Good thinking Joe. While I was in the depths of depression ($25!@#%!!) I spied a lawnmower upside down on a neighbours pile of rubbish. They gave it to me, probably felt sorry for me ($25!!). It is now the object of restoration. It is a "Flymo" with a 50mx Briggs and Stratton. They said it seized up after the floods (Mackay 2008). But it still turns and there is compression. I'll post a photo tomorrow under a new thread. Stay tuned for the adventures of sparker!
