Hello Max,
My goodness, that was a very early EE video, I almost didn't recognise him! Thank you for posting it up, I hadn't come across it even though I enjoy his channel.
Correct me if I'm wrong, but those fuel compensation tubes do nothing else other than provide atmospheric pressure to the float bowl? And they have no adjust-ability at all? I have not worked on a carby like this before, but they appear similar to AMAL Concentrics, from what I've found online.
I ran out of time today to take it apart again and have a look. The G2 looks to work in the same way, just flipped 180? I'll have a look in my book that covers early Victa carbies. And you're correct, there is another port exactly where you put the red arrow.
I hope to get into it tomorrow after work, but no promises there.
