I went to pull the prop through prior to starting yesterday and it turned through three blades and stopped solid. What the ? Went home and researched on the web and learned about hydraulic lock on 912s. I went back to the airport and pulled the plugs and sure enough I got a shot of oil out of one cylinder. buttoned everything up and the engine ran fine. It had been sitting for a couple of weeks without running. Can I expect this to be a normal occurance or is there anything I can do to lessen the chances of this happening. My understanding is it has something to do with the oil tank being positioned higher than the crankshaft. I know I had an Europa for several years with a 912 and it never had this issues even after sitting idle for a prolonged period. It's oil tank was mounted much lower
