Will check that out Mattax- thanks!
Do indeed enjoy the “ think tank” type work - good for the grey matter .

Talked to the Local carb tuner and- have a better grasp now as he stated similar to Brad.
The math is the math.
The problem he stated ( if I got it this time ) is that we are often dealing with less than precision instruments ( carbs) which carb tunes try to rectify and then all the variables of fuels/ air quality etc.

Thus some see this area as “ magic “ while those dealing with the science are dealing with math and- headaches- grin.

He also stated- Carbs are funny things because they go on engines and engines are funny thing because people build them- we don’t get cookie cutter constants and that’s why we get to make a living .

That’s pretty close- best I remember anyway .

He just had one for a 1600 hp , well built engine and carb just “ wouldn’t work “ after everyone tried all they could- sent it to him.

Couldn’t find a thing wrong ,,, until he noticed the scratch “ pattern “ on baseplate.
Checked it for flat- sure enough, wasn’t .
He dyed it and measured- someone had taken a sanding belt to it!
12 thou milled off later- great carb!

Magic?
Nope .

Math and attention to detail?
Yep.


Btw- am I The last guy on here to see “ Thumper carbs “ on Facebook ?

Sheesh - sweet .
Take me another few days to study that page - some really nice pieces there.
