Float bowl

Recently picked up a ktm 125 to tidy up a trade on.
Ive pulled the carb off, stripped it and put it through the ultrasonic tank.

Inside the carb bowl there is a long needle, which I believe is connected to the drain off screw/overflow

The needle snapped during cleaning and is barely hanging on. Some of the replacement bowls I've seen do not have the needle fitted?

I think it acts as a overflow level for the bowl? Could I run it without as long as the float height/fuel tang is set correctly?
Any thoughts?



Is it needed?

Isn't it connected to the carb overflow pipe so if it's not there won't it continually run?

Yes it's on the overflow pipe on base of carb.

Now I've thought about it, if it's acting as a overflow fuel height then as you say it will just run out constantly.

I was thinking the overflow screw on the side of the carb would keep it close. But this can't be the case as you still get fuel leaking with this shut
