BTW, I've got a great device for preheating. A $20 electric heater
with fan I bought at Kmart that fits beautifully beteween the nose
strut and bottom cowling of my Skyhawk. Nice to find some things
in aviation that can be done cheaply.

Could you be more specific about where you place this during use?

Sure, here are a couple of photos of it:

Turned out to be just blind luck that it fit beneath the cowling so
well. I actually owned the heater before I bought the airplane.
