Carbon flakes in cylinders ?

[kyron4]

Pulled the plugs on my '56 lightwin to fog them and I could see small brown flakes on a light film of oil of on the piston tops. I could wipe them off with a q-tip, some on outer edge of plugs too. I assume it's carbon. I ran seafoam in every tank this year and run 20:1 mix. Is this normal ? Anything to worry about ?-Thanks

Nothing to worry about there, it's just the Sea Foam doing it's job. You might be just a touch heavy with the oil but, if it's running good, leave it alone.
