After all these years I've determined after reading this article I was wrong. I thought carbs we're sophisticated devices. Apparently not.
 

Basics of carburetor operation

 

The basic secret of carburetor function is that inside each carburetor 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 carburetor’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 carburetor, 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 on the job, which is why the bike will occasionally fire as the gnome tosses his lone bucketload down the intake. There has been some research into using tiny dwarfs in modern carburetors. The advantage is that unlike gnomes, dwarfs are miners and can often re-open a clogged passage.

Unfortunately, dwarfs have a natural fear of earthquakes as many a miner should. In recent tests, the engine vibrations caused the dwarfs to evacuate the Harley-Davidson test vehicle and made a beeline for the nearest BMW dealership. Sadly, BMWs are fuel injected and so the poor dwarfs met an unfortunate end in the rollers of a Bosch fuel pump.

Other carburetor problems can also occur. If the level of fuel in the float bowl rises too high, it will wipe out the Section 8 gnome housing in the lower parts of the carburetor. 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 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 carburetor 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 is how a carburetor works. You may wish to join us here next time for Electricity 101, or how your bike creates cold fusion, inside the stator, and why the government doesn’t want you to know about it.

Don't tell me you didn't know that gnomes live only in Bing carburetors.
In Tillotson's ones there are leprechauns.
In the Italians Dellorto two are enough, their names are Bernoulli and Venturi.

And on the subject, Amal spelled backwards is Lama, and as we all know Lamas have a tendency to hiss and spit on occasion. 


I’m going to have to post this elsewhere Barry , if I may?

My carb always had spiders to operate it hence the name Webber cos they like the down draft in the summer to keep them cool.😎

hi alan

i liked webbers but none for bikes


i am feeling a lot better today just weening off the fumes and it is also a mind thing
once my mind sences  the fumes it kicks into panic mode and makes me feel a little sick and gives me pains in my stomach
so keeping away from the garage and trying to relax and think positive

it does help

hopefully, we can get together soon

and hopefully, us old uns might even get to have a  weekend meet up

Webber was an excellent Aussie F1 driver.
The "Ausser" (Austrians) made him lose a championship of the way to favor the German Vettel.
The definitively unpleasant Brit Chris Horner is not without fault.

Returning to the subject of carburetors, on this part of the channel, they are called Weber with only one b.

It was only last week that I was explaining to the Good Lady Bill the difference between a Monobloc and a Concentric carby. Half way through she said that she was popping out to the Co-op for some paracetamol and I've not seen her since. If anyone runs into her please bring her home as I've got parts of both types stripped down on the kitchen table for her to take a look at.

Nick.

  today i rolled out my 1942 harley to check it over, charge the battery and try and start it


i ended up stripping the carb and giving it a good clean

the float bowl was full of jelly from the old petrol but luckily it was fairly easy to clean up and after remembering the procedure to start it  had it running for a while on fresh petrol


boy does that old petrol smell i had a shower and can still smell it



the 1921 indian carb was fine but i did blow out the 3/16" copper fuel lines

i wont bother to start the indian


keep safe

hi all


i think i may have to isolate away from my garage

the fumes from the old petrol yesterday ( see above) really played me up last night and today

  i have just been doing to much around chemicals the last few weeks and my body always tells me when it is to much

luckily it has not happened over the last 5 years or so but has kicked in now  and it will take a couple of days to settle down

looking forward now to getting my gall bladder removed in 2 weeks then hopefully we will be able to start thinking of m/home travel again
