SIL GP200 Jetex 22mm SOI-100 carb with jets pilot 45, main 123, choke 50 NGK B78S Rayspeed Fresco exhaust
Starts fine & runs fine if over 1/4 or 1/8 throttle, below that runs like a sack of spanners. If it was a car I'd say is was "missing".
Screwing the airscrew in or out makes bugger all difference, unless I screw it all the way in or all the way out.
This was a problem last year but I had another toy to play with and so it's been sat for 6 months. Problem still here now I've come to use it.
Crap low revs running

Thanks yes should read B8 and yes Jetex are shite. Other than that not sure what to do. I have a better quality air filter on order I'll give that a go.
I get my kicks out on the floor.

Jetex when set up correctly are NOT crap !
Strip carb and clean pilot jet circuit. Fit 50 pilot.
Check that float is free to swivel.
If that don't fix it it may be electrical.
B7, B8, B9 won't make diddly squat difference to your posted symptoms.

Thanks Chris. I fitted a new CDI which helped last year when it was very difficult to start. I have a 48 pilot I could try that.
