Would the colder outside air be denser (like the writer!) and therefore cause a leaner mixture for a given needle setting compared to taking air from inside the cowl as usual?
With or without proper cowl baffling around the engine what temp changes in incoming airflow can be expected in the milliseconds it takes from air entry to it disappearing down the carburetor while the aeroplane is in flight? i've never worried about it on methanol engines but for this big saito gas twin i think i need to know,it gets real hot in summer here.Has anyone here used a data logger with sensors under each plug to measure cylinder temps? i'm going to look at the eagle tree system and any others that are out there.
Sr good point about drawing carby air from inside the fuselage.On the 50cc edge 540v3 there is a huge cannister tunnel under the electronics tray i can draw from.Cheers.
ps do you need to combine a data logger with a gps to get meaningful inflight readings?
