How do I get the piston sleeve out if it's stuck?

Put it in the freezer for an hour or so. When you take it out, the block will start to warm up and expand first, usually enough to make it easy to tap out the sleeve.

The old trick is to put the piston @ BTDC position, then insert a zip tie into one of the exposed piston sleeve ports. As you turn the crankshaft, the upward motion of the piston pushing against the zip tie will push the sleeve upward.

I didn't know about the freezer trick, that's interesting.

Aluminum responds faster to temperature change. If you cool the engine you shrink the brass and the aluminum, then when you heat the engine to room temperature, the aluminum should expand faster than the brass, making it easier to remove. Also the brass being on the inside plays a small part in it warming up last.

I doubt you would have great success trying with a freshly cold engine.

If you don't have a zip tie, you can use some folded up card board.
