Thanks to marco and dave.
Woke up in the middle of the night to figure out that the vacuum hose seen in the picture lower left is connected to a vent for the fuel bowl. I will be replacing the hoses and checking the canister to see that it is operating properly, after I clean the fuel bowl, jets and discharge nozzle AGAIN. I will post whether it fixes or not. Snowing outside today though so may have to wait until tomorrow.
THANKS SO MUCH.
