G29 Drive Very Jerky on Takeoff

[coolhuh]

I have a 2007 drive that is very jerky on takeoff and stop. When I give it the gas it is not a smooth takeoff. I checked the throttle cable at the gas pedal and there is no slack, I have it adjusted all it can go at the gas pedal and it still has tension on the cable. Is there another area it can be loosened at?

I have the speed spring on it and the nut on the governor is loosened all the way to try to relieve the tension and stop backfiring, that did not help. The drive clutch moves very smooth and I just tore the driven clutch apart and put a new factory spring on it, it also seems to operate fairly smooth.

Any suggestions?
