Determine vintage BS model

Looks like a 5 HP to me....... There are 3 sets of numbers on that black air shroud.... Either on top or one the side that faces the tank..

Post those and we can tell you what year and way more info on that beast.....

Looks to me like a 60000 series Briggs build in the late 60’s or early 70’s. Horsepower 3.5 or 5. Not that old, I actually worked on one very similar last week mount on a rototiller.
 
Rivet's ... The main reason I myself didn't say a 60000 series is because the choke is a dead giveaway.... The 60000 chokes go sideways instead of up and down....

That bigger tank also tells a story.... If they haven;t been changed of course...........

Plus Tard Mon Ami ~!~!
 
You are right, but that carb and tank can be used on the 60000, 80000, and 90000 series engines. It was one way we used to increase hp on the 3.5 hp engines. That was before we would sand heads, punch jets, and restrict airhorns to increase power. Even built one of these. https://m.youtube.com/watch?v=AMsXKkIuaPg
 
Those numbers refer to a 3 1/2 hp vertical shaft engine which mine is clearly not. Obviously somebody has swapped covers.
