Yep, don't throw it away if you can't clear it. I make house calls.
Actually, don't ever throw any of the single port No2 pistons away either, they can really get you out of trouble when you have a loose fitting SureStart.

I have always regarded it is a strange thing that Cox persisted with the port wrench for so many years, I mean after all, their target market was children and young teens if the advertising art was anything to go by. I was a ham fisted kid, and I'm pretty sure all my friends of the same age were no different.
