Car not running what is should, need help.

I ordered the kit last week and I was told he got the boxes in yesterday and is shipping orders out. I have the new MP distributor made by Mallory and a Mallory YH advance kit to set the amount of mechanical advance in the distributor and an assortment of springs. The kit has directions as to when the mechanical advance starts and at what rpm it is all in at with different spring combonations. It works really well. I have it set up with 16 degrees in the distributor and 20 initial. Advance starts at 1100 rpm and is all in by 2400rpm.
