I'm rebuilding my SU's on my TR3 and the gasket kit I got from Moss came with cork gaskets for above and below the spring that the jet goes through. #92 on this picture:

I see that they sell cork or rubber o-rings. I rebuilt them in 1990 and the kit came with the rubber ones so I used them... but when I took them apart the rubber was all falling apart.
I'm using the cork this time (because that is what I have handy) but I'm wondering if the reason for the rubber being all funky looking was because I put the cupped washer on the wrong way.
The question is... is the concave part supposed to point toward the spring or the cork / o-ring ???? The pictures don't show enough detail in any illustration I can find in the 4 different versions of shop manuals I have.
As I looked at it over and over again I convinced myself one way and then the other... the cup part seems to be a nice fit to the smaller diameter at the end of the spring and pushes the cork nice and flat. Or the cup part seems to form the cork nicely and then the flat side has nice even pressure coming from the spring.
How they came out is irrelevant since I'm the one who rebuilt it last time and I did it with the cup toward the O-ring but the cup seemed to cut out part of the rubber when it got compressed.
grrrrrrrr. /ubbthreads/images/graemlins/confused.gif
Anyone know for sure which way they should go?
And is anyone happy with the o-rings? I'm kind of leaning towards the cork at this point judging the condition of the rubber that I pulled out.
