FYI on carb floats
I have been hearing more about sunken floats. If you have fuel venting, a rough running engine or a tough time syncing carbs check the floats in the carb bowl with fuel in them. The floats should ride even with the small metal pins sticking out the side of the floats. If the pin is down under the fuel and or one float is lower under the fuel level compared to the other you need to replace the floats. Do them in pairs and not a single float.
