Welbike carb needle number…

My well bike only wants to run on half or full throttle.
I’ve checked the needle height. Tried raising it it’s made a difference. I’m thinking it needs more fuel at lower throttle settings so is it the needle?
It’s currently got needle size 2. Any thoughts would be appreciated.

No2 is correct and it should be 59/64" long from the bottom of slide. Ron

Cheers Ron.
That what I have it set at.Perhaps I’m expecting to much. Only just rebuilt it after a Rebore. I’ll try to give it some use, bed it all in a bit……
