For those of us that don't or forget to add a dab of water-proof grease to the hot start and choke plungers. This little piece will save you time when it comes time to remove the cable assembly and hopefully free up that plunger. Mind you it works with cable operated plungers not the stock "cap" type that came on the side of earlier models with FCR's. Little added info, if your plugger does jam in there to where some kind of penetrating fluid isn't working. A drill bit, wood screw, locking pliers and mallet or hammer will help. Drill, Blow out copper bits, screw, lock pliers on screw and tap out with hammer.
