It's not melting, the substance they used to pot (encapsulate) the electronics tends to do that after a number of years.

Clean out as much as you can of the old potting compound, then fill it up with epoxy, let it cure, reinstall and it should be good for another 30+ years.

I doubt changing it will improve the running.
Do check the spark first thing is be sure both coils provide a good spark.
If OK then you can simply scrape the gooey junk out of the module and fill it with your favorite stuff.
Silicone,high temp epoxy or whatever.It's just age and heat that's made a mess.It is there to moisture seal the electronics inside it.
For the best running bike,the punch list is this.
Timing belts-replace them.
valve adjustments.by the book.
carbs cleaned up.the whole sha-bang.
a really good sync job.
