Idle is absolutely fine it was all over the place for about half hour then stuck on800 been fine since. I was told u can smooth the ramps but do not remove any material or it will never idle again! So that's what I did. I concentrated more on other areas like the shaft an disc, removing excess screw thread an countersinking the heads. I then removed material from anywhere that wasn't the peak of the ramp or around the throttle disc. Before I did this the car felt sluggish when flooring it from low speeds. It definitely snaps alto more now but not annoyingly so. I've yet to venture further wit
