Well, you'll (almost) never burn up a piston or valve with a rich engine.
That aside, 2 & 3 certainly do look more than a bit fat.
Are they gapped properly?
Is the valve lash set correctly, or at least equally across all 4 cylinders?
And, just at a reach, do you happen to have the vac lines on #1 and #4 for brake and crank ventilation? (this would explain why those two are leaner than the others as thre airflow is slightly different)
The closeup of #3 shows something goofy going on at the electrode, or is that a bunny turd that got stuck there? (might just need new plugs :shrug: )
