I find it interesting that some "old-school" mechanics would leave the carbon build-up as it improved the compression. Taking into account that I am by no means a learned person, this is the first time I've heard that a hot spot can occur due to the build up. The WD4O does a great job at removing most of the carbon, though.
My advice is: not to follow my advice.

Yeah, they do, and that is the case with excessive compression in mine(I bet even though I haven't pulled the head yet to see).
The problem is that it makes it an absolute PITA with the tuning of the engine, both carby wise & ignition timing wise, 'cos of the hot spots.
So, I don't think it is beneficial overall to have shyte loads of carbon buildup. A little bit, may be.
Particularly the thick layer of carbon build up on the piston crown is a real PITA with engine performance, and better have it scraped off.

Bloody expensive though. I used plain water instead.
I bet there is a backyard chemical alternative that we can add to water. (speculating stuff like detergent, vinegar, etc, )
Water definitely cleans the spark plug soot buildup & bit of piston crown soot buildup.
How about Seaform stuff?!!

I have the damn air tool, but can't locate the bristle discs.

you could spend 3 days cleaning or just spray it with the suby cleaner wait 10 min then wipe it off.
