This is my grandpas old Western Auto push mower with a Briggs And Stratton 2 1/2 HP exellent runnig engine.He says he bought it in the early 1950s and has used it ever since.It starts on the first tug with no smoke,knocks, and is quiet as a mouse.I use it and the neibors love it and it does an awesome job! The only maintenance he's done was oil every 10 years about and two air filters and sharpening the blade. Awesome mower with an awesome engine. In the background is the new craftsman with a Briggs, no choke or prime just one pull, so easy a caveman could use it.
