Tried searching and getting frustrated. My buddy and I are updating a Wr400 with a '07 Wr450 Carb tonight. I have searched for the throttle screw link that is supposed to connect to the Wr250 page for length to cut or part number. All I ever get in searching is BS links or others not wanting to help and say search for it(plenty of links). Can someone please send me the page to cut or part number we need to get this done by the end of the weekend, please?
