The main reason is that the Primus 991 has a different fuel tube burner design compared to the 981, and I also don't like lamps that use a blowtorch-style flame for preheating."
🙏 great input I’ll keep an eye on a great bargain 991 as they are ridiculously expensive 😢 just curious, is there reason why you don’t like a blowtorch preheater?
Blowtorches can easily leak fuel, and if the flame is concentrated on one spot for too long, the glass can overheat unevenly and break easily. This is especially true for the original, old glass, which is very thin. If it breaks, the loss is significant."
