Possible Carb Ice at 10,000 feet in my Cessna 150

I was humming along at 9,500 for an hour or so and noticed my RPMs were noticibly falling off.

I had this happen yesterday. I'd been flying in clouds and rain at 4, 000 all day. Then, it was clear skies at 8, 000, and she did the same thing, dropping in performance. I hit carb heat, and it improved immediately, and I went on my merry way.

The view looks amazing from up there 🎉😮😊

yes carb icing! Secondly at 10, 000ft you should have been full throttle already, you can only maintain 75% power up to about 8000ft, at 10, 000ft would give you approx 2650rpm and 69% power at 2500rpm you'd get 55% power. (standard day of course)

10, 000ft it’s cold up there..hot engine and moister and cold what do you think would happen!

i get it in mine a good bit. its pretty common in a 150

Those continental engines in 150's are prone to icing. Pull carb heat and watch rpm dip and come back but lower. Close carb heat if it happens again you either fly inefficiently by continuing flight with carb heat or lower your altitude.
