the issue should always be discovered and a solution provided to reduce the potential of further damage to the engine or void any warranties.
For the most part, this problem is caused by a carburetor that has a float that is stuck or a clogged jet that is continually flowing fuel to the intake valve. If this is the case, simply cleaning a carburetor can be an easy solution.
Posted below are instructions on how to clean your carburetor for most scooters sold through Variety Powersports:
To clean your carburetor you will need to take the carb off the scooter. Typically there are 2 to 4 screws on the bottom of the carb you will need to remove.
After removal, make sure you have clear access to the float bowl and the carb jets. The jets look like two gold screws with holes in them. Unscrew the carb jets and make sure nothing is clogging them. Your float is usually white and you will need to make sure it moves up and down freely.
Clean the bottom inside of your carburetor and the bottom of the bowl with carb cleaner and this should remove most of the debris.
Reassemble your carburetor, reattach to the scooter, reconnect all hoses and cables and test fire your scooter to verify there are no leaks.
