I just bought a new float needle that fits and it still seem like the tang is not even touching the needle when I press the floater all way in.I have a PJ carb,maybe the floaters are to a pwk carb,maybe not the right size.Can anyone help me out here gas shoots straight out the overflow hose when I cut the fuel on
Replace the float as well. Sometimes depending upon what material it's made the float can be somewhat soaked with fuel changing the weight of it.
Needle and seat issue
Your needle isn't hitting the seat in the float.
check for physical obstruction of the floats
always replace the needle and seat as a pair. They fit together.
ensure your floats actually float and do not have any holes in them
If you provide more information like the model of the bike we can provide a less generic answer perhaps. Please include model number of the carb as well as information about the needle you purchased.
