Spark plug

how does this look. Did a muffler mod and want to make sure I'm safe. It's a light brown color. Seems to be running great, 4stroke and cleans up in the cut

Photo is too dark to tell. If saw is tuned as you stated I'm sure it's fine. I wouldn't worry about what the plug looks like.

I agree!

Here's how to read a plug on a chainsaw-

warm the saw, install an new plug, bury the saw in a log, cut the power mid-cut, pull the plug, look at the base of the insulator....that's it. Otherwise, you are looking at a compilation of run time on a plug, not the most immediate run history. It could have been running lean in the last two minutes of the piston's life. The plug may show a nice Carhartt tan, but the saw is toast.
