Great video about reading spark plugs

I have watched quite a few videos on this subject, this one covers a lot of info

Thanks for posting that. I have been dealing with overheating problems, and figured since I put the jetting back to stock and it was running fine, that couldn't be the problem. I really didn't know how to read the plugs properly. I pulled a plug tonight and based on the video it is lean, and I need a little more timing. I bumped the primary jets one size, so we'll see how it works out.

That’s not lean to me. It’s a touch rich at idle.

I have no idea what WOT is because I can’t see down inside the plug.
