If you can't get the timing to work because the coil plate is turned as much as it can to advance but isn't enough, I think you can remove washers from one side of the points and fit to the other side, move the points closer to the cam that will give a bigger gap then close the gap with the washers, where the green arrow is put more washers ,I've never needed to do this but looks like it should work.
Yes wasn't a lot wrong with my Pope mower Speedy ,number 4 pic is the starter square drive.
