>It’s not as if internal combustion engines work great in -20C temperatures either. Pretty much every ICE made in the last 40yr, save your $110 lawnmower that was made without a choke to save $0.38, is fine at -10 to -20f so long as it has some semblance of compression. If anything the biggest problem is that batteries don't work so well in the cold so they'll have a really tough time starting an old engine with poor compression (which will be even harder to start in the cold).
