Take your muffler to a good hardware store, and start trying screws. From your description, it could be 5-40, 3.5mm, or 3mm.

Any one got one ? and know what thread the screws are ?
It's probably a metric thread. 3 or 3.5. The problem could be that they went with a non standard pitch, but that is unlikely. They were OS clones.

Here is the manual for the OS FS-91S II Fuel Injection engine which I found very hard to find due to the engine now being discontinued, though parts can still be purchased for this engine.

I just scanned a Rossi manual. it has parts listings for .21-.90 engines. There is no date, but it should be early to mid 90's.

I also had a manual for a Rossi .90 RV RC marine engine.
