| Subject: | Mag Timing/Fouled Plugs... that sort of thing |
Okay... now that the fly off is complete and the first couple of oil
changes are behind me it seems I need a crash course in keeping N410CF
finely tuned. Over the last few flights the engine has been
progressively more difficult to start. I've been experimenting with
different starting techniques and was attributing the problems to that.
The last trip out to the run up area it died at idle. I restarted, ran
the engine up to 1700 rpm and leaned it out. The subsequent idle check
was okay, but things aren't feeling quite right.
I'm running a stock Vans supplied YIO-540-D4A5 with dual slick mags and
a slick start... Total time on the engine is 44 hours
I've not yet purchased a plug cleaning kit or a mag timing light and
would love some input on what I should buy.

Buy a buzz box, and a mag timing pin (you may not need that for a while).
Then definitely check your ground lean setting on your engine.
While idling, go mixture full rich, check the RPM. Lean it out
until it starts to die. It should raise in RPM before it dies.
See how much higher it goes than what you started at full rich.
You want 20 to 50 RPM rise, no more no less. The star wheel
on your throttle linkage arm is how you adjust it. Once you get
it close a couple clicks do make a difference so maybe start with
a few clicks but eventually you'll be down to ticking it one
or two.
If you use good starting technique both cold and hot starts
should be pretty easy. And if you screw up a hot start you
can always slightly flood it and then use the flooded start
procedure and get it going fairly easily.

Also=2C leaning during taxis and warm-up will help
Keep the plugs clean.

Jeff, are using a retard mag, or an impulse coupling? If the timing slips
on the retard points it'll get hard to start for sure. Check the retard
points just like the mains, but they should opening at or just after 0*.

It sounds like the engine has never been timed? Apparently (?) Lycoming expects
the installer to check and adjust the timing. Several builders, including myself,
have reported the mag timing was off, right out of the box.
I bought a "kit" buzz box (some soldering required) for less than $50, works fine.
I can't remember where I bought the kit, sorry.

A mag timing box is not that expensive.
http://www.aircraftspruce.com/pages/to/enginetools/synchronizer.php
I don't with the small Slicks, but with the large Bendix S1200s that I
have, it is necessary to remove a mag to install the engine to the
engine mount. Obviously the mag has to be re-timed after re-installing.

I assume you meant to say "I don't know with he small Slicks...", but they do not
have to be removed to hang the engine.

Retard mag... and the mags were timed with the help of a couple of A&P's
with a buzz box before the first engine start. It seems to me that the
retard points and main points of the retard mag move together... so if
one is off time the other would be as well. Am I missing something here?

You are correct. Is there a way to test the Slickstart box? I assume
your mags are set to 25 degrees.
There are various methods to cleaning plugs. I prefer a dental pick to
remove lead balls, and rotating bottom plugs to top to keep them clean.
I'm an hour or two behind you on TT. I have one plug that seems
intermittent, but it tests okay as far as resistance and isn't fouled.
While my ignition is a pair of Bendix S-1200 mags I find fuel system is
most temperamental on starts. The engine wants to be rich on cold start,
and have found putting mixture full rich just before cranking gives a
quick start. Hot starts are another mystery. Boost pump on, mixture idle
cutoff until starting to crank seems to work, adding mixture slowly
while cranking. If not enough fuel when it fires it quits easily.

No, that's correct, when you twist the mag relative to the engine it moves
both sets of points together. It's probably worth checking even though
they were set not too long ago.
But--the retard and the main points can be timed individually as well,
relative to each other. As the points wear, their timing changes--probably
close to equally but not necessarily. So it is possible to have the mains
firing right at (25*?) and the retards firing at, and say, 10*
after instead of 0. You can check that with a buzz box but to fix it the
mag would most likely need to come off.
