It could also be a styrofoam coffee cup in the gas tank (I tore down a few 
motors after that trick. Only cure was to fix the engine, change the fuel 
tank AND the lines to ensure it didn't recur. That and put the filler where 
%$#@&* punkass kids couldn't mess with it!

Well I got back in time today to pick up the head from the
machine shop
(#4 intake stuck AGAIN! 20 miles after a valve job). It was
again
VARNISH or gunk on the stems. The combustion chambers did not
look very
clean when I pulled it, and it was *spotless* when I put it on.
I had
soaked the cylinders in Marvel Mystery Oil over the last few
weeks, and
originally attributed it to that. (I cranked the motor over for
about 10
seconds with the plugs out before I fired it up though.)

Well Jim Blair said he 'hadn't seen anything like those valves
except
sugar in the tank', and at this point, I suspect something like
that may
be the case.

It ain't oil -- there was plenty of oil to the top (I even took
a video
of it). I'd changed it TWICE in 40 miles (not unreasonable since
it sat
for so long) the first time with Sea Foam. The oil is clean and
yellow
and transparent.

It ran exactly at thermostat temerature for it's one hour of
operation.
I measure it with an IR thermometer (because the dash gauge ran
about
2/3rds to the H mark so I got curious).

There was an oily residue in the bottom of the intake after only
an hour
of driving. That's odd. New-old-stock carb.

So tonight I just drained the carb into a pyrex beaker, and it's
way too
dark orange, and slightly cloudy. I will evaporate the 100mL or
so and
see what's left behind. I assume that no more than maybe a
microscopic
film shold be left in the beaker.

(When Joe dropped the car off here, the tank was empty, so there
was no
need to dispose of old gas. I put a fresh two gallons in and
drove it to
a gas station and filled up.)

Tomorrow I'll siphon a bit from my Hornet and compare colors. I
think at
this point I need to examine what's in the tank.

Needless to say I'm a bit paranoid at this point. Nothing like
this has
happened to me before. Oh well, that's old unknown cars for you!

These pictures here are from BEFORE the valve job, and I didn't
see them
out and dirty this last time, but they were apparently really
varniushed
