Fairbanks-Morse Magneto help

It has points, all older gas engines had points, ive never came across one that didnt until they eliminated points and went with breaker less ignition
The problem with old stuff like this generator is sometimes its expensive to fix just to find if the generator is putting out.....Ive been there numerous times and its a gamble and maybe better to put it to the side until a cheap or free used mag can be sourced
My mag and I understand most have a spring loaded impulse devise that spins the mag fast as you turn over engine and in that one second it creates a strong spark....
My 4 cylinder has a hand crank and most likely could never crank it over by hand fast enough to start but the impulse device in the mag solves that problem
It could really it could be a lot of issues with the mag why there is no or weak spark
