I used lamp oil, but whether it was good quality, I do not know. I do not recall trimming wicks, so it could easily be operator error.
They are going to smoke and smell when you first light them up and when you blow them out. When I blow them out, if they continue to glow like a hot ash- they will continue to burn and stink. I wet my finger to wet the wick and make it go out quicker or they will stay there and sizzle and stink for a minute or so. But they shouldn't burn and stink while they are fully lit. If they do- That might mean you have them tuned up a little too high.
