I think I'm nearly at the same conclusion as you Mick!
Now, mine isn't shooting too bad at the moment but accuracy is not near what it should be with any jsb, (lets face it if your gun will shoot them they are the best) so before I take it apart again I'm going to clean the barrel then shoot some more groups.

Maybe a good plan, sir.
Now, I've never cleaned a barrel. Not felt the need to. But Jim Tyler, in an article a couple of months ago, explained why it can often be a good idea if accuracy isn't as expected when using a soft pellet (like the JSB) if the barrel has had other, harder pellets through it.
I'm sure you're au fait with the procedure, making sure you lead it back in afterwards.
Hope it works and be sure to report back.
