Abstract
A tool for removing a carburetor needle valve adjustment limiter cap has a handle with a set of jaws at one end for engaging the end cap and an actuator at the opposite end for applying force to the jaws to remove the end cap from the valve body. In a preferred form, the actuator has a slidable weight or mass that can be reciprocated along the handle to impact against a stop on the handle at an end opposite from the jaws. In another form, the actuator has a rod extending transversely through the handle and secured to it. In use, the rod is positioned against an abutment to provide a fulcrum about which the handle is pivoted to produce a force to pull the end cap from the valve body.
Claims8
A tool for removing a limiter cap from the stem of a needle valve of a carburetor comprising:
- a pair of jaws pivotally connected together and movable to open and closed positions, each jaw adjacent one end having a recess therein which forms in cooperation with an opposed recess in the other jaw a cavity for receiving a radially projecting arm portion of an end cap therein when the jaws are closed and having an inwardly projecting flange adjacent said one end which in cooperation with the flange of its opposed jaw provides a portion overlapping the arm portion of the cap when received in the recess with the jaws being closed, a handle operably connected with said jaws, a cam and follower for opening and closing said jaws in response to relative movement between said jaws and said handle, one of said cam or follower being carried by said jaws and the other of said cam or follower being carried by said handle, an actuator carried by said handle for applying force to the jaws for removing a cap received therein from the stem of a valve of a carburetor, and said actuator comprises an elongate threaded rod received within a threaded through opening in said handle so that opposed ends of said rod are located on either side of said handle to contact an abutment.
