Wick now raised 2mm now you can just see orange appearing at the tip don`t know if it make any difference to the heat output maybe someone can tell me ( have already written a reply but nothing happened must have pressed the wrong button)so i will be brief . This burner will run for 20mins with 5mls of meths no matter what i do which is really too long for what i want. Can anyone tell me how small can a burner/boiler be that will run for 5mins
