    Good thought about a plugged exhaust, the mud dobbers may have moved into the JW!
    I’m not sure I am understanding what you are describing, you seem to indicate that the rings are stuck, do I have this right? Can you compress the rings into their grooves with a small screwdriver? I hear ya, most engines have some slight scuffing/scoring here and there.
    If the rings are indeed stuck, you may want to center the pistons and fill the plug holes with engine tuner/seafoam with the cylinders in a vertical position.
    Does it look like the intake manifold has been off before? Any signs of powerhead disassembly, screws disturbed?
