Down power is 4200. I launch at 3800. With what I have it is as low as we can go, secondaries closed all the way, primariy open about 1/4". Any more closed on front and I loose signal to the carb and have some issues coming off. I come off as slow as possible, the screw is set about 1/8 of a turn from fully closed. I creep about 250RPM now. The longer I stay on the more it creeps.

Like I say the car works great usually with the current set up. Just the dang new issue that is causing me fits. Gonna send the box off to have it looked at, might just buy a replacement and keep the old one as a spare, who knows. We are gonna look over the wiring as well this week. Off to Fontana in a couple of weeks so we need to see if we can get it fixed.
