Yeah, my T-38 would only ignite for a few seconds when fully filled - then it wouldn't do anything (I thought I had a problem filling the thing, so I wasted about half a can of butane just burping, and refilling before I realized that wasn't my issue!) - If your T-38 works for the most part, I would suggest giving it no more than 1 click past the big flame setting
Part of my issue is that my lotus' flame requirements have evolved, it takes a lot more than it used to to vape and it's much harder to combust. When the flame is adequate it hits even better than it used to, so I don't mind.
I don't like the sound of that. Are you noticing that your Lotus seems to favor one side over the rest of the load? It became impossible for me to combust, but it also required a LOT more heat than I remembered to get my Lotus to vape properly. Even still no matter what I did with the torch I couldn't get the load to fully evenly vape.
Even worse, sometimes after my session, I could smell burnt wood - didn't mess with my taste profile of the herb, but I could certainly smell something after using the Lotus.
Upon opening the top to swap the plate with a spare one, I discovered the inner ring had come loose and the inside plate was loose. Emailed MT to confirm, and indeed the cap was dead (Killed from several sessions with excessive heat - most likely when I was trying to vape reclaim at high temperatures and long lung-busting draws - very effective, but apparently too much heat for that cap).
Also note this damage is not covered under warranty. Hopefully they have this issue resolved with the V4 cap (or at least mitigated)
