I put a new carb on 110 kids quad it is leaking from overflow even when quad off but quad runs and idkes better than ever signed lost ?if anyone has any ideas I would appreciate thanks.

 

You need to go into any new carb just to check out float height,making sure jets are tight etc.No telling how long they've sit before they were sold.Hopefully the float needle is just sticking a bit and a little cleanup and adjusting will fix it.
