I appreciate the leads my friend. Added some items to the checklist for me. Thank you I’ll report backOk. That's the standard XS Charge w/mechanical advance. It has no known issues with capacitor (the e-advance appears to).
There appears to be a capacitor behind the electrics box and voltage regulator - all presumed ok for now.
I suggest checking timing with strobe light before more carb tuning
Yeah, post #20 above.I think you're going to find the timing pretty close. It wouldn't start so easy and idle nice like it does if the timing was really off. Your off-idle "stumble" appears more like a giant flat spot. That's usually a lean indication. Have you re-jetted, especially the idle circuit (larger pilots)?
