Type of gasoline affects performance. I don't know about gas in Norway,but in the US most fuel is oxygenated and requires a richer fuel mix than non oxy fuel.And in theory every spark plug color check should be done with clean plugs.Lower speed part throttle mixtures can be fairly lean for fuel economy and clean running. So long as the engine responds smoothly and doesn't run hot the mixture is ok even if the plug color is on the light side.Full throttle is more critical, main jet size as described by Pete....
