CHT & mixture control
I have flown certified aircraft (C172, C150) using Lycoming engines and also kit planes using Jabiru & Rotax engines.
I am just wondering why is it:
1. Certified engines (eg. Lycoming) does not have a CHT, but the Jabiru & Rotax (non-certified) do have CHT.
2. Certified engines have manual mixture control but non certified engines have "auto mixture" in the carb. Simplicity of design?
p/s I am just making reference to these engines only, as I'm sure someone out there will say "there are non-certified engines with mixture!"
