Richard:
Have you "rounded up the usual suspects"?
Check the plug gaps?
Verified that the #2 plug is the same type as the others, and
verified the heat range of the plugs?
The compression check says that the rings are OK.
If your emissions stuff is connected, are you getting oil into
the intake manifold through the emissions connections? Pull the hoses
and look for oil in them - oil in the top end can go through the
breather and into the carbs.
Other stuff to check:
Are your valves operating correctly on #2? If you lost a lobe on
your camshaft you could see issues. Interestingly, it was my #2 cylinder
that had a flat lobe (exhaust valve).
Are you running a supplemental oiler? Try removing it and see if
that changes anything.

I'm trying to diagnose an issue I'm having with my TR6. I took the TR
on a
fairly lengthy trip recently and was having problems with #2 fouling
out.
I've always had issues with #2 and thought that a recent rebuild of the
cylinder head might rectify the situation. I was wrong.
So with this in mind I did a compression test last night and came up
with
the following figures - dry. Btw, the head was shaved to achieve a 9:1
compression ratio.
#1 - 180
#2 - 180
#3 - 150
#4 - 155
#5 - 165
#6 - 180
Obviously #2 doesn't have a compression issue. Aside from the variance
in
the cylinders, I suppose I'm looking at a bad ring or broken ring to
keep
coming up with oily #2. Am I missing something else? I didn't check
the
discumbobulator and the hyperspace module is in good working order.
Ideas?
