Bing carburetors

by Perry Smith in General Tech Discussion 7 years ago

Looking at a Light sport plane today I noticed that the 914 uls had carburetor heat input. I have been under the impression that the Bing carbs do not need carb heat. Is this correct?

Hi Perry,
Is it a 914 turbo or the 912ULS?
Carb heat is a good thing to have. Most don't seem to need it, but there have been some. If you lived in the UK with their weather and humidity verses hot dry Arizona in the US the Arizona people may never need it.
Carb ice does happen, but I don't think it's as frequent as the older Cont. and Lycoming carb setups.

A much better way to go is the hot coolant circulation at the carbs. That is working for you all the time and doesn't impact the carb air temp like a standard hot air induction to the carb throat.

Thanks for the info. I live in the Northeast USA and have a 914 uls non turbo engine for the last 2-5 years. So far have had not a single problem and I fly all year round. When I saw the carb heat on a factory built LSA it made my wonder?
Thanks again, Perry

Zenith says no carb heat needed on a ch701 with a 912 if the plane was built to plans properly or from a kit

If you have individual air filters inside the cowl you are more or less running carb heat all the time and you are running rich. The carbs are pulling in all that hot cowled air. Most engine's we use run better on cool or cold dry air.
