Engine failure

The newer 172's are fuel injected. They will have an engine driven fuel
pump and and electric one.

Some are. So I have to ask.



Without me having to go to the TCs and do a search, can somebody please tell
me what series of 172s were injected?



Anyhow, if so it may be linked to a problem in the fuel pump.



And again the models of 172s that have fuel pumps?

A lot of 0-300's in the older 172's have fuel pumps, I am not too sure why
though. Maybe because of the 6 cylinders?

I have had an engine quit multiple times in my twin on roll out after
pulling the power back to idle. It ended up being an idle mixture
adjustment, not carb ice (fuel injected). The other possibility was sloppy
linkage in the throttle, but this was tight, and testing the fuel pressure
showed it to be too low at idle.

Don't assume it has to be carb ice.

I had a situation yesterday at the end of my local "just because" flight
(you know, one of those where you really have no place to go but the
weather is favourable and you just want to go flying).

Was flying a rental 172. Took off like a rocket (lightly loaded solo...
cold air about freezing), tooled around practicing stalls, steep turns,
etc. Headed back to the pattern and did a couple of touch and goes. On my
final landing, I declared a full stop, and decided I would practice a
short field landing. I cleared the "imaginary" 50 ft. obstacle, dropped
the last notch of flaps and cut power... and the engine quit. No issues,
because I had the runway made (I didn't even realize that the engine had
quit until rolling on the runway... I knew something sounded different,
but the prop was still windmilling and I was concentrating on the flare).

I rolled out and the prop stopped, and I called traffic (uncontrolled
airport) to let them know I was a sitting duck. Checked the primer
(locked), mixture (full rich), fuel selector (both... and lots of fuel...
I filled up with only just over an hour of flight since), and restarted
with no problems and taxied off the runway.

Though it turned out to be no danger, I couldn't help but feel a little
disconcerted. A low level power off descent away from the airport could
have had a more serious outcome, or what if I misjudged and didn't have
the runway made when I cut power?

I taxied to the maintenance hanger (after being directed there by the FBO
via radio notification of the situation), and explained what happened to
the maintenance guy. He said that there is a stop on the throttle to keep
the idle setting from being too low that probably needed adjustment. Even
so, during shutdown (after restarting), idle setting on the throttle was
still 800 - 900 RPM, which should be enough to keep the engine running I
would think.

Anyone else experienced this and can share their thoughts? I'm about a 60
hour pilot, so not much experience.
