Understanding 2 Stroke Engines vs 4 Strokes. My 2 Stroke Johnson (Outboard) Part 4

My Johnson is under performing(!!) and I'm feeling the pressure (or lack thereof). Should I tear it apart? Engines are complex and there is a lot of variability between them, so how to check compression may be different depending on the engine. I got through the details of 2 and 4 stroke engines, show the differences that will affect compression, and do some experiments to confirm.
