hi toyman-just picked up the same unit looking to strip and re-build this engine managed to buy set of points and new piston rings (if required) have never worked on this unit before but should be straight forward.I strip and rebuild 2/4hp.outboards Started  as a hobby now takes up all my spare time but I enjoy it.Keep in touch if you happen to start before me I have a 4hp mercury coming to a finish and a 40hp mercury where the electrical work needs sorting out so will start the rebuild on the Anzani in the new year --2strokepwr
