It's not done yet, but getting close. Any feedback is appreciated.

Hello Tim,
Hats off to you for putting this in writing in a manner in which (in layman’s terms) ordinary folks can understand the workings of the Weber 48 IDA carburetor. Your writing has put my thoughts into black and white as a comprehensive piece. Very well done in my opinion and very much needed for people struggling.
I did however find (I think a typo) a needed correction. I’m not trying to be a critic:
"For the size 55 jet, the area is 0.238 mm2. The size 55 jet is therefore 21.4% larger than the
55 jet and will therefore flow 21.4% more fuel."
Shouldn’t that read 50 jet? Again I’m not criticizing at all, just a correction.
Also I know you are refining this wonderful piece. The (4) illustrations (towards the end) of the emulsion tubes and gas flow; could show the Main Jet against the body. It currently illustrates gas going up the Main Stack Well as opposed to flowing through the jet.
Lastly here is a photo on my Main Jet stack with fuel flow stains on my emulsion tubes, you can use the image if it helps any.
Best Regards,
Earl
