Geh. Found it, thanks hammon
It was indeed below the sticker that says "do not overfill the oil," right in the stripe of rust.
Managed to eek out 302431-0144-01-7401101, and that number thrown into the Briggs website
does pull something that looks like mine - an old-looking horizontal 10hp Briggs I/C
I'm pretty sure it is a 10, the 16hp in my 7116 is quite a bit bigger than this guy.
Not positive on those numbers, as that rust spot does make it interesting, but I think I've got it. Cheers
Edit: Huh. Threw the number into google and I find that atleast the engine is from a 3414. http://www.smallenginewarehouse.com/...ity&Model=3414
The 3410's number is different, Briggs 243431. Same manual for it though, seems it covers the 10 and 16hp versions, with the 14hp sharpie'd in on the cover
I just gained an extra 4 horses, cool.
