Gasket Materal
Since parts for older engines become harder and harder to find does anybody know either the thickness for GASKET material on lets say an OS .61 Hanno or YS .61 Long or short stroke or what type of material can be used to replace the original gasket.

Lots of modern engines don't use gaskets for backplates and the like. YS did use paper gaskets for the regulator housing; thicker than typing/copy paper, more like manila folder paper.
On the rare times that I need to have a gasket for a back plate, or such, I make it from a sheet of typing or copy paper; could use a piece of "heavy duty" aluminum foil.

As far as the answer to the orginal question, I went and got out a 61SF-RF gasket kit and with my calipers measured the the back cover gasket at about 0.25mm. I next measured some used gaskets and it appears they squish down to 0.15mm.
I also use the vanilla envelopes, playing cards, cereal box cardboard.
What ever i use i always make sure to coat the gasket with some type of oil to make the engine easy to disassemble if needed.

RE: Gasket Materal
Loctite makes a gasket eliminator 515 sealant, part #51517. Fills gaps to .010 inches. Cures in 1 to 8 hours. I've used in in place of paper gaskets that are no longer available. It's also a strong adheasive, so don't go overboard with the application. I had a back plate that was almost impossibe to remove because of the excess sealant that got between the backplate and crankcase.
