    Yupp. I deserve that especially after my comments regarding "Is the Computer Plugged in" at the beginning of the thread. 8-[

    I actually do think I'll keep it as is and carefully experiment with it in cold weather.

    Well I figure laughing at myself gives me enough Karma that I can then laugh at others. Good trade off.

    Update....

    I thought I was hooped again...the flame was becoming unstable after about 15 minutes of experimenting. Turns out that I was going through fuel like crazy and was nearly empty again. The stove was putting out more power than the main burner of my Coleman 3 burner which is rated at what 18,000BTU? Fuel consumption was easily 2-3X normal and I got a bit worried. Nice to know these stoves can be hot-rodded, but too scary for my blood.

    I took the jet out and replaced with one reamed again to between .013 and .014. The flame is excellent and very stable, boil time is up to 2:30 or so but the flame doesn't lick around the pot anymore threatening to melt the fill cap. I'll place the oversize jet in my alcohol jet baggy and experiment with an alcohol 111T one of these days.

    My other 111B's are about 2:45-3 minute boilers at normal pump pressure so I figure I am in the acceptable range. The pricker is now smaller than the jet so it won't turn off when cleaned so I worry that carbon may reduce the jet size over time but I'll watch for it.

    Thanks to all.

    Addendium:

    Well the B is holding up pretty well. The new .013-.014 jet allows for awesome power...so much so that I need to be a bit careful. I like using a gas stove as a tent heater (in a floorless tent) in the winter and for this use the hot-rodded B is a god send. Running boiling time tests against my other B's and my best T the bigger jet gives a good 20+ % more heat. At -30 C every bit helps.

    My boil times have gotten faster with the Big Jet B (another sign of some carbon passage perhaps) and I am down to the 2min:15sec range.

    Downside? It goes through gas faster and when used with a pot of snow/ice the fuel tank heats up at full blast. I tend to throttle it down over a pot to avoid popping the pressure valve.

    The funny sparking has stopped and I think the bigger jet let some fouling burn through without clogging. Switching jets the B now works with a standard M jet. It appears I did have some loose carbon that needed to burn through. The combination of heat/quench/tap and carb cleaning burn and big jet burn has appeared to clean everything up.

    It's nice having a bit more power when needed so I am running it with the bigger jet.

    I love these B's but the noise does get tiresome and there lies the charm of the T.
