I stopped flying my 912ul at the end of May. Had to leave town to work. Came home in Oct and hand pitched the engine and all was fine. Did not start in Oct. Got home to stay lately. Went to roll over the eng by hand and no go. I pulled the plugs and crankcase oil came out of the two back cylinders. Can anyone tell me what I am up against? The engine has less than 200 total time.
