I just completed my first rebuild of the carb on my 446's B43M carb and have a question about a part that came with the rebuild kit. The part in question is black foam, is about 3/8" across, has a 1/4" hole in it and is approx 1/4" thick. Could this be the packing for the throttle shaft? The shaft packing is obviously listed in the repair and parts manual but I would think that the packing would be more rigid than this piece of foam. Any thoughts would be appreciated.
