I use a piece of 1/8" brass tubing that I flatter about a 1/4" on one end & bend 90 degrees . Put the crank back in with a prop on it . Hook the tubing hook part in one of the ports inside the sleeve , heat the engine with a heat gun or propane torch & turn the prop backward & that should lift the sleeve out. Use a heavy glove & don't burn yourself. Works for me ! Give it a try. MAX H.
