Is there supposed to be a hole in the top of the tower (idle circuit?) on this carb (see arrow). I don't remember seeing it before (but then I don't remember lots of things) and I did drop it.  Also Is this one of those tecumseh carbs that is supposed to rattle when you shake it? I cannot hear a rattle.  The carb kit I ordered for it ($7) came today and I was getting ready to install the seat for the float needle when I noticed this. I've never installed a rebuild kit on a carb. Kinda excited to try it. Model # H-30-35077E Serial # 7107 02456
