    Hi, there are lots of posts about the correct/original jet hole size in the nipples fitted to small petrol stoves, (0.23mm versus 0.32mm).

    I have just been fettling a post PTC Optimus 80 to get it ready to sell. After fettling, these are the flame shots using clean Aspen 4 fuel.

    Both jet sizes result in a good blue flame, but as this is a small burner anyway so I prefer the larger jet.
