ABSTRACT:
A slow speed adjustment mechanism is provided that allows an internal combustion engine to be manually adjusted to operate at a slow speed which is slightly faster than the idle speed of the engine. A tubular member is provided with an outer threaded surface and an inner threaded aperture and is rigidly attached to a support plate mounted on the engine. An adjustment head is provided with threads that mate with the threads of the inner threaded aperture of the tubular member. Rotation of the adjustment head moves it axially relatively to an axial end of the tubular member. A flexible shaft can be attached to the adjustment head to allow manual rotation of the adjustment head, whereby the idle speed of the engine can be modified for purposes of trolling or other uses which require a slow operation of the engine at a speed which is slightly greater than its idle speed.
