Sears and roebuck B&S help

[Jhoppe]

Hello all,

I have what looks like a briggs 3hp made for sears. It came off a rototiller and runs okay. I was wondering if I could get some details on it or a place to search it. I can seem to find the briggs serial for it. If it's worth it I would like to put it in a minibike for my boys, since it not gonna need to be super powerful for a 7 year old

Thanks!

You have one of the old cast iron flatheads! Those are very bulletproof and reliable engines, provided you take care of them.

The extra heft of the cast iron block and such will offset the 3 HP in a minibike, so that would be a good kids bike motor. I'd fabricate some guards so the engine doesn't get ruined if you lay down the bike.

I can break down the code, just not right now.

EDIT - Looks like it was built in 1950?? Not totally sure, the code systems may have changed since that particular engine was built and my manual that I'm referencing to was made.

Here's the model code breakdown as best as I know:
10 Cubic inch displacement (about 3-4 HP)
7 Basic Design Series
0 Horizontal Crankshaft
2 Sleeve Bearing, Flange Mounting, Splash lube (bearings are ordered worst to best in this order: DU non-flange mount plain bearing<Flange mount plain bearing<Flange mount sleeve bearing<Ball bearing)
5 Looks like a 5 at least. According to my manual, that means electric start, but I don't think that's correct, it's obviously got rope start.

Can we see some more pics of it?

I knew you'd be along JT lol thank you for the help. The model number on it is 500107025 but that is on the sears plate

I don't know what the 500 means, I think it's irrelevant, but IDK that much about the old cast iron flatties.

Anything about it you with like to see in particular? I'll be there tomorrow

You have a model 6. It is rated just under 2hp. I have one. Here is a manual. https://www.google.com/url?sa=t&sou...FjAAegQIAhAB&usg=AOvVaw3ied7CNhPqf9COuxqJo1Jk

I checked again. Looks to be a model 8.

It looks like you had a David Bradley sticker on the shroud. Google and check out the cool lawn tractors it could have come from. The 500 should be ignored it is a Sears code.

It does seem like a model 8, but I cant seem to figure out early v. late 8. I am not sure on the sticker because it is pretty degraded. It came off a tiller, but who knows what it started life out on.
