Knowing how "risky" it is to try to explain any of this to you, I make one brief try anyway. I am an "*******" -- I don't mind. EasyT, people on this forum are trying to HELP you -- including the people you are castigating. It is not surprising to me that there are people you find similar on the Harley forum.
I am seventy years old. Particularly over time, over the course of my life, I have gained a lot of respect for people who observe, and practice, and gain a significant amount of true understanding of any of variously many things, whether diesel engines, or the hydrodynamics of lifting foils, or the French Revolution, or the reason that self-driving automobiles have not fulfilled promises too often made.
True understanding is almost never "blunt" and literal. It is true because it "extends into" its subject in a way that "makes sense," flows with the profile and contours of the reality involved, takes the serious things seriously, takes the variable things with more variability.
So, take it easy, a little, for your own sake. People who have commented on this thread are basically telling you that one has to burn off (or maybe brush / maybe hold it up to a wire wheel / maybe scrub in some useful way) the carbon out of your screen. The saw ain't gonna work real good if it can't push out the exhaust. Simple, easy, true.
Our suggestion to you is that you just gently and simply align what you are doing with that fact. The other stuff, the BrakeKleen kinda included, is pretty much joist "noise" in your head. Turn down that noise. You will feel better.
