The basic secret of carb function is that inside each carb are
thousands of tiny gnomes; each with a small bucket. As you open the
throttle, more of these gnomes are allowed out of their house and into
the float bowl, where they fill the buckets and climb up the carb's
passages to the intake, where they empty their buckets into the air
stream.

But, if you don't ride the bike for a while, bad things can happen.
Tiny bats take up residence in the chambers of the carb, and before
long the passages are plugged up with guano. This creates a gnome
traffic jam, and so not enough bucketfuls of fuel can get to the
engine. If it gets bad enough, the gnomes simply give up and go take
a nap. The engine won't run at all at this point. Sometimes you'll
have a single dedicated gnome still on the job, which is why the bike
will occasionally fire as the gnome tosses his lone bucket load down
the intake.

There has been some research into using tiny dwarves in modern carbs.
The advantage is that unlike gnomes, dwarves are miners and can often
re-open a clogged passage. Unfortunately, dwarves have a natural fear
of earthquakes, as any miner should. In recent tests, the engine
vibrations caused the dwarves to evacuate the Harley Davidson test
vehicle and make a beeline for the nearest BMW dealership. Sadly,
BMW's are fuel injected and so the poor dwarves met an unfortunate end
in the rollers of a Bosch fuel pump.

Other carb problems can also occur. If the level of fuel in the float
bowl rises too high, it will wipe out the poorer gnome housing in
the lower parts of the carb. The more affluent gnomes build their
homes in the diaphragm chamber, and so are unaffected. This is why
the bike is said to be "running rich".

If the fuel bowl level drops, then the gnomes have to walk farther to
get a bucketful of fuel. This means less fuel gets to the engine.
Because the gnomes get quite a workout from this additional distance,
this condition is known as "running lean".

The use of the device known only as the 'choke' has finally been
banned by PETG (People for the Ethical Treatment of Gnomes) and
replaced by a new carb circuit that simply allows more gnomes to carry
fuel at once when the engine needs to start or warm up. In the
interests of decorum, I prefer not to explain how the 'choke'
operated. You would rather not know anyway.

So, that's how a carburettor works. You may wish to join us here next
week for basics of electricity, or "How your bike creates cold fusion
inside the stator, and why the government doesn't want you to know
about it."

i eagerly await the cold fusion/government conspiracy episode as I feel the public needs to know the truth.

And whatever you do don't get on the wrong side of these gnomes. Because they WILL p1ss in your carby and stuff everything and then blame it on water in your fuel.

So what about EFI?
Is this run by gnomes that are computer savvy?

[4stroker]

yeah its run by geek gnomes!

Makes you think twice about using the choke lol

What happens to them when you add octane booster to the tank ??
