Exhaust Valve Sticking

[Colonel]

And here we have another stuck
exhaust valve:



On the "other" website I caught
considerable shit from the AME's
there for my fetish for clean engines,
inside and out, and exhaust valve
guide and stem cleaning IAW Lyc
SB388C and SI1425A ...

But despite what AME's might tell
you, you don't need to pull the jug
when an exhaust valve sticks.  I
know they like to R&R the shit out
of everything (just ask Mike Busch)
but it takes about an hour of work,
depending upon the condition of your
exhaust, and zero bucks to fix it.

55 min to take apart and put together
again, and 5 min to unstick the valve.

But what would I know?  I just do this
all the time.

Great post!

Perhaps you could share your ideas as to proper leaning procedures (in lay man terms) for us to enlighten ourselves?

Ok.  First off, LOP is like fucking a supermodel.
Lots of people like to talk about it, but precious
few people are actually slipping the sausage
to Kate Upton.  This is LOP:

This is how you lean in the real world:

On the ground, lean for max RPM all the time -
right after start, and after landing.  I lean in
the rollout.  You figure out pretty quickly if
it wants an inch, inch and a half, etc.

If you must sit and wait and idle, do it at
1100-1200 RPM to reduce bottom spark
plug lead fouling, and exhaust valve
deposits.

I did not make this shit up, btw.  See
the Lyc Operator's PDF.

Now, in the air, any time I am straight
and level, the mixture is leaned, and
this is how:

Regardless of carbureted or fuel injected
or fixed-pitch prop or constant-speed prop ...

LEAN FOR MAX AIRSPEED

By defn that is best power which is 50
to 100F rich of peak, which is in the
ballpark.  A lot better than leaving the
mixture knob all the way in.

Yes, I know it's not LOP.  You can spend
thousands of dollars on GAMI injectors
with a payoff time of 20 years at 35 hours
per year, to get LOP.

See above comment about slipping the
sausage to Kate.

I should mention that in the descent,
the objective is to keep the engine warm,
so DO NOT ENRICH THE MIXTURE IN A
DESCENT.  Especially in a reduced-power
descent, lean that mother all the way out.
This is really really really important.

To summarize:

1) on the ground, lean for max RPM
2) level in the air lean for max airspeed
3) lean in descent

KISS, and I'm not talking about the
guy with the tongue.

PS:  God, I love this website.  On the
"other" website, if I posted this, I would
be "banned for life", again.  You're not
allowed to have a sense of humour, you're
not allowed to be funny or be entertaining,
the over-riding priority is to be politically
correct so that David Suzuki doesn't get
his panties in a bunch.  No one gets offended
and everyone gets a soccer participation
medal.  Barf.

PPS  I was bottle-fed.  That's my excuse.
