However, I've never seen this taught anywhere. Comments?

There are a lot of these tricks that are not taught, don't know why but it
would be nice if people would share some of these such as landings like these.

The latest that I have used is that I brought my Aero Commander in by using
the primer when the mixture cable broke at the adjustment screw. Just keep
pumping the primer until the engine goes back to running. I imangine the primer
hase many other applications for fuel starvation besides these.
