Are you using the quiet cap with that Optimus cookset? I noticed that one has to be careful to keep the flame pattern within the ring.
I was going to, but in my tests earlier this week, I noticed that it doesn't seem to work as well with the heat exchanger for some reason. Works exactly the same with all other pots, but with the heat exchanger pot, it seemed to be slower. Might be that I did something wrong. And when there's a pot on top, and simmering is the only goal, it seems as though the roarer is not that loud. Extremely annoying at full blast, but only do that when boiling water, which is fast, so figured I'll just keep the silent burner for the gen 1 Omnifuel, and for the gen 2, go with the included splash guard. By the way: curry all done, and delish!
My findings exactly. I was quite disappointed with boil times using the quiet cap actually. It does however sure quiet things down nicely! I don't feel the need to crank the stove to max all the time, and if you do, the burner bell gets soft and can deform a little where the flame splitter prongs grip it. I found the spring was too tight, which levers the other too prongs up - this deformed the edges of the bell slightly where the flame splitter prongs catch it, and actually pulled the burner bell slightly out of round too - I noticed that by how well the quiet cap sits within the bell (gap around the edge). I pulled the spring, over stretching it a bit to reduce the spring tension. That helped, and running it mostly with the cap, no spreader, I noticed the weight of the cap in operation is slowly reforming the burner bell back round. That's a little adjustment they should be making at the factory IMO... that, or a longer/weaker spring!
