If you are using small camping gas bottles you wont get the output
you desire. You need a calor gas bottle I thing around 13KG, attach
this to a gas regulator (as if you were going to use a blowlamp) and
a hose to your burner this will give the the required pressure. and a
stronger flame alowing the presure to rise. the bottle of gas can be
bolted to a riding trolly behind the driver.
