Abstract
A crankshaft () for a crankcase scavenged two stroke piston engine () is disclosed. The crankshaft () is configured to rotate around a rotation axis (ax) during operation. The crankshaft () comprises a crankpin () configured to move in a crank plane (cp) during operation, and a first and a second counterweight () arranged on either side (S, S) of the crank plane (cp). The first counterweight () has a first outer radius (r) measured from the rotation axis (ax) and the second counterweight () has a second outer radius (r) measured from the rotation axis (ax). The first outer radius (r) is smaller than the second outer radius (r). The present disclosure further relates to a power unit (), a crankcase scavenged two stroke piston engine (), and a hand-held power tool ().
