Ok - I've got the new hop rubber on and all the parts but can't work out how and when to put the bb in and the position of the hop adjuster so that it has zero hop and the little plastic clip that looks like it located in the outer barrel fits with everything in the right place for assembly. Can anyone advise?

Wrong type of hop-up.  OP is working on the MP9 GBB.

It's the hop adjustment. I have the hop rubber on the inner barrel and then have the black plastic hop adjuster which is a tube with teeth on the end and a slot to drop the ball bearing back into the dimple in the hop rubber. I have dropped the bb back in to the gap and rotated the hop adjuster but can't work out at what position the adjuster needs to be when put back into the outer barrel and what position the little plastic clip should be. The exploded view of the MP9 seems to show the flat of the hop rubber being at the bottom and the hop adjuster being on the upper right but if that is correct which position is the plastic clip? Hope that makes sense?

Ok got the help on a uk forum but thought I'd let other users know. Here are the instructions for refitting the hop and inner barrel components.

The hop rubber has the flat on the bottom edge. The small ball bearing sits on the top. The hop adjuster has the teeth facing to the upper right so that the small circlip fits with the raised bit along the bottom centre of the barrel. Inner barrel pushes in until the hop adjuster is almost all the way into the outer barrel with just a small fraction of the teeth exposed.

No wonder I didn't know what he was taking about.
