[Wing] Fw: Fw: Carb Heat

[Jaye and Scott Jackson]

My RV-6 is fitted with an Iceman optical carb-ice detector and the short,
Van's heat pipe mounted on the crossover exhaust pipe directly above the FAB
alternate-air inlet.
Several times the ice detector warning has activated and been silenced using
this arrangement for carb heat.
I get virtually no RPM drop at any speed when selecting hot air.
Initially thought the smaller stove would be alright as, unlike the
traditional muffs, it's drawing in air that's already been heated a bit by
passing over the cylinders to get into the lower cowl area.
Plan to instrument my installation this summer to test the temp rise with a
computer motherboard temp sensor.
Worried about a  couple of RV crashes from carb ice that were using this
system..
