Sounds like old fuel/oil residue that built up in the lower leg over the years is leaking out. Might be running too rich?

Running at idle on the cuffs it will tend to load up and get a bunch of unburned oil and fuel in the exhaust. The exhaust normally goes out through the prop hub, so that's where it'll pile up a bit. If it seems to run normally, don't worry about it.
