G'day everybody, lovely find maxwestern. I love old Scott Bonnar and Rover slashers. I presume that grill on the top of the Briggs denotes a cast iron bore.
Got the K Mart mower going after replacing leaking fuel tap , cleaning out float chamber and swapping faulty spark plug with a spare working one. Starts easily and runs beautiful.
Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
