Vertebrobasilar insufficiency - A Hidden Risk of Depression

Staff FAST Song




♫ If someone has a stroke near you
♫ The F.A.S.T. song tells you what to do
♫ F-A-S-T FAST
♫ F-A-S-T FAST
♫ The letter F stands for face
♫ If one half droops, no time to waste
♫ The letter A means an arm that's weak
♫ The letter S means it's hard to speak
♫ The letter T means time for 9-1-1
♫ Call right away so help will come
♫ Learn the song to show you care
♫ And help end stroke each time you share
♫ Face Arm Speech Time FAST
♫ F-A-S-T FAST
♫ Oh Face Arm Speech Time FAST
♫ F-A-S-T FAST
♫ Face Arm Speech Time FAST
♫ F-A-S-T FAST, ahhhhhhhh♫

Spark Plug Troubleshooting




The next thing you want to do is pull the
spark plug out of it so I’m just going to
pull the wire off, push it aside. Put a socket
wrench on it nice and easy, spin it out and
have a look.
It’s quite clean, it’s got some blackness
to it but there’s no large deposits. Looking
at the insulator around the electrode in the
centre, that’s not cracked, that’s very
important. Inspect the insulator, here’s
the insulator on the outside. That’s the
electrode.
This sparkplug is a little bit blackened,
a little bit fouled, you would say. Now the
most likely cause of this is overfuelling
or a rich fuel condition. Reasons for a blackened
or carbon deposited spark plug would include
things like too rich a fuel mixture or a sticking
choke or a clogged air cleaner, you know,
anything that’s going to increase the fuel
in the fuel : air ratio. Also a good possibility
is oil seeping past the rings on the compression
piston and getting up into the combustion
chamber and fouling it.
I had the good sense to hold onto the literature
that came with the lawn mower when I bought
it ten years ago. See it says right here the
gap on the spark plug should be thirty-thou
so we’ll just check that with the feeler
gauges. It’s pretty much a perfect fit for
thirty-thou so there’s nothing wrong with
our gap. Clean it up with a nice soft wire
brush and reuse it.
Anyway, so there is no adjustment here. The
only adjustment I can make is I can bend this
metal tang, right here that the governor spring
is controlled by and that will speed up my
high end. This is the governor spring right
here and this metal tang here is its anchor
point. Stretch the spring further to speed
it up or compress the spring a tiny bit to
slow it down. In this case, I’m burning
a little too rich so I’m going to add a
tiny bit of speed to the top end. There we
go. I just bent it a tiny, tiny bit.
Here we go: I’m just going to put in my
spark-plug after giving it a quick check.
Now you definitely may want to change your
sparkplugs. They’re cheap and sometimes
if you have a no-start/no-run problem it could
be as simple as a dead plug. It’s such a
common problem that if you still have a no-start/no-run
problem: it’s not a bad idea to go get a
second new plug and make sure that the brand-new
new plug that you just tried isn’t also
dead.
[Mower starts]
OK now I’ve run the machine for an hour
after the tune up and â€" check it out. It’s
starting to whiten. OK, it’s obviously hotter
over on this side, you can see that. Spark
is hotter on that side but it’s starting
to whiten up which means something’s worked.
Either the tune-up or the raising of the operating
speed has leaned out the mixture enough that
we’re starting to get a nice clean burn.
