How's it going?
Expert:  Curtis B. replied 1 year ago.

your throttle butterflies are not seating in the bores. Did you remove the butterfly's from shaft? Loosen the screws on butterflies, and move the throttle and let the butterflies seat, then re-tighten the screws. By butterflies not seating, too much fuel goes through the bore, so you can't control idle.
