Pulled the plug on my cs590 doing some cleanup today just wondered how this looks? Running 50:1 Klotz/rec 90
Huskihl told me you want the plug color like cardboard. I’m pretty sure he said white was too lean. Just from my experience, which isn’t much I think you’re good. I’m sure others will get you straightened out buddy.
That's not bad...I personally would like to see it a touch darker than that...especially if that was from running in warmer weather...if that was from a 0* day, and you did no carb adjustment, I'd say probably not bad overall.
This saw was bought in July this year and mostly ran on warmer days. Probably has had 7-8 tanks of gas through it
