Because 2 strokes open the both the intake and exhaust ports as they approach BDC, you have to accept only the peak compression reading. Leakdown tests are difficult, to say the least.
Do one test “dry”, then squirt some light (sae20) oil into the plug hole and test again. A significant difference is obvious and telling.
HTH.
Makes sense. That implies wear around the rings/sleeve are the primary concern?
