What lubricant do you use that won't burn off under the high heat of the
exhaust manifold ?

As I recall, we used things like Carburetor cleaner spray, or solvents, when the engine was cold.  The idea was to keep the carbon and rust from seizing the things up in the first place.  you can also use stuff like powdered graphite or lock de-icer which have graphite in suspension.  This carries the graphite into the shaft and leaves it after the solvent evaporates.

 

Don't use plain oil, because it will cook into carbon and make things worse.

 

The best policy is to get it free, and keep moving it every week or so to keep it free.
