[Titanaircraft] Re: Flying in cold weather

This I find interesting (no problems down to 10F) because several 912 engines I've had, both 80 an 100hp have convinced me to plan on either pre-heat or boost below freezing and if I'm going to overnight away from hydro take along a propane preheater. What are the secrets in addition to minimum plug gap and good battery for starting without assist at 10F?
I do agree that it is much easier on the engine to preheat at lower temps but I can't help but look at my old Ford Escort with 300000 km that starts right up in almost any weather even when I've forgotten to plug it in and still doesn't burn a drop of oil.
