A suspension mechanism (48) for mounting a combustion chamber fan motor (42) in a combustion powered hand tool including a flexible rubber web (66) secured between a motor retaining ring (50) and a cylinder head mounting bracket (60). The suspension mechanism is tuned for at least one of reducing the axial acceleration of the motor (42) and dampening the oscillation of the motor relative to the tool. The web (66) includes concentric grooves on its upper and lower surface and a number of bores (76) on the upper surface to provide the requisite flexibility depending on the characteristics of the tool.
