OS PARTS

Won a bunch of OS parts off of Ebay for not much mpney recently - I though they were venturi inserts and so they proved to be.

One of the large one fits my OS Max III 35 - they other two don't (sit too high) - are they for a different motor or do the just need a bit of work?

Any idea what engine the smaller ones are for?

Also any idea what the black plastic tubes are for - just look like spacers to me?

I THINK the smaller inserts are for a .15 (either the MAX-I or MAX-II, but not MAX-III).
The black things appear to be spacers shipped on the crankshaft between the thrust washer and the prop washer. I don't remember having these on an OS engine though.
