Hand-held power tool

A hand-held power tool has a two-stroke engine with a cylinder with combustion chamber and a piston disposed therein that drives a crankshaft supported in a crankcase. In at least one piston position, crankcase and combustion chamber are connected by a transfer passage. An air passage supplies in at least one piston position combustion air to the transfer passage. A mixture passage for fuel/air mixture is provided. Air and mixture passages in operation are at least partially connected to each other. Part of the mixture passage is formed in a carburetor where a fuel port opens into the mixture passage. The mixture passage opens into the crankcase with a piston-controlled mixture inlet having a width in circumferential direction of the cylinder. Upon upward piston stroke the mixture inlet is connected to the crankcase with a portion of the width before a connection of air passage and transfer passage is established.
