OK, I received my carb gasket sets from Australia, included 2 rubber gaskets, 3 O-rings per carb. There is a small O-ring, medium O-ring, and large O-ring. The 2 gaskets are the float bowels and diaphragm covers, small O-ring is for the pilot screw, one of the other O-rings is for the needle holder I believe(medium or large?), and I can't recall what the other O-ring is for (medium or large?). I am at work so I am away from the bike and Haynes manual. Anyone? Thanks!

As far as I can see looking at the fiche - You have 3 o rings - 1 for the needle holder, one for the pilot screw and one for the drain screw.

Hope this helps matey!
:D

Thanks Mark, that's probably it. The medium O-ring is for the drain screw and the large O-ring is for the needle holder. Cheers!

Rock and roll..no worries Jeff.

Glad to see you are still fiddling with it... We need some footage of you razzing it up and down the street...at least til you get to a track
