I'm not a pilot, but it's fascinating to see the temperature drop through the carburetor venturi on the monitor. One can easily see how carb icing can happen sans heat when the dew point is near freezing. It's a little known fact, but snowblower engines are also prone to carb icing given the way that snowblowers operate near freezing and in humid conditions under high power settings. Many snowblower owners don't give it a thought as to why the small engines on their machines have that metal box around the carb. It's not to make the carb harder to get to, but rather to pull some of the intake air over the hot muffler on the way in to keep the carb throat from icing. Unlike a plane, a snowblower's carb heat is fixed and non-adjustible. I realize that snowblowers probably aren't a big item around the Austin area, but I thought I'd share anyhow.

I never gave my snowblower too much of a thought but it makes sense. I just know I appreciate that beast when the snow starts flying and it's really cold and windy. Learn something new everyday.

I'm also a pilot in Texas (Houston area) and fly around here occasionally. Carb ice can potentially be a problem around here given the right conditions. But I regress..... I've never operated a snowblower!! But, carb ice is still carb ice no matter where you live!! I never thought about it before!! Thanks for the insight!! Stay warm my northern friend!!

“Sometimes it’s the people no one imagines anything of, who do things no one can imagine.” Alan Turing, who cracked the Enigma codes with his ‘computer’. Josh, that’s what you are all about. You’ve come a long way and you are gifted with talents many people struggle all their lives to achieve. You will do great things in life. My high school Civics teacher told me I’d never amount to much, never graduate from college ( I was not inspired by Civics & a little lazy of a student in that area). I met him on the street by accident after I graduated from college, had been accepted into dental school, and have had a great career...and now I’m a pilot and AGI & IGI, finishing my IR & CR, maybe CFI (well at least I passed all the writtens). Near retirement and having loads of fun. Keep the spirit alive! I might even start a You Tube channel call Air Alakazam this year; just have to learn how. 😎🛫

Just put some on her, take some pictures. Then you can take them off. Sorry I love Cessna Skyhawks "with wheel pants" and Cessna Seaplanes, I grew up with them.

Thanks for showing off your new MVP-50 Josh! As you, I had to prioritize my upgrades in phases. My phase1 was dual G5's, ADS-B in/out, WAAS and an engine monitor (Insight Twin G4). I'm flying down to Tx today to pick her up from Phase 2: STEC 3100 autopilot upgrade. I'm thinking Phase 3 will be upgrading my 20 year old GPS's (going to decide on that at Sun n Fun coming up) and my Phase 4 will probably be something to replace all my old engine instruments. I will add EI to the list. Thanks again! :)

Was the plane a Cessna 172 ? How long was the flight ? Did you have to do ground school first before the first flight? Are going to take flying lessons now?

Im an instructor and we upgraded all of our fleet with the mvp. 50. Its pretty great, especially for leaning. Ive never had a problem with them until about three days ago where every gage failed and read "COMM" in all red. Another flaw is that you can't find out what causes the red warning light in flight, you need a usb with a computer. One time in flight the red light flashed for a few seconds and couldn't find out what was causing it because everything was in the green. Other than that its awesome.

To demonstrate "shock cooling", fill a cheap glass beer mug with boiling hot water. let it stabilize for about 30 second. Pour out the hot water, then fill it with ice cold water. Do this over a sink, and watch the glass crack or shatter. Your engine is "cast" metal, meaning it has the very similar characteristics as glass. Shock cooling is very real, and this little experiment where you sacrifice a cheap mug should convince anyone of that.

Peter, while I'll agree with your assessment, the real issue is that you have 'hot water' in a container designed for hot water, and then you empty it and pour in cooler water. The issue isn't as dramatic as your demonstration would show, and this is the reason why pilots don't think about it. The engine is designed to stand the temps and pressures it's under, BUT, repeated cycling between 'hot' and 'less hot/cool' will cause stress fractures and cracks. Really, when was the last time you, or anyone, saw a cylinder shatter? It just doesn't happen, which is why pilots don't think about thermal stress. Understand, I'm not disagreeing with you, we all need to be cognizant of thermal issues with the engine, and shock cooling, i.e., over 50 degrees per minute qualifies, but most people don't have that information in front of them, and hence don't think about it.

To my knowledge there have been no laboratory tests which demonstrate that repeated rapid cooling causes damage to an otherwise healthy engine, so it remains a theory used to explain symptoms seen in the field and a hotly contested topic. Jump plane pilots are among the most ardent supporters of the shock-cooling-is-a-myth camp, since they run their planes in precisely the modes they are told will ruin their engines, and suffer no such consequence. I don't actually have an opinion either way since I've never seen solid data to support either claim. However, avoiding the conditions that are claimed to cause it is quite easy under normal flight profiles, so I do. Our JPI EDM 730 has a "CLD" meter which is similar to Josh's S.COOL meter.

@@hempelcx I would be curious to see if the studies have been done. There is a lot of circumstantial evidence that supports the theory, but I would like to see a regimented test. Of course, it might take thousands of hours to do, so I wouldn't expect it any time soon. :) Three same debate as ROP vs LOP.

Gary C ROP vs LOP has been studied in a lab using I believe a Lyc IO540 and showed conclusively that properly leaned LOP runs cooler and is consistently better for the cylinders in all aspects. That requires fairly evenly tuned injectors, so people often swap out for GAMIjectors to get there. Personally I have trouble running LOP in our IO360 engine and I also don't like to fly that slow, so we typically run ROP staying rich of best power.
