I had a bit of time to play today and started with the big bunsen burner to heat up the cast housing and maybe help release more crap or even the needle. It proved to be interesting with a bit of heat soon it ignited some crap inside the cap and a pair of flames were shooting out. It burnt for a while and at the same time smoke was coming out the top end like a chimney. I have made a tool to lightly drive onto the top of the needle which in turns grips it and I hoped it would then lift the needle out, not yet. But I did find what appeared to be grease inside now after the heat and burn out. It has not let go as yet but tomorrow is another day as a customer rang me and was in the deep poo stuff again so he turned up and I had to fix his problems and that was the end of play time.
