Ah I see. I now hope mine has one as a couple of years ago it sheared all the little screws/bolts that hold the starter clutch to the flywheel through backfires and I replaced them with the highest tensile I could find! I must say when it backfires it doesn't sound like anything is slipping. I shall have to look closer next time its apart.
