Green spark plug

[Mark Bolam]

Is the saw running ok?

It does look like copper oxidation. But doesn't that need moisture to set off the reaction. Was that the spark plug immediately after use? Or did you inspect it a few days later?

Next day. Let it idle down for five minutes after a heavy six litres’ cutting. Two stroke bike riders hit the kill (and pull the clutch in) at full chat to get the truest plug reads. I’ve changed it back over to motomix now. Will have a look after next run.

Oh one with solenoid controlled fueling, too modern for me.

Got bikes. Moved onto 4 strokes years ago. Was taught to blip and stop engine. Didn't really understand why. Thanks.

Going to hijack this thread a wee bit but how often are you guys changing your plugs on your saws? I've put a hoor of an amount through all 3 of mine and never changed one since I started a year ago...

I don't change them unless the saw starts to run rough . So , not very often .
