One way to ell would be to spray carb cleaner at the top of the carbs whilst running to see if that influences anything and could point to a leak.

Yes but if have you wear on the rod in a position other than at tick-over, it might be difficult to detect if the seal is worn just enough to leak a bit at that point.
I'm thinking that maybe the most worn part of the rod is when going on off the throttle.  Clutching at straws here!

Cheers,

It could possibly, but to my mind that's just a scraper seal to stop crap getting to the inner seal. I may be wrong though, it has been known. ;D
