You might be able to adjust that by changing the nozzle or the air setting. Not exactly a job for an amateur. You will save lots of money with the right set-up and having your nozzle replaced and adjusted should not be very expensive.
one thing you could do is


take a wire brush and clean the rust


off the burner and that may help.


use a shop vac and remove the excess.


that's something you can do for yourself
stanley cookers have a baffle that you swing across with a lever to give you cooking or hotwater make sure the baffle is in the position you want it , if the boiler has been serviced and set up properly dont touch the burner setting or youll end up with a very badly burning cooker , dangerous and not very efficient resulting in burner lockout
