Abstract: A system, comprising a plug-in data structure to store plug-in data, the plug-in data structure including an initial list and an end list and a plug-in manager to read the plug-in data structure and start plug-ins corresponding to an order in the plug-in data structure, wherein the plug-in manager starts plug-ins on the initial list prior to plug-ins on the end list.

Abstract: A throttle cable linkage for a throttle valve comprises a throttle cam having a shaft opening enabling placement of the throttle cam on a throttle shaft of the throttle valve. The throttle cam includes a cable socket having a socket axis, an open socket inlet and a socket base. The throttle cam has a pilot trough and a ramp trough. The ramp trough has an interior ramp slot which extends along the length of the ramp trough and into the socket base. A throttle cable assembly includes a throttle cable and a cable knob. The throttle cable is sufficiently stiff so that control of a portion of it away from the cable knob can enable piloting of the cable knob through the pilot and ramp troughs causing the cable knob to fall toward the socket axis with the throttle cable falling through the ramp slot into the cable socket so that the cable knob is adjacent to the socket inlet.
