I just installed the dynojet kit like it called for.I used a 134 in the front and a 138 in the rear.I have the clip in the second grove and the mixture screw at 3 turns out.I also put on the gibson exhaust.It will rev up in neutral but when you try to move it splutters and pops and does not want to go.It will run at 3/4 throttle and above though.
