Hey guys/gals. Can I get some opinions on something? I primarily fly a 99 172R...the airplane I plan on taking my first passengers up over the next couple of weeks.
I've noticed there's a little sputter that comes from the engine at power settings in the 30-60 percent operating range. Never during high power settings. It's happened in the pattern, during descents, and low/slow flight like you'll see in my attached video.
When I was still a student pilot I told my instructor about this, and he believed it's just a symptom of the engine running excessively rich. What do you guys think?
It happens maybe once every 3 flights or so. I have tried leaning on the ground at 1200 RPM as per the amplified procedures. Still happens though. The best way I can describe it is as an unhappy shudder coming from under the cowling that rattles the seats a bit. I decided to take a GoPro with me to capture it.
Here you go...

Pay really close attention to the way it sounds!
