Dunno, but very interesting.
The FMS stove worked at the start, with good power.
The canister does not seem to have frozen as the other stove worked fine near the end.
The FMS stove did not work later when it was replaced, so the problem was still in the stove.
From this I would say that the jet was getting blocked. Now the jets in these recent Fire Maple stoves are interesting, in that they have a sintered filter stuffed into a cavity in the base of the jet. This is to stop dirt from getting to the tiny jet hole. But there is no obvious way to clean the sintered filter if it collects a lot of dirt! I have had that happen.
What I have done, with great success, is to extract the little filter. It's a plug of tiny brass balls (I think) all sintered together somehow. I used a small stub drill slightly smaller than the rear hole in the jet body for this, but a BS1 centre drill might do fine. Not sure about a BS1 centre drill. The sintered plug comes out fairly easily.
Removing the sintered filter left a cavity in the back of the jet. So I put a *wee* bit of TP I there to act as a filter. The difference is that I can extract the bit of TP in the field and replace it very easily.
As I said before, I used one of these for months with no problems - but the filter in the jet had been modified. I have warned Fire Maple about the problem with the sintered filter, but I have yet to see whether they have taken any notice.
