Ed,
Your memory is mixing you up.
The Erco 310 ("jeep") had NO provision for handling the then-new
experience of carb icing. Fred
Weick's encounter with carb ice in it convinced him of the necessity to
provide carb heat in production
Ercoupes.
From the Ercoupe Instruction Manual, under "Landing":
"When the throttle is fully closed, carburetor air heat is applied
automatically through a linkage connected with the throttle arm. from
half throttle to full throttle, cold air is fed automatically to the
engine."
When so activated, FULL carb heat was applied.
At some point in production, Erco stopped installing the mechanism;
serial number unknown. Today
few coupes have an operable system.
Larry, I'd appreciate some decent pictures of your operable system for
my files.
Cordially,
William R. Bayne

Larry,
What automatic carb heat control?
I remember Fred Weick telling about how he stopped having automatic
carb heat after the almost crash he experienced in, I think, his test
plane the jeep.
The automatic carb heat set itself to a partial setting during a low
power descent, if I remember correctly, and caused icing to occur. If
I recall the story correctly, he was flying to an airport where the
approach was over water and they barely made the runway.
I hadn’t heard of automatic carb heat on a production Coupe. If it
exists, should it be removed? Expert input?
