I know thars very old topic but can you tell me what is "pinking" What's that mean?

It's a little tinkling noise from the engine under load, "pink, pink, pink,.......".

It's the result of the fuel mixture igniting due to excessive heat in the cylinder before the spark plug sparks. As it happens while the piston is still going up it causes very high loads on the piston, small end, etc and a loss of power.

The root causes are excessively high compression ratio, poor quality (low octane) fuel or a build-up of carbon in the combustion chamber.
