Status: offline 		Having a tough time making and ID on these parts..

I know they are for the FS-90 (pre / non-surpass) engine, and I have looked
at the exploded view of the engine, but I can't seem to locate
these parts...does anybody recognize them ?

They are threaded socket worm type screws...

Thank you!

Status: offline 		The pictures show parts bags that have been re-stapled at some time. We have an old exploded engine diagram. Screws such as the ones in your pictures just are not used in the old FS-90. We cannot even find that part number in the FS-90 engine diagram.

We'd have to guess that those set screws were not original to those packages, but put there by someone previous to you for safekeeping. We cannot locate that part number.

My best guess is that these are for prop retainer.

Status: offline 		Actually, the package pictured in the background (darker blue header card) has never been opened, the staple
marks are factory, so this leads me to believe that the screws were used somewhere on the
engine, or the factory mispackaged them...

Still a mystery to me!
