I have the 3/4 hp single. I has a simple, poppet valve fuel mixer, compared to the more modern arrangement your motor has. The decal set offered on eBay is for this later model WW with the side decals for our motors thrown in. I don’t know of a start/oil instruction decal for our motors but there is a link below to the Stop – Slow – Start – Fast decal for yours.
