actually, if you build a wooden box, of proper dimensions, and line it
with reflecting tin foil (awright, so it's called aluminum foil
nowadays!), and maybe even some insulation behind the foil, you can
put a 60-watt bulb in there and it'll keep a nice temperature under
the engine. but you need to make sure the box is quite close to the
engine ... a gap of no more than, say, 1/4 inch (5-6mm). you'd be
surprised at the amount of heat a bulb like that can put out. :)
