| Andrew, I own four Knight 50s. One plastic sport, two all metal pro versions and now a 3D. They have all come from the factory with the o-ring of which I have mentioned, with the exception of the newest.
I looked at the manual for the other versions and this part also does not show for the Sport version. The manual for the pro version shows part #99-0501 (the o-ring) between the washer that seats against the step of the older type step shaft and the bearing in the clutch bell.
Compass has since done away with the 5mm to 6mm stepped start shaft design, and now uses the e-ring where the step used to be. I don't know why the manual doesn't show the 0-ring in these later versions, but I can assure you that it has been there in both of the aforementioned models or I would not have said that to be the case.
I can realize that with the perfect, flawless nature of the Knight manuals, that it's highly improbable that a mistake or omission would occur. I'm telling you what I know about the situation, take it or leave it. If you think that the start shaft is supposed to have 1 to 1.5 mm vertical clearance to flop around you are certainly welcome to build it however you wish.
I bought the replacement o-rings from MTA on their Knight parts list. Sorry bud yourself.
