Mark, thanks but no thanks!! I used to rebuild for other people but if I would have gotten one like this it would have been the last one done for a friend.
This engine was given to me a couple of years ago as a gift. Just a great running engine and fits my old Kaos perfectly.
I also looked at the price listed in tower for a new one, $300 magic beans so I wasn't going to let it beat me. No one even mentioned anything about me forgetting to install the lifters!!

For any of the new guys I posted up a photo of a home made air cleaner on this engine. Sorry wife but you can live without wearing two nylons!!

It's just the thick end of nylon hose over the carb held on with a very tight O-ring. I fly off of a dry lake bed and this helps keep the grit out.
Anything that helps keep me from rebuilding it again is OK with me!!
Price of the rebuild was about $13.00 but I just happened to have a new ring in my supply box. So for about $25.00 I have a new engine and saved myself about $275.00. Worth the effort!!
