The starter on my horizontal shaft mid sixties mower has started to chatter while the mower is running. I've seen that kind of business on outboard engines when I was a kid.
I took the cover and rotating screen off, and five or so ball bearings dropped out. I didn't look under a magnifying glass, but it basically looked new, and w/o lubricant inside.
I'm guessing all it needs is some light, perhaps, lithium grease on the balls to hold them in place whilst I reassemble it?
