Well I checked, and the pin is not adjustable. No biggie, at least for me - I've had no connection issues at all. Oh and remember when I said it didn't whistle? Apparently, my new wick job ruined that feature, and now it whistles like crazy at a very high pitch. I'm using cotton, but this time I used a bit less than last time, just barely touching the 'steps' on either side of the deck instead my previous wick which was kind of folded up and laying across. Won't be doing that again.
