My experience with a leaky carburetor is on going. I think I have tried every one of the float shut off valves offered by the parts suppliers. I have not found one that works 100% of the time. The float valve is the primary cause for a leaky Zenith. Sometimes it works perfect then it will leak. It even will leak sometimes with the gas shut off. I am presently adding some Marvel Mystery oil to the gas as a way of providing some lubrication to the valve. It seems to have reduced leaking but still not 100%.
