Abstract:
An engine speed control system, comprising:a throttle plate connected to a throttle shaft;a controller which is operatively connected to said throttle shaft to select an operating speed of said engine by rotating said throttle shaft in a first direction to decrease said engine speed and in a second direction to increase said engine speed;a first stop mechanism, for limiting the movement of said throttle shaft to a first position in said first direction, which selects a first idle speed of said engine; anda second stop mechanism, for limiting the movement of said throttle shaft to a second position in said first direction, which selects a second idle speed of said engine, said second stop mechanism being movable relative to said first stop mechanism, said second idle speed being faster than said first idle speed, said first stop mechanism comprises a generally tubular member having an outer threaded surface and an inner threaded aperture, said second stop mechanism being disposed in threaded association within said inner threaded aperture, an axial end of said first stop mechanism defining said first position in cooperation with an adjustment head of said second stop mechanism being threaded into said inner threaded aperture.
