ABSTRACT:
An apparatus for use as a governor arm/governor shaft joint in a governor system (10) and a method for zeroing out the tolerances in a governor system (10) used in reciprocating internal combustion engines. The apparatus is comprised of a governor shaft (12) with first and second ends having a tapered portion (21) located near said first end; a governor arm (13) with first and second ends having a tapered aperture (29) generally located near said first end that is arranged and configured to match the tapered portion (21) of the governor shaft (12); and a securing element (31) that forces the tapered portion (21) into engagement with the tapered aperture (29). The tolerances in the governor system (10) are zeroed by rotating the governor shaft (12) to its maximum position; loosely placing the tapered aperture (29) of the governor arm (13) on the governor shaft (12), attaching a linkage (14) between the governor arm first aperture (24) and the carburetor valve ( 15), attaching a governor spring (16) between a control plate (17) and a second governor arm aperture (26) whereby said governor spring (16) is arranged and configured to rotate the governor arm (13) until the carburetor valve (15) is in its maximum open position, and applying a securing element (31) that forces the tapered portion (21) into engagement with the tapered aperture (29).
