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


Jay, just because your engine works well with it does not mean others
will. There are many variables. That is why there is an STC for each
aircraft/engine combination.

Exactly right, and if Cubdriver used autogas with a STC then it should work
as published, no issues with operation.
However, if there is not an STC then all bets are off. I would be surprised
if there was not a STC for the old Cubs
however....

The old Cubs were designed to run on WW-II "combat gas," which was the
mogas issued to run Jeeps, trucks, tanks, etc.

The STC equipment for the Cub is a clip fastened to a pushrod housing
and a note on the gas cap.

Thanks!
And that means that all testing has been done using 87 "octane" mogas and the engine operated completely normally with
no new or additional operating limitations.

Cubdriver said "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." This issue is likely a
mis-adjusted engine mixture or a bad carb than an issue with mogas usage...
