This is so bizarre I felt compelled to join the forum after reading this post. Today, I was working on my 86' Beta TR33 trying to figure out why it had no spark. I popped the cover and voila, the exact same problem!!!! The key sheared off and the nut had backed out a bit. What I did was I used a valve shim that matched the thickness of the original key, then I cut off the side of that shim approximately the same size as the original key (I used a die grinder for that). Then it was just a bit of grinding to get the size and radius exactly right (I still had the original pieces that I could use as a reference). I put the flywheel back on, put a dab on locktight on the nut and she fired right back up! On a side note, does anyone out there have access to a rear fender for an 86' Beta TR 33??
