I bought a carburetor kit with a new needle and seat for a Marvel-Schebler TSX-470. The seat would only thread on about a half a turn and then tighten up so much to where it was becoming destroyed, the old one threaded on easily. The thread dimensions were correct but the thread length was .008" too long. If you run into this take a fine file and gently file down the length of the threads. It threaded on easily after that. Don't force it or you'll run into big trouble. The Quality of these kit's are getting worse and worse.
