I have a 28" RER of 1980's or early 90's vintage. It would go about one or two turns around the yard and quit moving. I figured the rubber-edged drive disk was worn, so I bought a replacement, and also got the paper-type clutch disk. I took the part with me. Neither me nor the shop guy noticed the difference in the rubber disk. The new one didn't have a brake lining. I put the old one back on with the new friction clutch disk and it worked fine like that. Question is, can I still use the different rubber disk or will it not be a good fit? This is my late Dad's old Snapper he gave me a few months before he passed away. Just wondering if I need to return it or can it still be used. Don't have any hills to mow so not worried about sudden stops...
