Yes you can try opening up on the idle mixture screws. If you need to go more than 1/2 turn from where they are now there is something else wrong. When you put the pump back on did you make sure you got all the hoses hooked up right? I believe there is a vacuum line from the control unit of the pump to the vacuum temprature switch up on the intake manifold.
