I had one once,about 21-22cc.Light,2 rings,basiclly a copy of the echo.The only thing i didnt like was the flywheel was turned backwards so the fins where facing the block and the space that the hub would screw onto was only about 3/8ths to 1/2 inch around.[if i remember right].I didnt have a milling machine or even a drill press so i couldnt shave the lip out of the flywheel.I didnt have a lathe yet and was just starting into conversions so i sold it to a guy in CA.I think it would be dead on in comparison to an echo.Maybe a little lighter.
