trigolf Posted June 9, 2023 Report Share Posted June 9, 2023 Hi all, Just perusing the June Courier and Darren's Herald 1360 article includes a pic of spark plug colours. No implied critisism, but I think the plug labelled ' Optimal' is in fact 'Lean' and one labelled ' Lean' is in fact ' Optimal' ? Link to comment Share on other sites More sharing options...

Chris A Posted June 9, 2023 Report Share Posted June 9, 2023 That plug will take a lot to shift it, there is an 'R' therefore a resistor plug . . . . . 1 Link to comment Share on other sites More sharing options...
