Here is the top of the carbon. It was quite dry.http://i77.photobucket.com/albums/j66/c … 6c7jrk.jpg
But top of motor is oily wet.

At 3 o ‘clock you can just see the drain channel in the seal area. http://i77.photobucket.com/albums/j66/c … 1442267976
Put wd40 in seal area and it drained right down to the reed plate area, can barely see a drop on the screwhead so the drain is not blocked.http://i77.photobucket.com/albums/j66/c … 2354582278
The carbon itself is smooth and near dry. It was step face down with a square ring that was installed last winter. No sign of any leakage past that ring.http://i77.photobucket.com/albums/j66/c … 6w5jvi.jpg
The bottom of the magneto plate is oily with oil into the magneto bearing .http://i77.photobucket.com/albums/j66/c … l1e0fl.jpg
Can this be leaking through the crankcase joint – although by spinning the crankshaft with just a wrench I could not see a leak? I would appreciate any opinions How difficult is splitting the crankcase and resealing?
