CARBURETOR WITH ONE PIECE CHOKE VALVE AND SHAFT ASSEMBLY

摘要

A carburetor including a one piece choke valve and shaft assembly including a shaft, a detent plate formed on a first end, a lever arm formed on a second end, a pair of opposing collars formed adjacent the detent plate and lever arm, a valve plate centrally positioned on the shaft, and opposing splines formed on the shaft enabling it to be inserted through an assembly slot cut into a shaft bore in the carburetor body. The detent plate includes a partial annular slot encompassing the angular range of travel of the choke valve. First, second and third detent pockets are formed along an outer edge of the slot. A positive positioning pin engages or interacts with the detent plate to positively position the choke valve in first, second or third angular positions corresponding to “close choke”, “half choke” and “open choke.”
