Default OS FS-90 rear rocker

Does this engine have a crankcase vent?

Yes, the crankcase vent was on the rear cover/cam housing.

Is a o-ring and gasket set still available for it?

No parts specific to that engine are available. It has been out of production for a very long time.

Would the O-rings for the 91 work? Really need one for the pipe from the carb.

We don't know. There is no parts cross-reference, and we don't know the size of the o-ring for the intake manifold to carburetor connection.
