Re: carbon build up

Looks like you're tying two or three unrelated events together.
If you're getting a (dead) miss, look in the ignition system.
I've posted here before, you can take an induction timing light and check the flash on each plug wire to see which one or ones are misfiring. You don't just have to use it on #1. Power from a 12 V source if 12V light. A complete ignition "tune up" maybe in order if your going to drive it much.

The carbon can come from several things, and improving the compression is moving right. The air/fuel (fuel/carb) system may need some more work, if it persists, as noted before. If the tail pipe interior looks constantly black, for instance.

Lifter noise comes from a few sources; wear, adjustment, oiling, sticking, etc. If one was bad, noise remains, you might have others that are bad, or a common source problem like lube system issues; pluggage, pressure(oil pump), etc. You can check the oil pressure via a test gauge and see if it's correct.

Troubleshoot each system independently rather than try to find the magic bullet.
The overall picture, how well you expect it to run based on it's mileage?, will determine how much time and effort you'll have to spend. There's a point where doing a lot more internal work on a worn gunked up engine, a rebuild becomes an option.
