Did you talk to Scott?
The plugs are showing it's lean. The porcelain looks extremely white and bright.
The ground strap is what indicates if the timing is close or not. By the looks of plug #5, timing is pretty close to where it needs to be.
To me, it looks like the idle is a hair rich and then everything after that is lean.
I think the plug may be a little too hot as well.
Next time you throw plugs in it, just use a drop of
oil on the threads. The copper/nickel seize makes it very hard to read the plugs. That stuff gets everywhere....
