Cobra atomiser advice needed

[Spinaltwat]

I have a problem with the brass centre pin on my cobra atomiser in that it doesn't stay in place within the tank tube (if that makes sense) I tighten the knarled nut at the top but it rides up out of the insulator. The bottom of the centre pin therefore doesn't always make contact with the firing switch Any ideas how I can get it to stop moving?

just had a look at images of cobra (not got one) has it gat 3 knurled nuts on centre post ?
If so make sure bottom two are tight together and to nut spins free if top nut is tight on post
then new post or nut may be needed (if it doe not thread down without binding...
Hope that makes sense . Nuts and posts here......http://alba-vapours.co.uk/stainless-steel-knurled-nut-set

Thanks for that sparkyjuice it's got just the 2 knurled nuts at the top. I've ordered another centre post from the link you posted unfortunately they only had the stainless steel in stock but I will give it a go and if that is the problem I can get hold of a brass one later on.
