Can anyone tell me what RPM an O-470L is supposed to idle at (assume sea level, standard 15C 29.92" day)?
Mine idles at about 500 RPM and the engine has quit 3x during landing rollout. It starts sputtering as airspeed decreases after touchdown, and when power is added to turn off the runway, the engine dies. I've grounded the airplane until the problem can be fixed, and am hoping adjusting the idle to 600-650 rpm might fix it.
For some reason, it runs OK at idle during the runup, even with carb heat on, but after the engine has run for a bit (and heated up?), it tends to sputter and die like this after landing. It has happened with both carb heat on and carb heat off, with outside temps ranging from 5F to 35F. Mixture is always rich and prop forward for landing. It's a C182B with an 82" McCauley 2 blade propeller.
We are trying to rule things out before looking at the carburetor but this is the first step. Carb and engine was overhauled 10 years and 500 hours ago with the rest of the motor. The mags just got their 500 hour insepctions/refresh.
Thanks!
