Got a problem with the starter now as the drum is very worn so the pawl's are not gripping to turn the flywheel.......I have ordered a new one.
NormK came up with a solution to that as well by making vertical scribes inside the cup every 1cm or so to give the pawls something to grip.
Also there are washers in the starter shaft made of friction material a bit like brake shoe material that need to be placed in the right order with the other washers in order for the starter pawls to extend fully each time the cord is pulled.
