Once the sleeve is popped up slightly i like to spray a little wd-40 onto the sleeve and slowly and very very carefully pry it out with a screwdriver, be sure to work your way around the sleeve and remember to be careful, once you can get your fingers around the sleeve grab it with a shop towl and pull it out.
+1 for the zip tie.
Just to clarify I put the zip tie down from the top of the engine and put the Knuckle of the tie into the exhaust outlet then turn it over with the flywheel,
not in from the rear of the engine through the exhaust out let as I find it's easier to keep it where you want it so it doesn't slip in to far a get sliced off by the piston
