Yamaha 50hp Carb Orings too small on Silencer facing side

[jcr6502]

The parts listing references part 17 which is O ring 93210-35M-86-00 for the Silencer facing side of the carb. I have noticed the ID of this to be a few mm smaller than the OD of the carb machining it sits on. Stretching the ring to make it fit, albeit temporarily makes it too thin for the detents to hold it in place. Is this a typo in the catalogue? Is there another part number for this O ring?

F50TLRB

I looked at all of the carburetted F50's and the same gasket is shown for all of them. Don't think it is a part number error.

Ive checked multiple sources too and agree the part number is correct, but the calipers tell a different story. Ill go through my media and find something from assembly.
