Hey all,

So a short time ago I removed my SOS because it was leaking constantly due to a rotted seal. My fuel line is now running straight into the carbs. I sealed off the vent hole and everything seems fine as long as I'm diligent about using the petcock when the engine is off. HOWEVER, my #2 carb seems to often overflow right after I fill up the tank. I have fully cleaned and refurbished carbs with new floats etc., so I know its not a float problem. I have a feeling it has something to do simply with the gravitational pressure of the fuel into the carbs when the tank is full. Is this anything anyone has encountered before? If so, is there a solution?
