I bought a SB sticker off ebay, the seller saw the post on here and sent through some information dating the mower to the 60's. And he also included a copy of a handbook with operating instructions and spare parts diagrams.
I just thought he deserved a huge thank you for going the extra mile or two.
Witht his info We are now thinking 75 cc, and i keep searching the net for one with an identical fuel tank, unless of course the old one rusted out and was replaced with this round item as this is the only real difference from the diagrams, and maybe the pull starter.
