Well the piston needs to be at the top of the stroke before you take the backplate off,or you will break the piston skirt off. To get the rod off the crank,you need to lift the sleeve out of the case by pushing up on the bottom with a toothbrush handle or piece of wood(something that won't scratch) the piston and rod will stay in block.with the piston up towards the top the rod should slide right off the crank. then the crank should slide out the back of the block(may be tight in the bearings) Pay attention to the way the piston and rod are put together,if you're gonna take them apart.

Did you break it off when taking the back plate off? if so you probably don't need a sleeve,but it would probably be best to get both piston and sleeve.how much fuel through engine?
