Starter rings:
I have an old 08S, that my father bought in 1965. As far as I know the starter ring ( cup that bolts to the flywheel) has never been changed. It looks to have some sort of nylon insert inside the cup I mentioned. It's getting worn down a bit, but the saw never refuses to start. I'd say, buy an original repacement and try it. This saw always starts on the first or second pull as long as there is gas in the carb and has a clean plug. It's old but reliable. If your cranking and pulling on the saw a lot to start it, I'd say that you have other problems to check out. JMO. Lewis.
