@janders Found there is a leak at the bottom from the gland nut. It is stuck and a do not want to use force as the brass is quite soft. Will apply WD 40 and leave it for a few days.
Got the flame regulating rod out tonight. The end of the rod looks different from the others I've seen here. But the gland nut is still "frozen" .Made up a mixture of ATF and Aceton which I applied. Hopefully something will happen soon. Have a nice weekend Bjørn
