Funnily enough the starter rope is broken.
My approach to finally remove the boss was to soak it, leave it under tension and when ever I walk past it give it a tap with a hammer and retention the bolts and leave it again.
Once it started to move, I went back to my 2 legged puller, it still fought me all the way, really have to be patient.
Don't want to strip the centre bolt, so wind him all the way home.

So I take it that this is the decompressor mechanism below.

I imagine it is meant to be held against the lobe in some way and interact with it as it rotates. I will play wit it and try to work it out.
