| Re: Is this Rich lean or correct?
Are all the plugs roughly the same as this one? or did you pick this one specially.
To me it looks fine, I can still make out the white of the porcelian holding the electrode, and there does not look like any buildup on the tip of the electrode. If anything it may be a little rich, but if you only do short journeys plugs can stay dark. If you do a lot of high speed travelling you could try weakening it a notch and see what happens.
If it was darker, no white of the porcelain showing through a black soot coating, then defo too rich etc.
A CO meter is the only real test, |
