Yep.

Swap these two around, it'll cool while you pump. Don't know about the 
pressure. I might go for 50% to start with then adjust once I've gained 
experience.

Not sure that the bits will get hot enough hot over a barbie. I'd expect 
to find a little indentation or spoon to hold about a table spoon full of 
meths some where near the jet/coiled pipe.

Light the meths and when it's almost all burnt turn on the valve slowly, 
the burning meths should ignite the vapour.

You way runs the very real risk of either have a jet of hot(ish) liquid 
parafin or clouds of vapour (whumpf!) or something inbetween (20' flame 
thrower).

Yep, and keep it pumped up.

Check the jet is clear. You really need a proper pricker for that.
