Help - need to adjust my Sturmey Archer XRF8

I have > 1400mi on my IGH. Had it adjusted once last year, now it's acting up again. I want to learn how to do this myself.

Symptoms:

Gears 1-5 are fine.
Gear 6 is practically nonexistent. Usually fails to engage, when it does engage, it slips out very easily.
Gear 7 engages OK but slips a lot
Gear 8 is fine.

This an XRF8 IGH that came factory installed on my Downtube Mini. Downtube's instructions are to line up the little yellow arrow on the pulley between the two yellow notches when the bike is in 4th gear.

Well, I checked that and it's already lined up perfectly.

Any ideas on what to try now? Thanks!

I found that to consistently get all 8 gears, I had to adjust the cable tension noticeably differently to the instructions. YMMV.

It might be related to the cable being sticky or the housing being crimped. If you fold your Downtube often, then perhaps the cable is a little compromised. It looks like it's adjusted perfectly. I'd take the cable out of the housing, clean it well, check the housing carefully for crimps, then use some tri-flo (teflon lubricant) on the cable with a squirt into the housing before putting it all back together. I believe SA uses spiral housing, which tends to compress a little, so it's not quite as accurate as the parallel housing used for indexed derailleurs. Maybe change to new SIS cable housing if all else fails?

Thanks for the responses! Ill try experimenting with different arrow positions, and if that doesn't work, detach and disassemble the shifter cable.

Followup. Didn't see anything visibly wrong with the shifter cable, so I brought it to my LBS. 2 minutes of twiddling with the barrel adjuster near the grip shift end of the cable, and it's shifting perfectly now. :-)

Note the exact alignment positions of the two marks at the hub that has it shifting well so you can duplicate it if things go out of adjustment again. From the photo it appears that the one alignment mark is fairly wide, giving a range of adjustment. Obviously though on your hub adjustment is more critical than that.
