I'm not sure why there's been a lack of responses to other threads, I don't get too involved with the 350/360 stuff due to lack of real knowledge. If these carbs have multiple idle circuit ports at the throttle plate there's a distinct possibility that on of those is clogged. I know the VB carbs on the SOHC 400/450's have 3 sequential ports and it's not uncommon for one of those to plug up. If the slow/idle jet is removable then I'd also be looking at the size of the holes, people use a "jet cleaner" which is actually a fine reamer that's used to clean acetylene torch tips. Keihin jets are nice in that it's straight metric sizing. a#35 jet is .35mm, 100 is 1mm.
