I did some trading and hauled home another engine. Still have another one to get but it was in a position where we couldn't get it out of a junk pile right now. He has to move a non running car first.

It appears this little 5 HP B/S has never been run. For some reason the carb/tank setup is gone, as well as the governor arm and linkage. The engine feels right, pulling the recoil and has great spark. No evidence of exhaust ever coming out of the port. In the oil plug holes it's completely dry.

Still, it's probably not worth buying the parts, but I will probably do it anyway. Then I can brag about having two NOS engines nobody wants around here---LOL!

I didn't google the numbers yet.

I'll take em both....lol

Looks like the mid 90s briggs 5hp I had on a go kart as a kid. Ran very nice. Always was a pain to start warm.

I love the old tecumseh engines but I hate to say I've all but given up on them.

Cool! They are still out there, still better than any predator.
It's have to wait til next time I went to the barn, but I think I have a good tank or 2 for those engines.
Not new, NOS, but good used. Don't remember if they (it? Thought I had 2) had carbs on them or not, been a while since I looked at them.
 
I'd have to put it back together too..providing parts aren't an arm and two legs.
New carbs seem easy enough to find, Bill, but no new tanks that I saw so far. I do have one, but it's still mounted on an I/C 5hp that I ran on my go kart for many years. The engine still ran well when I put it on a shelf 20 years ago. I'd rather leave that engine intact and assemble this one too.

The used assemblies I saw on ebay were at least one arm and one leg though. 90-110 bucks!

I'd do you a package deal on them both too---LOL! From what you remember on this B/S and what I found out on the NOS Tec HS40 is they are about the same age. The Tec looks to be produced in 1996.
I'm jealous Aaron---I didn't get my first go-kart until I was 25 years old---LOL! Still have my 3rd and final one hanging on the wall, also for about 20 years now.

Kind of fell into this one, Dodge. A friend came by to order 10 stickers. He saw the HH120 that is going to scrap laying outside. He told me to come get a "brand new" engine that looked like that laying in a junk pile at his shop. I was hoping for a bigger one but still couldn't turn it down. He's got a Honda horizontal crank engine for me to, still in a pressure washer too but can't get it out until a non-running car gets moved.
If you run across a fairly clean tank, let me know. I do have a good running predator too but that's another story.

Along the lines of NOS Briggs engines. I found a use for one of mine recently too. As it turns out I wound up with a swisher tow behind finish mower as part of the package deal with the intek engine I bought for a tractor I have. The swisher came to me with an 8hp Briggs that had the multi piece connecting rod option.
As it turns out I have a brand new 1982 vintage 8 hp Briggs in the shed that will go right onto that swisher mower..... I had to replace the foam air filter as it was totally disintegrated from old age .... Still haven't put gas or oil in it yet though.
Currently I have the mower on sawhorses and no place inside to store the machine, whole. So, I'm going to wait for spring to bolt the engine into it, as the engine can stay protected from the weather that way til I'm ready to use it.
 
On the subject of NOS Briggs engines I have a few.
One is a 3-1/2hp 92900 series push mower engine, it's that cool bronze color. Made in 1974. I have a perfect mower deck for it. I actually wouldn't mind finding a NOS or very nice sycamore or Kmart deck and handle from the same era for it. Maybe a snapper?

I also have a 80000 series 3hp horizontal. Heavy duty version with ball bearing in pto side.
I did swap the crank as the one that came with it is a weird external threaded one and shouldered, the last inch or so is cut down to ~1/2". Never fired since built in 1970.
I had what I thought was a low hour similar engine here but was missing a few things. So I pirated the crank out of it and just finished swapping it out as it is a straight crank with 3/4" diam and full keyway, internal threaded 5/16 fine. It miked out exactly the same as the weird crank that this engine came with on the rod journal. I did pull the bearing off the new crank and pressed it onto the replacement Crank. I did spray the crank journal and cam bearing surfaces with some spray white lube as I put it back together. And I pulled it over once reassembled and it does have a nice bright blue spark. I didn't put anything flammable in the carb or spark plug hole as I still didn't put any oil into it.

I also have an nos 8hp vertical from (I think) 1984. I have a 40" swisher tow behind that is recieving that one. That machine originally had an 8hp Briggs that has blown a rod for the 2nd time according to the PO.

I also have a 12hp I/C, 1988 electric start model. it just turned 7 hours on the mighty tach/hour meter on my new to me Bobcat commercial 32" walk behind mower. I put that one together late last mowing season. I wrote about that one here as I was putting it together. That one ain't leaving.

I also have a late 80s 4hp I/C push mower engine. I also have a purpose for that one. You guys see my wanted ad for a chute extension for a bobcat 21" push mower? I have 2 of them, one is getting this engine.

I also have 2 brand new never fired Tecumseh LAV35's. Real short crank, vertical pull start. Spec numbers 1 digit off from each other, one 1969 the other 1970. Factory replacement for the old toro Guardian/Whirlwind push mowers.

And 1 more. Tec HM80. Was set up for a minibike or go cart type throttle, I had to change that out to a different style for the tiller that I put that one onto. That tiller went to CL earlier today, no bites yet.

All of these except for the 4hp Briggs and the HM80 came from 1 guy. A retired rental yard mechanic who was cleaning out his garage prepping for a move South.
The 4hp came a year earlier from an auction that I went to.
And I had to drive down by Comiskey park (where the white Sox play their home games) for the HM80. As with the rental yard bunch, I found the HM80 on CL. And went after that one just for this tiller. He had started it one time just to hear it run and then stashed it under the bench, late 70s engine he bought new with a purpose for back then that didn't happen. I did wind up having to replace that nearly new carb, all the soaking in the world didn't work. I found an nos one on eBay that wasn't an arm and a leg.
I have maybe another 1/2 hour of run time on that one. Judging by how clean the cylinder is and the intake port is, and the paint barely being tarnished on it's muffler it can't possibly have more than an hour on it from new.
On the rental yard bunch, I went there hoping to buy 2 of those but got a "all or none" spiel when I got there.
