Shouldn't be a problem getting a starter cup to work Norm ,I think the later model starters are a better working starter but I do like the original look of the earlier starters,.I once bought a burnt out $15. Victa 18 mower with melted base and carby because the cowl and recoil starter were still good.
Yes that pawl holder still looks usable Blue and QSR has shown what they look like when worn out and the pawl can drop out.
This is the first time I've tried these eBay pawls and QSR is right they are a little loose fitting compared with the original solid ones that is in his second pic.
The eBay one is flat metal that is rolled for the round pivot ,I was thinking of hitting a small screw driver into the round part to expand it a little for a better fit.
