Abstract: A hand held power tool is disclosed comprising an internal combustion engine, a workpiece driven by the engine, a boom extending between the engine and the workpiece, a clutch housing, a starter module, and an isolator. The clutch housing, the starter module and the isolator are disposed in a rearward section of the power tool housing the boom. The isolator is preferably formed of thermoplastic rubber, and is disposed between the clutch housing and the starter module. The clutch housing and the starter module are connected by fasteners extending therebetween, but the fasteners do not penetrate the isolator. Because the isolator is soft mounted, the isolator effectively dampens engine vibration forces to the operator and avoids local stresses which might otherwise lead to premature failure.
