Yeah, the only twin saw that I know about was the Echo 62cc twin. They are very rare and hard to find. I scored one finally. I have a BME crankcase for it. It will make a nice, compact 62cc twin using the internals of the saw engine and the crankcase from BME. I think it could be made into an 80cc engine if I could just scare up two sets of 40cc cylinders and pistons, but no luck on that score yet. Buying them from the parts suppliers is a joke.... WAY too expensive.
