[QUOTE="SRAD97750, post: 222891, member: 425"] Sounds like the throttle cable needs adjustment, the slide is not seating correctly, or your carb is not getting enough fuel. If the cable is too tight or caught on something along the path, it'll hold the slide open and cause hard starting, when they do start the idle is too high and not touching the adjustment screw to make a difference. A backwards slide can cause hard starting in a VM (round slide) style carburetor, when they do start, they idle really high (screaming) and is not adjustable. A lean condition will cause high idle, surging, and inability to adjust idle speed in a 2T. Check the float setting. -BIG DAN:thumb: [/QUOTE]
