Exactly.
I was worried about the thermacs functioning properly on the air cleaner housings because the bigger one is vacuum operated by that vacuum line, and may not be opening to let enough air in.

If you took the line off of it and put a vacuum pump on the nub... the flue should open and close as you pump it up and release the vacuum. If the car starts much easier with the cover off, it may not be pulling enough air inside.

The little one in the back/bottom of the air cleaner is for cold starts, and moves up and down by vacuum as well.

You can check your base gasket for leaks by spraying a little bit of starting fluid through those little red plastic WD40/brakekleen can nozzle tubes.
spray a little bit on the gasket mating area while it idles, and if the motor starts racing up, it is pulling the ether into gaps.
