Hi everybody!
Vizsla, I would never attempt a flight if something doesn't feel right

My curiosity was more academic of the kind, would the engine deliver enough power for a somewhat normal take-off. At our field, my only option would have been the highway in case of an emergency right after takeoff. That or the town's main street
@ fernytickles & cjboy: That's the creepy thing: although vibrating more than normal, the engine did rev up without hesitation.
I flew that airplane the weekend earlier on a long x-c at 8500ft, leaned it out but always reajusted when I changed altitude. It was then flown twice by students, one of them on his solo x-c.
And I too believe that this isn't due to a one-time misadjustment. If I'm pragmatic, thinking of what 152s are put through generally as student aircraft, they must be pretty sturdy and forgive lots of beginner errors.
Again, I'm still pretty "green behind the ears" myself

, but eager to know what to look for in cases like this in the future.
Cheers,
Alex
