Second lighting observations. In this stove, Sterno paste (jelled alcohol) in the primer cup is perfect. It leaves a residue behind, but it stays put and it can be shaped into a mound for more volume. This stuff is awsome. It burns really hot. As soon as the stove is lit and can sustain itself on kerosene fuel, it gets red hot. The sterno residue burns away. "There is nothing like the smell of Napalm in the morning." Fuel: Add a small amount of fuel injector cleaner to the fuel. I found that lighting the stove worked well this way. I noticed some use a 30/70 petrol to kerosene mix. You can get by with a lot of kerosene and a small amount of fuel injector cleaner. I added about 20 ml to the bottle. I used this method with diesel (50-100 ml) in a different stove in the past. Sterno paste is great, but it leaves a residue. This is not a problem with the stove here, but it is really hard to clean off brass parts on a Butterfly pressure stove. The rule of thumb is if the primer cup sits in the fire, the residue goes away. If it sits under a burner, you will be painfully reminded of it every time you light the stove. It leaves its ugly mark in the primer cup. This stove is like using a flame thrower. It would be nice for boiling water rapidly or cooking in a wok. If you want to simmer, use a Butterfly pressure stove. They are much better for that. Overall, I like the Butterfly stove more than this one.
