Never fear, Alan.....

...I am well aware of all the little foibles of my normally aspirated, (carburettor), piston engine in my Cessna 150/152's.
And a quick peek at the terrain map of Western Colorado (Rocky Mountains) tells me that the hills are quite high!....

Anything higher than 5,000 feet above sea level requires careful weakening of the fuel/air mixture to obtain the maximum power, both on high altitude take-off, and high altitude flying!
The same goes for the Carburettor Heat control to prevent icing of the carburettor body, blocking the venturi, and reducing air flow, resulting in a dead engine and a crash!
Many Moons ago, one of my Sim V Chums made me a (XML) little indicator light to place over the heat control knob to warn me when Carb Heat was either on or off...VERY IMPORTANT....Carburettor heating drastically reduces engine power...especially on take-off, when you need it most!
I have also equipped all my baby, carburettor'd Cessna's, with two very useful/important gauges>
(1) Cylinder Head Temperature + Exhaust Gas Temperature.
(2) Manifold Pressure.
A regular peek at them tells me what is going on!
But she still gasps for breath whilst navigating over the Sierra Nevada and Rocky Mountains, Alan!
Paul....I like "little" aeroplanes!...
