| Subject: | Carb ice on a 912 |
I had to fly the other day in my Zenith 701 when OAT and dew point were both
Zero-degrees. Erring toward caution, I flew high and over landable places
since I don't have carb heat.
This flight got gray matter going. I have heard that the 912ULS isn't very
prone to icing but would like a more definitive answer to the carb icing
prospects in a 912ULS that is inside a cowling. How important is it to have
carb heat if you only fly high mountains in summer months?

The majority of 912ULS's in the world or USA don't have carb heat. Because of the
variable throat slide the Bing 64's are not prone to carb ice. Some say they
have had it, but there are several well authored articles looking for anyone
to actually prove they really had carb ice. I have posted these articles from
the aviation world and well known authors on other sites before. There will be
people who say they had it and pulled carb heat on and the roughness went away,
but other situations can cause engine roughness. The aviation people are still
looking for someone to prove carb ice in the 912ULS.
Carb heat in in many planes using the 912 is more of a recent development over
the last several years. The 912 has been around since late 1989. They haven't
been falling out of the air from carb ice and they fly in every environment in
the world. There are after market carb heating units for the carbs. One is electric
and another hot coolant.
Is it impossible well:
