I have a 2-stroke Skyhawk 48CC engine with a C-32CNS66-EPA Carburetor on it I was taking apart the Carburetor to clean it and a little needle/pin came out, I believe where it came from is called the needle valve. The problem I have is I don't know which is way to put it back in, point up or point down. Any help is much appreciated
