my clutch spring was broken and I just fixed it and when I started the car up the first five tanks it ran great but after that when I would accelerate from idiling the bottom end had little acceleration and sounded super rich and I checked it and it was fine. No matter how rich or lean I tuned the bottom end it did the same thing every time. One thing I did notice is that as soon as I let off the gas the brake engages way more than it is supposed to. I did take the slipper apart and put it back and maybe I missaligned something on accident. My throttle servo seems to be working just fine and my slipper is tightened right. Someone please help.
