removed needle from slide in carb after i but it back together it has a little play up and down 1/6 of an inch is it normal or it has to be tight

 

If needle assembly is in order, the grey plunger with small spring
holds everything in place. There should be movement up and down,
you should feel light pressure and the needle should return upon release.
If needle is in the 4th or 5th groove from top of needle, there is only a small movement.
