Our Cubs were STC'd for mogas for a year or so, then went to 100LL.
SNIP
More serious for me, sitting in the back seat, was that the engine was
prone to quit. The worst moment was flaring on landing, when the
airstream stopped driving the prop, the prop stopped driving the
engine, and the engine stopped. Most pilots claim that the engine runs
better on mogas, but this was not my experience.

Sorry Dan, but I can't let this lay. You are spreading dangerous and
misleading misinformation.

If your engine was quitting on final, I would have some serious
maintenance done on your Cub -- *or* I'd carefully check the quality
of your fuel. There is NO reason (as in zero, zilch, nada) for your
Cub's 1930s technology engine to run any differently on 87 octane
unleaded mogas -- a fuel FAR closer to what it was designed to use --
than it would on 100 LL.
