A cylinder for an internal combustion engine of a manually guided implement, and a method of producing such a cylinder, are provided. A cast cylinder body that peripherally delineates a cylinder chamber has formed therein at least one transfer channel that is open inwardly into the cylinder chamber and includes a central portion, extending approximately parallel to the cylinder axis, and a head portion that above the central portion faces in the direction of the cylinder chamber. A cylindrical sleeve covers the central portion of the transfer channel inwardly in the direction of the chamber. The sleeve extends in the direction of the cylinder axis beyond the central portion and ends below the head portion.
