Title: gasket thickness
Post by: philip metzner on February 25, 2010, 04:08:22 PM

does anyone know how thick the gasket between the cylinder and crankcase on a wen-mac mkII should be?

I have a Wen-mac "Mk XII", a McCoy "NO. 2", and a no-name oddball with a Wen-mac cylinder and a cylindrical crankcase -- none of them have any discernible gasket between case and cylinder.

(I should see if I can get any of these running.  Hmm...)

HTH.

The old style Wen-Macs with plugs (MK I through Mark V) had black tar paper like gaskets between the cylinder and case and between the the head and the cylinder. Disassembly of either frequently destroys the gasket, so if you can clean a gunky engine w/o  breaking those seals, maybe better to let sleeping dogs lay. Also it seems that some (maybe all ???) of the glow plug Wen-Macs came equipped with a second aluminum glow plug washer that went between (or in lieu of) the standard copper glow plug washer and the head. All Wen-Macs have the same paper rear case cover gasket.  I detest fabricating gaskets by hand and wish there were a better way.  Guy Eaves or Bill Netzenbaum could probably be of more help on this though.

As a youngster, I vaguely remember using old playing cards for gasket material.  In fact I use them for gasket material on the so called muffler to engine seal.   :)!

A Manila folder is good material to use for gaskets.
