I'm hoping someone can help me ID the year and model of this Lawn-Boy mower that was passed down to me. My grandparents bought this mower new sometime in the early to mid '60's. It is a beige-colored bricktop with blue trim, 18" cut. It runs good, but is leaking fuel from the float bowl/fuel shut-off valve. I would like to repair and mildly restore this mower. Thanks for any help that anyone can provide.
