The absolutely standard way to do this is to use the buckle end of a cable tie and put it in the exhaust port from the cylinder side not the exhaust stack side.

Then turn the engine over and it will jack the liner out.

I was shown this by Aleesandro Rossetti who was the development engineer at the famous OPS factory in Italy.

If the engine is ABC and savagely over heated the liner bells out at the top and they are very difficult to get out, this usually only happens in competition engines though.

I'm sure this was a method recommended by the late Brian Winch in several of his articles.

there was a slight part of the liner visible through the exhaust port, i pushed on that with a flat bladed screwdriver and it lifted just enough to get a knife under the top of the sleeve and ease it out
