250-500cc Where is the idle adjustment screw?

This is driving me nuts. The manual shows a different carb with the idle screw just above the fuel line. I can’t seem to find it and the choke knob isn’t it either. Here’s some pics.

And once again the pics come out sideways when I post them

Is it on the other side ? It may not have one . 77 rm 250 was specced without one oem

If it's got one it's right behind the fuel hose where it has written "sae". You can see the carb body has a bulging cast on an angle up towards the slide (at the rear of the slide), that's where the screw lives.
The pics you've supplied have the fuel hose right over where the threaded hole for the speed screw is.

I moved that, coulda sworn it wasn’t there, I will check again thank you

That was it haha it has a nut locking it and hard to get to but thanks a lot!

God I feel dumb now hahahaha

Glad you got it sorted mate.
