Oh boy -- test driving a new modem in my friend's computer just in
time for a disagreement...
Lean fuel mixtures burn hotter than rich ones. What do you do to
increase temperature of a welding torch? Increase the oxygen. What
happens when you put too much LP to your grill? The flame turns orange
(cool). You'll know when you have unburned fuel in the exhaust system
by the inevitable muffler fart or explosion, depending on amount (this
is what happens on loose engines that continue to rotate briefly after
ignition is turned off).
BTW: my cat melted when the fuel pickup was totally stopped up -- an
ultimate lean condition.
And yes, my firefighter friend just confirmed you can indeed put out a
fire with LIQUID gasoline (it's the oxygenated vapors that burn).

PS: After further conversation w/ fire department buddy, better example of
lean vs. rich fuel mixture would be soldering torch. Only variable w/
plumber's torch is propane (uses outside atmosphere for oxygen just
like a car). Welder's torch is a closed system.
Apologies...

Subject: Re: lock cylinder issues
The door lock cylinder is usually the first to go. A "quick and dirty"
fix is to switch the door lock cylinders from driver's door to
passenger door. If you have the older 2 key system just get some new 1
key system locks and upgrade (expensive). Another option could also be
a Lockzilla Remote. This way you don't have to use the key to unlock
the doors anymore unless the battery goes dead. In the meantime try to
use the key that is the least worn origional, copies are no good and
wear too fast. Go to a lock supply or an auto store and get some
graphite dust, it comes in a small squeeze tube. Spray some into the
lock and some on the key and work it in and out. That should help a
little but if you can put the key in and it doesn't go in straight the
insides of the lock are worn out. Lubricating ALL of the locks on the
car is a good idea at least once in a while. Don't forget the ignition
lock and the "vault" behind the driver's seat.

Subject: don steger's front kick speakers - need help
Hey all,
i recently purchased a pair of Don Steger's (delorean motor center) front
kick speakers but i can't figure out which way they go when you mount the
pod
(orientation). seems to me they could go a couple differernt ways but i'm
sure there's only one way intended. i would of course call Don up but
it's
the weekend and i wanted to install them now!!
if anyone has these and can send a really quick pic showing which way to
mount them, i would be very appreciative!
Thanks,
Andy

</SNIP>
You can put out a match by dumping a cup of gasoline, but what do you
think would happen if you tossed a cup of gasoline onto a cherry red
catalytic converter? (Don't try this at home kiddies:-)
What the firefighter explained, is exactly why the converter melts down.
The unburned gas is vaporized, oxygenated by the catalyst, burned, and
overheats the catalytic converter.
The "experts" agree that excessive unburned/raw fuel entering catalytic
converters is the primary cause of catalyst meltdown.

You're guessing. Fact is, RICH will burn up the cat. Try it. Put the
warm up regulator connection on the cold start valve and keep the
car runing for a while - and watch the cat glow. Dave knows what he
is talking about!

PS - I would be suspect that your cat was burned up BEFORE the lean
problem occurred.

I can cut a brand new key from code, too; to exact dimensions. The
problem,
though, is some cars do not have a code or the right code listed in the
driver's door above the headliner. The code will be five digit number
between 7,000 and 9,999.
This is for anyone interested, email me offlist dmc4687(at)mindspring.com.
If you don't have that number, then we are out of luck. I can try to
decode
from a worn key, but that MAY get expensive shipping blanks back and forth
until we get it right. For $20 I will send you two keys (US destinations).
They are not rubber head replicas, though I have considered buying some
for
this purpose (if in stock). That would add like $16 per replica cut.
