'78 Honda CB550K starts up with full choke like a dream. Gets warm and on the way closing choke sputters and dies on throttle. Too lean? Using 100 main jet, and slide pin is on 2nd notch. My air mixture screws are on 1 1/2 turns outwards. Using stock air filter and box. Also, at speed coming off throttle runs backwards, this seems like a timing issue?
My main question is to get the bike off full choke and to have her not sputter and die on throttle.
