carb seat problems

I had and older Craftsman 6 Hp Rotary mower given to me. Model No.917.387301. It was only used a few timesand is just like new, but was stored with gas in for a couple of years. I took the Carb apart and soaked and cleaned it. My question is should I be able to see the seat in the Inlet Port? I can't see the seat.
It seems like something is in the Inlet Port, sometimes the gas is free flowing(comes out of the air cleaner), sometimes the bowl stays empty. Could the seat have deteriorated and moved up the port and clogged it? If so is there an easy way to get it out?
The flow of gas is fine from the tank to the carb inlet.

Engine Sears model number 143.986000 Tecumseh
THANKS

Looking at your diagrams I guess it is possible that a piece of the seat could be in the inlet hole stopping the gas flow sometimes and other times flooding the carburetor. I do not have compressed air handy so I guess I will just try to fish the pieces out. Any Ideas?
When I dissembled my carburetor It looked exactly like the pictures you sent.
Thanks
