alan may be right, but on other multifuel stoves I have, the white gas and compressed gas jets are different from the kerosene jet. Way back, before I looked, got surprised, then talked to a couple stove manufacturers, I thought the white gas jet would be the smaller diameter. But no, it turns out to be the other way around - the kerosene jet is a smaller diameter hole, apparently because the molecule is bigger, so the energy stored is greater per unit volume. This is true for my Primus MFS and all the MSR stoves I have (XGK, Whisperlite International, Dragonfly), as well as the Coleman Peak One International. The Primus MFS uses the same jet for white gas and butane/propane canisters, but a slightly smaller opening jet for kerosene. The jets for most of my MSR stoves are marked "G" for white gas and "K" for kerosene (one was unmarked on the white gas jet). I never owned an Optimus multifuel and never looked closely at other people's.
