I have never seen the stuff jam the valves but what you are describing
sounds like a vehicle that had been sitting for a very very long time and
had developed a shellac like material in the fuel system.  I have seen it
completely fill up injectors and clog up fuel lines worse than any
cholesterol problems.

This is one reason when I get a vehicle that I know has been sitting for a
couple years I will pour about 5 gallons into the tank and let it sit for a
day or two and then using just the pump, run it out into a container again
to inspect.  I also remove the fuel line from the pump to the engine to
check it out (if metal) and just replace it if rubber.  Some things an "old
guy" taught me when I was a kid. (of course werent too many electric pumps
around in those days but same principals.)

Planned insanity is best.
Remember that sanity is optional.
