is it better to run the generator once a month or can it be stored until it is needed.I read it should be run monthly under load so the generator head stays magnetized.Is this true?

Guys we could go round and round with this,    Say-we run a engine at full load for a few minutes, then to be nice guys, we remove the load to allow full airflow over our hot engine.....

Has anyone heard of the effects of "shock cooling".....  I have seen a lot of Franklin, Continental, Pratt and  Lycoming jugs replaced due to cracking from shock cooling...

More food for thought...

I've hear aircraft guys around here refer to it as "super cooling" the engine.  Shock cooling is probably the same thing.  

Not particularly familiar with the phenomenon.  What's the cause and effect of shock cooling?   I assume it has something to do with shutting the engine down too soon after landing.


RedOct:

A similar but much simpler example of what you're talking about is taking a boiled egg out of the cooling water too soon.  Seems fine at first but is soon too hot to hold.  Simple matter of heat dissipation. 

Shock cooling refers to cooling the outside quicker than the inside,   the outside shinks and splits/cracks over the larger inside..
