Anybody have any advice about one of these. Using one for quite large areas
of weeds. I am running it on kerosene (heating oil) as I cannot purchase
paraffin locally. Runs ok most of the time but has periods of blowing out
and I find the pressure & valve settings a little critical. Would this be
because of the wrong fuel or because it needs a new jet, all the seals seem
fine.
