I have no idea what this is or anything about TAV's but I yanked it off an old engine. It says 20 and 5/8 on it so I assume it's form a #20 with 5/8 bore. No idea what it's worth if anything, but I thought I wold throw it on here. Since I have to put a price on it, how's 30 bucks sound? You can laugh at me now, or laugh at me later.
