clutching gone mild

I have a 1980 EZGO Marathon, that I lifted, and installed a 20 HP Honda Twin, motor in.
The primary clutch, is a Comet 94C Duster, and the driven clutch, is from a Club Car, ( I believe).
From what I have read, the more pucks you add to the Comet clutch, the sooner it will start shifting.
I Have 6 heavy pucks in the clutch, along with the pink spring.
When I take off hard, it shifts up so slow, and then slowly picks up speed.
I've watched it working, and the engine has to rev up to around 2000 rpms before the clutch starts moving. It will shift till the belt is at the top of the clutch. Both clutches shift completely.
Though it is a smooth takeoff, I don't like it. My brothers stock cart, will get me on the start, every time.
When I hit the gas, it should be taking off quickly, not slowly. The belt isn't slipping either, as I can climb hills etc, without it slipping.
My question is, what am I doing wrong.
What spring/puck combo, do I need to make the clutch shift faster?
I'm not worried about spinning the tires at take off, but do want a faster reaction.
If there is another type of primary clutch that will fit a 1 inch shaft, that will work better, I'm listening too.
Thanks for any help.
