Forgot to enrich mixture for take off
Hallo
I got a question for all the engine experts out there:
Prior to take off I forgot to enrich the mixture on a Cessna 172 (Lycoming IO-360) by missing out the step in the before take off checklist.
I leaned to prevent plug fouling.
I thought I leaned enough, so the engine would stall when I increase power.
Obviously not:
The engine ran fine for about 5 Seconds, acceleration was o.k., then after 10-15 seconds the aircraft acceleration became less, engine running rough.
At that point I noticed my mistake, pushed the mixture all the way forward and continued.
Airfield elevation is 560' and temp was around 55°F.
Now my question:
I was angry at myself because of this error, otherwise didn't think much of it. Reading some other threads, I came to think:
Can this 10-15 seconds period of running leaned at take off power already damage an engine?
Right now I'm trying to develope a habbit pattern to check the important items prior take off additionally to using the Checklist.
Thanks!
