It sounds like you positioned the swashplate too high and have less positive pitch than you had with the original swashplate. With the throttle stick all the way down, the blades should be level with the flybar (0 pitch). Crank the adjusters on all three servo arms until you achieve this. Here is a link with great info on setting up the rotors:

Hope this helps, the above link helped me get things tuned after I rebuilt everything after a serious crunch....
