I think I learned a lesson and paid $40 to do so, plus what I have in bearings and fancy glue. I won't be buying old saws without checking them out carefully. You can't do that on EBAY. It seems pretty dangerious to buy such items sight unseen. There is not much left to send back anyway. I am dissappointed at not getting a 65cc engine out of it and spending so much time. It would have been a very nice job. I'm getting pretty good at prop hubs and paring down crankcases.
I did send the guy a scaving E-mail. His rating is 99.9%. My wife sells on Ebay. She tells me I can't give him a bad rating without giving him a chance to make good. Maybe he will do so? He did answer a question on the item and described it as,
" the saw is actually in pretty good shape- I'm not sure why it was retired- but there is still plenty of good usable parts on the unit"
He has a real company, I guess I can hope..
Next day,
He did good! My money was refunded. I guess my synicisim was unfounded. Conistering his attitude and quick action I put him on the "good guys" list.
Maybe I am a gluttion for punishment? I found another crankcase and crank on EBAY. I bought it today. This seller guarentees it to be good. I figure I have made all the conversion parts so I might as well finish the project.
