It's all trail+error i have never done this before

That would be because you are using the most impractical gas on the planet, butane, it has a very high freezing point which is made worse by it in its self being a refrigerant, the more you use it the colder it gets, reducing pressure as it freezes lol.
Some of the worst offenders are the flat cartridge stoves that take a large butane cartridge that slots in one side, in this weather by the time you have used less than 1/4 of the gas the cartridge freezes and can't be used, a mate of mine out for an evenings radio play had 4 cartridges on the go in -5C 1 in the stove the other 3 in various peoples trousers warming up to be next just to try and boil a kettle , in the mean time I pulled out my trusty coleman, filled it with unleaded and boiled my kettle in around 7 minutes

I only use butane on my camping fridge as it has such a low demand with such a small flame it doesn't give me any issues. Everything else I only use propane. Some bigger equipment I have can put 1/2" of ice on the outside of a propane cylinder in this weather So butane is well out of the equation

Yeah, butane is summer gas really. I only ever use propane (also have a Coleman unleaded cooker, dual burner as well ). You can get butane/propane mix gas cartridges, which I have used before in my little gas heaters, they work quite well, but they can tend to boil off the propane first, leaving just butane which then freezes, but that hasn't happened to me much.

Hi All
I am still playing with A1. I did have another thought automatic inlet valve !! and if possible make her horizontal
then open crank her then make her hit+miss

Andrew pity you can't pick up a cheap Lister D as someone else has had the same idea as you.

Just a short bike ride over the hill to pick it up.

Stu.

Thank's for the link Stu. Lister D's seem to go for more money the me petter a1 cost.
Plus it's good fun trying do it myself with what i have
Andrew

I didn't think you'd be wanting to start another gas conversion it was just to show you how they'd done it.

Stu.

Cheer's Stu now i see what you mean If and when i get this one done next one would be a two stroke conversion to gas :stick lol:

Now that sounds very interesting. Shame I haven't a 2 stroke to spare or I would have loan you it to you to try.
