I have a kero stove oven on my boat and it works great. I use a bike pump to pressurize it.
Be sure to get the burners well and truly pre heated with the metho before you turn on the kero or it can flare up. Always use metho to light it if you can because you will find it cleaner and less chance of big flare ups. Check to see if the knobs prick the jets in the burners when you turn them full on. This allows you to clean carbon from the jet, If the jets are dirty it wont burn smoothly nor develop full heat.
I pressurize to appox 75kpa and have found that the amount of kero in the tank changes the time the pressure lasts. When using the oven I have found that heat warms the kero tank and starts sort of a self pressurizing effect.
Remember to release the pressure from the tank when you finish so you don't get kero weeping out of the burners.
Its all very similar to a Tilley Lamp.
