Ah. The pulley look a like is the little saucepan lid like plated pressed steel cover that is held on to the dynostart by a clip. it is make-able/botch-able, till a real one comes along. It has a seal.
Triple points in two flavors or you put on a, hmmnyah, Suzuki triple set, that can be electronic? One of the Japanese manufacturers did one that goes in the space available. Points can be hard to get for one size of original points, I forget which. Possibly the smaller cam was an attempt to use standard points but was inaccurate for some reason - probably error increase from a fractal increase on a smaller cam. If so then the larger cam had smaller points that are not so easy to find. These facts may be mixed up and a different outcome achieved, but its a start.
