Yup, that's it. FWIW, Moss sells a standard O-ring as an upgrade for the
cork ... I found the O-rings to last much longer in daily use than the
(replacement) corks did.

Based on my experience, I'd definitely suggest changing the float bowl
mounting seals as well. Probably a good idea to have a complete gasket set
on hand, in case one of the others is found to be damaged. And there's
certainly nothing wrong with changing all of the gaskets, since you'll have
most of them apart anyway.

I'm not sure I'd call it "easy", but I find it easier to do the job on the
car than to take the carbs off the car. You need to have a pretty good idea
of what you're doing, though, since it's hard to see.

Not a Grose jet then. The Grose jets have a big steel ball (like a bearing
ball) that is trapped inside the brass casting (so they can't be
disassembled to clear any trapped crud). The brass casting is quite a bit
larger, too, so it can trap the ball.
I've seen many other designs of needle valve sold as replacements. Probably
my favorite is the kind with the steel "needle", tipped with black rubber
(probably Viton or some such) where it meets the valve seat, and with a
small spring-loaded plunger where it touches the float lever. They seem to
last a long, long time ... I don't recall ever wearing one out. Sorry, no
idea where to buy them ... I've been running the same ones for over 15
years.
