-Not a mechanical failure, but I landed in a farm field once when
nature called, then spent about a half hour trying to start the engine
(vapor lock on a very hot summer evening). After near heat exhaustion
from endless hand propping, it finally started and I got home just at
sunset (no electrical system = no lights)

We had one mag on our 1945 Champ that would heat up. Not enough time to
cool down during short stops. Installed a draft tube to blow directly
onto the mag cover solved the problem.
