Removed remaining baffles. Removed nuts holding cylinder #4 amd pulled cylinder out. Surprisingly, the crankcase rotated! But the piston is still stuck in the cylinder. All the other three cylinders are apparently free. Re-secured #4. Removed cylinders 1 and 3 w/o difficulty. Pistons, rings, and cylinder walls look good. Stopped at FBO and borrowed cylinder wrench and spark plug air fitting.
