Got the Hershey find of the kerosene tail lamp on Nellie. Was a $10 lamp missing its font, but had one of those, and its a brass top, red lens one too.
So filled the font with sweet smelling torch lamp oil, and added a flame. Nice, but took a ride to the post office at dark, and the tail lamp blew out on the way.
Now the side lamp stayed lit ? What gives?
So lengthened the cotton wick, and when home, about 20mph, but that kerosene tail lamp was blown out again.
Guess I'll have to count on the electric red taillamps on the rear when T'ing in the dark
Probably could add a baffle in the stack???
If it has the holes around the base of the chimney, that why it went out, too much air movement. That is the reason the lamps were changed to get rid of the holes there.
It is the foul air from the exhaust that is smothering the flame.
My front lamps go out but the back one stays lit, The doors are a really bad fit on mine though.
AHA!!! I have the answer to your dilemma.
Having the tail light (nd/or the sidelights) was a common problem with the "new" style (eg non-square) taillights - the new shape, combined with the shape of the "reflector case" and the wind coming off the back of the car (was really bad with the tourings) would blow the lamps out. They experimented from mid-late '15 through about mid-'17 (IIRC) with different reflector case shapes (square vs round, shallow VS deep, etc.) and ended up also putting a different design of baffling in the chimneys.
My solution was to re-baffle my 2 sidelights, which keeps them lit. My taillight, well, I didn't want to tear into it and bugger it up, so built a socket base to fit where the burner went (so I could convert it back) and wired a 28 volt (aviation) lamp to the headlight circuit...
Oh yeah, while the TL modification may not be authentic (you can see the wire going to the Kerosene Font if you look closely) the mag current gives it just enough "flicker" to look like a flame. (Probably means I have a weak magnet or 2... )... and I've yet to have the wind extinguish that flame!
I find that "Ultra Pure" brand lamp oil stays lit better than kerosene. Smells great too and does not smoke.
I have used "Ultra Pure" lamp oil for years. It works great in my 14 Touring and I have never had one of the lamps blow out. Nothing works well on my speedster with 15 lamps on it.
