Many thanks. I can not explain this, but...
I'd swear that like many of you my #1 plug was at 7 O'clock from the low
voltage wire this morning when I started all this. Rechecked the
compression stroke and it was 180 degrees off. I reset all my wires
starting #1 at 1 O'clock and it fired right up. There must be 1 or 2 valves
that are now too loose as there is too much clatter. It coughed out all the
crap from firing 180 off, I set the timing, balanced the carbs and went for
a ride.
It idles PERFECTLY smoothly. The problem I started all this because of,
declining idle as the engine warmed up, COMPLETELY GONE. Before, after a
ride on the freeway I could not keep the engine alive. Now its PERFECT!
And much more powerful. Very noticeable. The temp gauge used to sit about
half scale, its about 1/3 lower now.
I was really beginning to worry I had really screwed things up. There were
so many of the valves that were SO tight I was doubting whether I had been
doing it right. Now I know that I was and that some of the valves were set
WAY too tight. In fact, one of the lock nuts was stripped and the previous
adjuster had tightened it down over a thin strip of wire to lock it in
place. I replaced the nut. The screw portion of the rocker was ok.
Many MANY thanks to all who responded to my frantic pleas for help. Y'all
are the greatest!

Hmmm. Curiouser and curiouser, Jim. If the car had gotten a bit too hot,
and you had burned the head gasket between 3 and 4, I could understand
the car running as it did, especially if the valves were off just a bit.
But then, I would expect to see equal readings between 3 and 4.
I had hoped that perhaps you'd accidentally adjusted the valves
approaching max. lift instead of on the heels of the lobes, and that
would account for the outer four cylinders not firing properly. However,
if the valves weren't opening at all, or very slightly, I wouldn't
expect to see the compression readings as they are above. Compression in
those cylinders would be lower because neither of the valves was
opening, so there would be no fresh air to compress. And, of course, if
you'd accidentally gotten them too tight, there would be virtually no
compression.
My only suggestion at this point is the earlier one--pull the valve
cover and crank the engine with the coil disconnected--see if you can
see anything amiss in the valve train as it turns over. Maybe that way,
you might catch something which did not occur to you previously. Look
for erratic valve operation, etc.
I'm afraid I'm a little puzzled at this point, myself. (!) If the
ignition is okay and the timing is close, and the wires (and plugs) are
good, there's not much else except carburetion, and that doesn't sound
likely, from the symptoms.
Cheers, Jim.
