Thanks for the suggestion, Vivo. That brings me to the other problem I face...Communication barrier!! I will have a scout around (with parts in hand) and see where my limited Japanese gets me. I think also, the next warm, sunny day I will get out there and snap a photo of the old girl, upload it and see if anyone recognizes her.
I think I read somewhere that 2-strokes are getting harder to get in the US. We are facing the same challenges here in Japan. They aren't making nor importing these engines anymore..Shame!! Always been on a 2-stroke. Nice and easy..
