I follow Buck’s suggestion and remove all the tar
when I’m changing the wires. If you don’t feel
comfortable removing the coil to avoid having to
re-aligning the shoes, you should be able to clean
things up leaving it in there
This picture is from an A-25. You probably missed
the springs and glass tubes. You have to be very
careful as they are easily lost it the clutter. You
likely never know they were there if weren’t told
to look for them.
Try some petroleum solvent like carb cleaner, kerosene,
engine de greaser, exct. to dissolve the tar and free
things up. Heat gun will also help.
When you get things cleaned up a little check to see if
the wires could be soldered on.
