Disconnect the tube fitting from the choke housing and put your finger over the hole and see if it's leaking/pulling vacuum while running?
It should not.
If leaks, time to rebuild carb.
If the tube is passing exhaust, the tube is rotted inside the manifold and needs replaced. Takes a bit of work but can be done. I replaced one.
The choke tube is only supposed to transmit warm air to the choke spring to allow it to expand and change the position of the choke plate. Once it's hot and fully open, it won't matter unless improperly adjusted.
ps: Make sure the spring is not in backward, it's easy to do and won't open.
