Y'know, if like me you're really brave, (or bloody stupid!!), you could try the following:- remove plugs so engine is easy to turn over, insert cigarette paper in between points, pull on paper until it feels like it's about to tear, then VERY slowly turn engine over whilst watching timing marks until you feel a slight release of grip on the paper which signifies the moment the points are just starting to open, and that's the point at which to set the 'F' mark. Not very scientific I know, but I've got away with using this method from 1967 on Hondas ranging from 90cc to 750cc, and I've got away with it so far!
