Both engines were from Hummel engines (scot chasler) the first one had 92 mm with the stock stroke like yours. It was real good reliable engine for learning to fly the LE. Then the case cracked out the oil gallery.
I got a new case from Hummel and swapped out the guts. This one started running weird, losing power and making a lot of metal. so I strapped it down and ran it at full throttle, 30 minutes into the run engine stopped dead.
I sent it unopened to Hummel and Scott reported a broken crank in a place with the most meat. At that time I got Scott to to put 94 mm and full stroke crank assembly as used in the 45 hp models. I didn't have to much time on the engine when I shucked the prop in flight. The long stroke engines are hard on prop connections and you need to religiously check the prop bolts torq before you fly.
I have a new prop and only a few hours on it, hopefully it will stay together for a while.
