Who here is good at reading spark plugs?

If it were me the Leakdown gauge is coming out of the cabinet. Simple way to rule out any issues mechically IMO and super easy with shaft Rockers. I like to get the easy stuff checked off.

Have you ever considered a AFR gauge? It won't help you with each cylinder however it does give the overall AFR. Since a couple of those plugs look fat something you can have done and I don't know what a shop charges but a smoke machine really eliminates the vacuum leak issue. But I am not sure that would be at the top of my list to get done....
