It sounds like the idle/transfer system is at least partially working, but the main circuit is not.

Do the idle mixture screws have any effect? If so, that tells you the idle system is working.

Take the primary side of the carb apart and remove the jets and power valve. Spray some carb cleaner through the jet holes, watching where the spray comes out the other side of the metering block. Then, blast it really good in the opposite direction. Spray the Power valve Channel Restrictions out, too. These are the 2 small holes exposed when the PV is removed.

In the main body, find the passage that lines up with the output of the main well passage in the metering block, and spray it. Carb cleaner should come out the boosters.

Hold the metering block tightly to the carb body (gasket in place) and spray cleaner into the jet holes. The carb spray should exit the boosters.

This proceedure should thoroughly test the main system from blockage, including a mismatched block gasket.
