Teddy da Bear62 107 #26 Posted July 9 The 633 has reached its new home! New owner was wondering if there was a part or 2 missing? It has K141 Kohler with tillotson downdraft carb. Instructions for changing oil include how much oil to add for air filter? Don't think there is a container for oil, for air filter. Can someone show me a clear photo of the end of a 633 w/tillotson carb?? Share this post Link to post Share on other sites
