Stop in for a cup of coffee
So for grins, I checked the spark plugs. 2 were a bit wet, the rest a nice caramel color. The last drive was just about 4 miles and a few WOT stomps. I know it should be much more controlled than that, but it does tell me it isn't stupid lean. Also, I have the light silver and light blue springs and black stops. Chart says 18⁰ mechanical added to my initial 18⁰ and all in at about 2000. Maybe the manifold vacuum advance was part of it. So both rich and timing?
