After a single cylinder overheating an inspection showed lead fouling of one plug from the PTO side.  I then decided to pull the engine and do a complete de-carbon job.

The PTO head had light, soft carbon, with a few deposits of lead.  The bottom ring on this cylinder was slightly stuck on one side.

The mag head was very crusty with carbon.  There was a darker layer under the light layer shown over most of the head.
