I'm not sure on the setup of that car, but if it's like my truck then you have to back out 2 screws evenly 1/8 of a turn at a time. At all cost do them evenly, if not, unless you already have to, you'll be replacing your 2nd gear clutch soon. I read somewhere that if your running to rich you might not be making enough rpm's to get the shift, but I'm not sure about that at all.
