As you know, there is not a lot of room to get any sharp tools down into the wells to cut up or scrape out the rubber.
Thanks for any help you can think of.

You can remove the plug tubes. Remove the head cover and then remove the tubes by using two tube nuts tightened together to grip each tube. Another method is using a cushioned pipe wrench, placed as close to the head on the tube as you can, to loosen them. They have adhesive (Part No. 08833–00070, THREE BOND 1324 or equivalent) on the threads, so they will be tough to break loose. Clean the threads carefully before applying the adhesive and reinstalling the tubes. The tightening torque for the plug tubes is 29 ft-lbs, using a tube nut to tighten them.
Be careful getting the crap off the plugs. Use a vacuum or compressed air to get all the crap out of the plug wells before you remove the plugs. Anything in the plug wells will end up in the cylinder when you remove the plug. Don't let anything drop into the cylinder when the plugs are removed.

I have had to do that before, A small wood chisel worked for me then pick the larger pieces out with tweesers and blow the small bits out with air

Thanks to both of you. I'll try to chisel/chip the rubber away first. It's good to know that if that doesn't work I can still remove and replace the plug tubes as a last (and more expensive) resort.

You don't have to replace the tubes, only remove and reinstall them. It only costs time and some gasket adhesive.

FYI, I was able to get the four spark plug tubes removed and the melted plug wires chipped away, vacuumed, and blown out. I replaced everything and it started up fine. Thanks for your help.
I now have a cooling problem (surprise, surprise). I'll post that problem in a few minutes so please take a look at it. Thanks again.
