A cracked primer bulb. You will need to replace it.
close to primer bulb... has cup shape design
If you are talking about the bulb button it is a primer to get gas to the carburetor if the mower has not run for awhile. Usually not needed to restart a warm mower.

Check the gasket between the air filter backing plate and the carburetor. Usually if that is sucking air then the primer won't work. Your best bet would be to just replace the gasket and possibly the primer bulb as well

You don't. They are not difficult to replace.
You have the letters out of order. HMSK100 for horizontal medium-frame Snow King for a snow thrower engine for dual stage machines. Look to the link at the bottom for a manual; generally destroy the keeper, remove the old bulb and use a socket to drive in the new keeper (and bulb.)

The primer bulb probably needs to be replaced unless either one of the fuel hoses leading in and out of the primer bulb bracket is clogged. Be sure you mark how each fuel line goes before you remove the bulb so you can replace them correctly. Hmmm. Thinking more about it: If the primer worked properly before disassembly, chances are you crossed up the fuel lines when re-installing. Try switching them.
