There were block heaters for L model gravelys. Apparently they didn't work all that well, and also had a tendency to catch fire :Stop:
I've run strap start gravelys in quite cold weather. I'd always choke it all the way, pull it once, then back the choke off to 1/2 to 2/3, then pull again. I could almost always get it to fire on the second or third pull like that.
I've also used the light bulb trick. A 60-watt bulb throws off quite a bit of heat. To enhance, the effect, ditto Dayton_king, throw a blanket over the whole works to hold the heat in.
