I'd be interested in any schemes you may have developed for
pre-heating your engine.

One idea I heard was to use flex ducting to direct car exhaust into
the cowling; that does present CO concerns, but on could leave the a/c
doors open. - Mike

When I had my rebel tied down outside I used a " Mr. heater" It's a
radiant heater that screws onto a BBQ tank. I built a box around just
the heater part out of aluminum and 2 galvanized furnace pipes coming
out of the top. wrapped it all up in reflective bubble pack
insulation. Just light it up stick a tube in each cowl inlet throw a
blanket over the cowl and wait 20-30 min. and the cylinders would be
warm to touch. Now that I have a hangar I can just plug in an electric
heater. I even have it on a timer so if I know when I'm going to fly I
can have the plane ready.
