It didn't take me quite that long - about 25 minutes with the 0-200
Hey, fellow pilots, take it easy on those starter motors okay? That much cranking time could be harmful, if long cooling periods are not being allowed in between start attempts. A rule of thumb (from my C310 days) 30s crank, 1 minute cool, 30s crank, 5 min cool, 30s crank, 30 minutes cool. It varies by engine type, but all starter motors can be over heated.
O-200's are generally a breeze to start cold, if the technique is correct. I often hand prop mine instead of startering it after preheating when it is cold out, and sometimes one swing does it.
I am cautious about percipitation around freezing, but regularly fly at temperatures as low as -20C in the winter. I have flown as low as -40C, but it's not so nice, and any kind of problem usually becomes a big problem. I certainly prefer winter flying to hot summer flying.
