Hi Scott, Interesting that these saws made it to Italy.
I have the John Deere version with the broken handle bracket and rear handle just as you said.

Runs great. I had it at work and we had a young German engineer visiting so I let him cut with it and he was amazed at how smooth a saw older than him could cut.
I had a gent in a training seminar from Washington state who told me they made a backpack air compressor from this engine, with one cylinder making the air, and it was used for operating pneumatic loppers for pruning in orchards. He has a customer still using one regularly. He sent me an IPL but I can't find it, but I did get this pic from a friend who works at Echo in Lake Zurich:

My friend at Echo showed me a video of his snow bike, which uses this motor to drive a small track on what is a light bike looking frame with a ski to steer the front. Pretty cool.
I had heard but don't know if it is true that Echo had plans to make 3 saws, 60, 80, and 100 cc displacement but since the 60 cc version I guess didn't take off as hoped the bigger models never were developed.
