Eazy-off oven cleaner used to work like magic. It was the last resort
before a teardown. They have dummed it down now because it used to take off your
skin. But it might work. You can cycle the apex seals through the leading
(Lower) plug holes. Use a wooden dowel. It is a caustic so it will damage
aluminum. If the engine starts, then no foul.
If not you were going to take it apart anyway. Wear eye protection.

Agree on
50/50 ATF / Acitone, Dave Atkins says it's carbon build up, so next try a soak
with a carbon remover.
