Meths will burn cleaner, rather that sooty, though it seems the procedure 
is have fuel in the tank, valve closed, pump it a little, open valve to 
let fuel down and onto the wick, close valve, light the wick and wait 
(pumping up in the mean time) until the fuel in the coil really starts to 
va****ise and roar, the open the valve and away you go.

Ouch, road diesel would have been 40p/l cheaper!

Any nuts to nip up? There might be an O ring in there that has dried and 
shrunk but will now be well oiled.

You'll not get a small flame from it.  B-)  Think of something a foot long

and the diameter of the nose... pointy, stable and basicly blue with some 
small yellow flashes should be attainable. It is a bit of balancing act 
between valve opening and pressure. Best to try and only adjust one of 
pressure or valve at a time. But the pressure will drop as fuel is used so

pick a valve open position that you can repeat and the adjust pressure to 
make it run nicely.

Flaring (large or big yellow flame plumes) is indicative of too much fuel 
and if difficult to bring under control by adjusting the valve and/or 
pressure may indicate a worn jet.
