idle problem with long duration cam

I realize its not that off. But it seems like it could idle a little better. I am wondering if it needs more convertor as it does tend to pull down the idle to much when I put it in gear. It actually idles more at 1000rpm. Depending on weather.I have played with opening the rear throttle blades some, so I dont uncover the slots. And also added small holes on the primary blades. No change. Have gone back to a stock setup on my 750 double pumper.
