Default Sheen flame guns: question

Hello all

I have just inherited a very old Sheen brand paraffin flame gun with a hood
and wheels.

No instruction manual of course but I relied on my Boy Scout prowess with a
Primus stove.

It seems that you have to heat the paraffin filled coil with the fuel
soaked asbestos wick until it reaches a suitable working temperature.

After filling it with paraffin and soaking the wick with fuel I lit it and
pumped it up to 20psi with the fuel valve shut.

When it started roaring away. I opened the fuel valve and started to burn a
patch of weedy ground .

However after about 20 minutes it "goes out " and a huge cloud of unburnt
vapour pours out.

I have taken out the nozzle and cleaned it out but it continues to go out
after 20 minutes.

The pressure is kept around the 20psi mark .Should it be higher or lower ?

Has anyone any suggestions as to why it works ok just for short periods ?
