Title: Running Lean?
Post by: Johnny4428 on March 23, 2022, 07:50:29 AM

Does this look excessively lean running?

Yes. Are all four the same John?

Yes pretty consistent across all four Julie.

Are you sure it’s lean. I know it difficult to tell from the photos, but that looks pretty good to me.

Assuming it’s the 550K3, are you running 98 or 100 mains?

I would be happy with that plug colour.

Thanks guys, it’s actually running pretty good, I will maybe just leave as is. Think it’s 98 main.

If you are losing sleep over it go to 100, but I doubt it will make a big difference and the colour looks fine to me.

I find it hard to comment on colors in pics, especially the coloring of plugs. The colors in the pics we produce are never calibrated, so it's always a guess. My first impression is, that the plug shown is slightly on the lean side, but it's thus slightly, that if the colors in the pic were calibrated, I could come to the conclusion it looks fine. Not much help, I'm afraid. :-\
