heads not level - thoughts please :-)

yep those nozzles you have are standard. The bore on mine and the hexagonal bit and the thread length are all larger.
hence my problem :-)

I can pay about £15 for one from the states. And that's probably what i'll have to do. Or see if dave can drill out the main shaft to fit my teflon tube, in which case I can probably just buy cheap ones.
