[tech]: help! moving timing

[ralexander03@snet.net (Rick Alexander)]

I've had two of these cranks with snapped off keys. I got them that way so
do not know what the symptoms are but I can imaging that this is what it
should be like.

I was wondering myself if a good machinist could cut a keyway into the crank
so that a normal key could be used. Any thoughts on this from the experts?
