Thanks. I may have figured it out. The ist gear "click" on the lever is
somewhat elusive, and it takes a subtle touch to get the lever to click
into the 1st position and reach the detente. I think that the lever's
internals may be a bit worn. The hub itself seems to be fine.
If this latest adjust
You're sure you have the cable properly tensioned (e.g., no slack in 3rd gear)?
It sounds like the shift lever is rotated too far to get the hub into 1st gear,
and slips back into the "normal" 1st position.
Also, you're certain it's the correct shifter?
You could try putting a friction lever on
