1952 200 deluxe with 327ci dies when warm

I have a 1952 200 deluxe with a 327ci engine, 2brl carburetor 928S. when the car is warmed up it dies. Compression test seems fine. vacuum is with in specs.
Odd thing is when I remove the aftermarket air cleaner. the engine dies. if I set up with air cleaner off and put it back on the idle is way too fast. any ideas? should I buy a rebuilt carb?
