Thank you. Am super stoned and just watched a plane fly overhead on a dark and coldish night. Started wondering what the start up procedure is in cold weather and how long does it take to warm up and engine. You covered it all🤟 FANTASTIC! 😁 And I know nothing about starting an engine either, or anything else about flying but would love to learn. So amazing.
In the carburetor, you have what is called The Venturi Effect; where the air from the outside is compressed into a low pressure area which squeezes moisture out of the air. This residual moisture attaches to the nearest metallic surfaces it can find and freezes instantly just after it exits the Venturi tunnel--the part where the fuel is mixed with the air. As the moisture freezes just after the tunnel, it builds up on the butterfly valve, and the surrounding walls; which sophicate the engine. Therefore decreases RPM, Power, and *Performance*. I know it's been 8 months since you posted this but I'm sure you had found the answer later on.
It depends. Ideally a normal takeoff should be done somewhere rich of peak for engine reliability. When flying at high altitudes, this would mean bringing the mixture out by about a half inch to an inch in most cases. Some airplanes are more prone is fowling than others, and if you are renting, consult the owner about that. When doing a short-field takeoff, many airplanes should be leaned at max power while holding brakes to just rich of peak, or best power. Keep in mine that colder temperatures would mean denser air. Since fuel/air mixture is a gravimetric ratio, this means that a richer apparent mixture would be necessary. Effectively, you have a lower density altitude, which governs how the airplane's engine behaves. Where I fly, the average elevation is around 3500' so slightly leaning for takeoff is commonplace. If your engine is running rough at high power settings and your mixture is full in, you could try leaning it a few turns at a time and see how the engine starts behaving. An especially rich engine will act somewhat similar to a very lean running engine. Of course, keep in mind that carb heat would significantly enrich the mixture if you are already flying at higher altitudes. That's my 2 cents on the matter. Make sure to contact a certified flight instructor and you airplane's POH whenever there is any doubt. For legal reasons, nothing I have said here is to be taken as any form of flight instruction, and is merely my experience. Use it as you may.

FANTASTIC!

Don't even know how to learn or how much it costs.
❤❤❤❤ cute plane 🤗🤗🤗🤗🤗😍😍😍😍
Who else was waiting for the landing?
Great video & tips!
Thanks for the info. A cold front blew in today down here in Atlanta and I'll be flying in temps below 20 degrees tomorrow.
I enjoyed your video. You did a good job in covering the subject. As long as you dress for the elements, winter flight is great fun.
very informative!
Could you please describe how icing can affect the performance of aircraft engine

first Song???
I don't like to put mixture fully in prior T/O...

Now I feel too dumb to learn after reading this post🤦😄
Engine damage due to fast no power "let downs"...???? Rubbish!
