how exactly does the low speed needle fuel line pinch test work? and where do you pinch the fuel line, right under the inlet to the carb, an inch before that, does it matter?

it allows the engine to burn what ever fuel is left in the engine. After the engine has been idling and the lsn was to lean and you pinch the line there wont be any fuel left in the case to keep it running so it will die very fast without going through the lean stage (reving up a bit)
If it was to rich and you pinch the line, the engine will keep going and rev up a bit as it burns off the residual fuel and goes through the to lean stage.
If it is just right it should rev only very slightly for a couple seconds.
if it rev's for more then a couple seconds and higher rpm's = to rich
If die's off very quickly without increasing at all = to lean.
