I actually watched most of this “test” the problem with all these YouTube test experts often is their methodology, where in the world did he get the idea to pour MMO into the carb when the engine was running? And what’s this about a “hot soak”
I know sea foam says you can dump it into running engine, but does MMO?
Does the fact that it doesn’t work
well when used in a manner that it’s not intended to mean anything?
If you want to see a miracle decarbonazation, dump water
into a running engine, the steam will clean astonishingly well, there is a huge amount of energy in steam.
Not that I’m saying do that, but it will clean out carbon, maybe I need or sell hydrogen dioxide as a engine cleaner? Put some food
coloring in it and there you go.
