MOPED ARMY

Remove the nuts at the base of the cylinder. Crack the bond between the cylinder and engine case to see if the crank still moves. If it does, turn the crank to push the piston(and cylinder) as far away from the engine case as possible. Wedge some wood blocks between the base of the cylinder and engine case, then beat the piston down and out of the cylinder. Once the piston starts to move, you make need to add more wood blocks between the cylinder base and engine case if needed.
