In his book Where Is Joe Merchant, Jimmy Buffet referenced this technique using the good engine and some dock line on a Grumman seaplane (Goose or Alby...can't remember which) to start the other side.
Grandpa used to talk about engines with hand cranks, shotgun type shell starters, and a bungee attached to a boot that would fit over the prop tip. Three or four guys would start running away from the plane and at some point the strength of the bungee would overcome the compression and the prop would turn...
He did mention it was important to DUCK and doge the boot as it came flying by. Not his favorite starting system.
A Mexican told me one time "...all your regulations have made Americans afraid to do anything. That's why no one can do anything and nothing gets done."
The English came up with a very effective way to start early aircraft engines in and after WWI -- It is called a Hucks starter. The one pictured is in the Shuttleworth Collection at Old Warden, Bedfordshire, England: http://www.shuttleworth.org/

Here is a softball for 180Marty; According to the video, Brazil ag planes run on 100% Ethanol, we cant make our lawnmowers run right on E10. Are the Brazilians smarter than us? Or is it their women just look better in Bikinis?;-)
