The culmination of my first encounter with a Muka, my dismantling of the pump marathon and some off-forum chats with Norman (@teckguy_58) about the use of canister gas with the stove. What I consider to be the 'ultimate' Soto Muka outfit that should keep me entertained on brew and hot food expeditions for the forseeable future. Two fuel pumps, one of which has yet to have the same repair done on it as was completed in the 'pump dismantled' thread (see latest post in that thread); two generators and fuel hoses; a gas canister connector/valve - oh, and the three sizes of fuel bottles I've accumulated. My first outing HERE with the Muka fuelled on butane convinced me that enlarging the gasoline jet from 0.35mm to 0.45mm (nearly doubling the surface area) would be beneficial and it has proved to be the case, achieving a reliable simmer up to a powerful maximum flame, sustained by inverting the gas cart when it's cold out. 0.45mm jet on the left. The connector for gas cart use. Spares bag includes spare O-rings for that connector and I've removed the plastic cover for the connector, since there's no reason to disconnect hose and control valve when packed away. Changing hose/jet/fuel type is done by installing the relevant generator/jet assembly and hose on the stove body, held in place by the one screw. Must get to work on repairing that second pump ...

Hi John, When it comes to stoves if it isn't one thing it's three. Problems always seem to arrive in 3. I like you have 2 Soto Muka generators. The new one is as it came from Soto USA. The second Soto Muka generator has been altered with a cobbled together fuel hose with valve and the generator orifice has been increased to .45mm. The results are pretty good. Butane. From simmer to high the Soto Muka runs pretty good on Butane. Butane/Propane mix. Propane. Personally for me at least my Soto Muka stove runs better on canister fuel or at least I get better control from simmer to high on canister fuels. My Soto Muka stove is almost overpowered on high with Coleman types of fuels and I can't get it close to a simmer. On Coleman types of fuels all I can get is a low midrange, midrange and high. Cheers, Norman
That was my experience. I could get a lower flame but not a low flame, try as I might. Incidentally, the new Stormbreaker is designed to be dual fuel: petrol/white gasoline and canister gas. I'll be curious to see it. HJ
@hikin_jim Hi Jim, I with you on the new Soto Stormbreaker. I'm looking forward to getting one for myself. It will also be very nice not to have to change out generators so I can run my Muka on canister fuels which as seen runs very well on canister fuels. Let us know when you get one and what you think. Cheers, Norman
A little to add since I was able to get a spare hose/generator assembly as well: Enlarging the jet to just 0.016"/0.406mm works well for straight butane. It simmers well and doesn't lead to underburn on the burner from my brief test of it. While output is a little lower than the Muka on white gas I find that it is a bit of an overpowered stove already for >10" pans and pots already so the lower output is an acceptable compromise. I would assume having the smaller jet where it has a leaner flame has benefits for avoiding/reducing carbon monoxide.
I am still looking for the gas adaptor that comes with the Storebreaker. Were to find a Soto gasadaptor
