All this reminds me of something, alas recalled only in part...
That rider of fame, Stanley Woods was his name,
with an engine, an ohc master.
"I want ye, says Stan, to tune if ye can,
me motor, to make it go faster..."
"So I take me hammer, me files and a spanner,
and set to, to work with a will.
I take out and feel, both timing wheels,
and generally show off me skill."
