BORING, IT IS NOT! (OR IS IT?)
In a previous blog – well, over 18 months ago to be precise – I mentioned a rebore of Little Willie's cylinder was overdue. Later on, I decided to complete the reassembly and see how it went. It went flattish-like and tinkled like mad, and it sounded as if the piston was hitting the bottom of the cylinder on the down-stroke.
Looking through my extensive collection of spares I located a spare cylinder. There was no visible degree of wear, no ridge at the top and no scratches, so it seemed a likely candidate to replace that already in place on my D7. Now the question arises, what size is it as it's bigger than the original and must've been bored out at some time.
Anyone have any ideas?
