I have a hard time getting it started at 25F.  I turn on the cold start
switch, put the mixture at 3 O'clock, hit the primer button about 4-6
times and open the throttle to 1/2.  When it starts sputtering I switch
off the cold start and pull the throttle back at the same time.
Sometimes it runs for about 20-30 seconds and dies and I repeat the
process.  If the battery is too low by then I put on a charger for an
extra 20 amps.  If I have to shut it down to remove the charger, I let
it warm up for 5 minutes or so.  I'm looking forward to seeing other
techniques. This one needs improvement.  I'll try Larry's technique of
pulling 6 blades.

My cold oil pressure reads 99 which I assume is the limit on the 100
psi sensor and I don't think I've ever seen it below 70.  In flight at
5900 rpm it reads 86 psi.  I haven't calibrated the gauge.  I'm using
the default EM2 settings.
