[QUOTE="BrounHownd, post: 481897, member: 30222"] As an update, went through the timing and throttle linkage setup per the manual. Timing was close, but not quite there. Linkages were micky-moused and pretty far off. Thinking previous owner or his cut rate "tech" tried to adjust away a deeper issue. Also pulled the coils and CDI and put a meter to them. Coil primary is reading about 4x spec resistance, and all CDI resistances measured from the trigger wire (white red striped) with the red lead we're 2-3x the high end of spec. All others were good. If the CDI isn't triggering at the right time that could cause some spark strength and timing issues as well, I'd imagine. Gonna see of those parts resolve the issue and if not rebuild the carbs again. If nothing else, I'll have a spare coil and CDI in the toolbox. [/QUOTE]
