Default Carb basics -- don't believe your mechanic

I hope it is OK to post this here. If not, please move it to the proper area.

The basic principle of carburettor 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 taken out of their leisure
areas 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 start your cart and run the motor for a while,
bad things can happen. Tiny bats take up residence in the chambers of
the carb, and before long the passages are clogged up with guano.
This makes it very narrow and slippery for the gnomes and creates a
gnomes traffic jam, meaning not enough bucketfuls of fuel can get to
the engine. If it gets bad enough, the gnomes simply give up and go
home to wash the shish off their shoes . 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.


Other carb problems can also occur . If the cart enrichener tube
rubber seal perishes , or the level of fuel in the float bowl rises
too high, it will flood the worker gnome's sleeping quarters in the
lower parts of the carb and worker gnomes may be unavailable for
duty while they clean up the mess . The more affluent Foremen
gnomes who build their homes above the carb slide are not affected by
the floods , and so have to roll up their sleeves and ferry the
buckets of fuel themselves . This is why the motor is said to
be "running rich".


If the float chamber fuel level drops, then the gnomes have to walk
further 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".


Please note that the use of the device formerly known as " the
choke " has finally been banned by the miltant groups GAS ( Gnomes
Against Suffering ) and PETROL ( Pixies Enhancing The Role Of
Littlefolk ) and replaced by an additional fuel passage 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.


There has also been some research into using tiny dwarves instead of
gnomes in modern carbs. The advantage is that unlike gnomes, dwarves
are miners and can often re-open passages formerly clogged with
guano . But unfortunately, dwarves have a natural fear of
earthquakes, as any miner should, and in recent tests, engine
vibrations caused the dwarves to evacuate the EZGO test vehicle and
make a beeline for the nearest Yamaha dealership. Sadly however ,
some carts employ fuel injection ( more correctly termed " Few Elf
Injection " ) and so the jobless migrating dwarves met an unfortunate
end in the lobes of a Bosch fuel pump.


So, that's how a carburettor works. Any Questions ?

Guess I'll be removing all carbs from our online store now. We'll never sell another after that

Do the gnomes have medical insurance in case of a backfire?
