My engine finally locked up,kaput! It was progressively losing power and getting noisier right before she died.I got it apart this morning.The piston is chattered around the edge,bottom ring was broke in half but still in place.The needle bearing is intact at wrist pin.It appears the crank bearing is froze up tight.Cylinder looks to be salvageable,a little honing should fix that with a piston & rings it might come back.What is invloved in splitting the case to fix the crank-rod bearing?BTW I ordered a new engine yesterday so this will be a winter project rebuild. Thanks irefin
