Thanks to everyne for your responses to my question.
We now know why most Macs don't have full-circle cranks - I for one had not realised that expansion chambers reduced their value. My retired karting buddy seems to be all enthused, and wants to see my Macs next time he is down here - perhaps he will want to get them running? :-)
