Single step starting system

A fuel enrichment assembly for a hand-held power tool comprising a housing, a power unit disposed within the housing and configured to operate at least in part in response to actuation of a trigger, wherein the power unit is an internal combustion engine, and a working assembly powered responsive to operation of the internal combustion engine, the fuel enrichment assembly comprising:

• a manually operated activation lever;
• and
• a lockout member integrated with the activation lever,
• wherein the activation lever selectively engages a first fuel enrichment mode associated with startup of the internal combustion engine in a first range of ambient temperatures and a second fuel enrichment mode associated with startup of the internal combustion engine in a second range of ambient temperatures based on a position of the activation lever,
• wherein the first and second fuel enrichment modes each correspond to respective different positions of a choke valve of a carburetor, and wherein selective engagement of the first fuel enrichment mode or the second fuel enrichment mode is enabled responsive to actuation of at least the lockout member and positioning of the activation lever,
• wherein the choke valve is positioned via rotation of a choke shaft, and wherein the choke shaft is operable in a direction opposite the direction of rotation of the activation lever in response to positioning of the activation lever, and
• wherein a geared coupler is provided to offset an axis of rotation of the choke shaft from an axis of rotation of the activation lever such that the activation lever substantially overlaps with an edge portion of the housing.
