To directly answer the clutch chatter and adjustment question.

YES, the clutch must be adjusted (for most of us that means installed in the
car).

I adjusted the clutch in the car.

1. Pull the transmission (seems obvious)
2. Bend the retaining tabs down away from the three adjustment nuts.
3. Loosen the nuts until you can turn them by hand.
4. retighten them by hand, then snug them down with a socket, about a quarter
turn each, until the three fingers stop rising at the end. ( I know this not
very technical) It will not take a lot of torque to get to this point.
5. I used a caliper to measure from the outside edge of the center ring, down to
the pressure plate cover. (directly below the edge of the ring) Measure at
least three different spots around the edge of the ring.
6. Slowly tighten or loosen the nuts until you get the same height measurement
all the way around the ring. (it will never be truly the same all the way
around, but it should be within a couple thousands)
7. BEND THE TABS back up to hold the nuts. Forget that and you'll be doing this
again later.

It took me about 20 minutes to do this.

I'm sure the guys with the cool tools and experience are gasping and wondering
what kind of idiot would give advice like this. Well that would be me, but my
clutch doesn't chatter any more.

I hope this clears the picture a little, or at least gives you a place to start.

Scott's explination sums up the biggest cause of clutch judder and how to fix
it, but don't forget the other possible causes, oil on the plate, weak
transmission mounts, and forgetting to put the bronze bush in the back of the
crank !

I did have one Amphicar which allowed adjustment of those three bolts on the
pressure plate while the engine was still in the car... someone had cut a hole
in the top of the alloy transmission about 2 x 1 inch that would allow you to
look inside and see the clutch working, very not recommended !

I have a picture of the clutch from the Triumph manual with some notes on it
