missing mid-range! Can you help find it?

Hi all
after a year of on/off gentle fettling I took to the road on the GT250A a week ago. The machine idles fine but struggles under load..
..until the throttle is opened wide then it's off like a scalded cat. I imagine that's when the mains kick in. I had the carbs apart a while back
and gave them a fair clean but I'm wondering now abou the needle jet. I'm used to seeing a drilled 'emulsion tube' in this position
but this looks different. Position 11 here..

I have a cheap ultrasonic so might bung 'em in there for a bit..
