Why is fuel leaking from the carburetor on my generator?
On my generators I turn the fuel off and run the carb out of fuel for several reasons the first being a tiny pice of crud in the seat for the float valve would be impossible to detect in most cases even my Onan will leak like this some times so it’s a good idea to turn off the fuel, reason #2 when fuel is left in the carb the methanol eats up some of the seals and absorbs moisture, while doing this debris from the degraded rubber parts and fuel lines cause leaks. It is a good idea when done running your generator to remove the load and turn the fuel off letting it run until it dies this helps keep the carb clean and the only negative is you have to open the fuel valve and wait a minute for the bowl to fill up prior to starting. This also provides some additional cool down time for the alternator.
