Not having much luck getting started this spring. Finally got up to do a few circuits, felt good. I could smell fuel so I brought her in and found fuel leaking from about half way up at the linkage point. Flooding? Was running fine but fuel was dripping. Really hard to say from where but dripped from the bottom of the carb not the vent tube. Still need to do the carbs as part of the five year rubber. might fix it.
any ideas would be appreciated.

    Hi Tim,

    My bet is a sinking float or the float arm just needs adjustment. Should be an easy fix.

    took the bowl off, doesn't seem to be a sinking float. How do you adjust the float arm. seems to be intermittent. Thought it resolved itself, ran fine for about 20 min then started again.

    You can't always tell if a float has sunk enough to cause a fuel drip from flooding as it may be in the beginning stages. If the pin is down under the fuel level then yes it can be seen without any problem. The best way is to just weigh them like it says in the float SB. The carb float armature can only be set if the carb is off the engine and turned upside down.
