Photo which briggs is it?

does anyone know what model of briggs this one is??

The guy I got my fh's from threw this parts engine in for free.

Its missing the cylinder fin shield with its id plate, "not on blower housing"

The carb & gas tank are wrong for it too, I think it came off of a similar

vertical shaft engine?? not sure. It's got tank mounts on the blower housing.

The engine base & head are cast iron = older, late 40's early 50's??

Also the base has a gear driven twin gear style oil pump so more heavy duty

then a splash dipper. Coming off the points there is a metal shielded wire

bolted to the mag plate for a kill switch lead = heavy duty / Army?

it has an air vane governor & also a fly weight gear governor delete in the

block casting like my model I except without the plate & 2 screws

"no hole machined there" Two cylinder head fins are broken because

someone had the head bolts in wrong & also two flywheel fins are busted off,

someone tried wedging a screwdriver in between them to try & get the

reverse thread nut off the crank & buggered up big time. I always hydro-lock

the cylinder with oil down the spark plug hole & clamp the engine to the bench & use a

beaker bar, or find a block of wood to fit inside the cylinder if i don't have oil.

the valves & seats look great, no pits or rigges & the cylinder looks good too

no ring ridge. Connecting rod Is tight & has the rod cap seam diagonal instead of straight across

the piston however is a bit scuffed. I was thinking i could repair the broken fins with metal pins & j-b weld & just

use some type of putty or clay / play dough for a mold & wax paper so it

wont stick to it. Any thoughts /worth it??

it does look like an N but they just has splash oiling. it probably was modified for some special industrial purpose.

Some model N engines have the gear pump.

If I remember correctly, a model N can have a plunger type oil pump or a gear driven oil pump. They also have two types of governors. Air vane type and mechanical.

I just checked my Briggs book and it shows two types of oil pumps used. Plunger type and gear driven type.

I would definitely say it's an "N" series engine.

EDIT: I had one and you will need a small Flo Jet carby for it, but you can also get it going with the carby off a 5S engine.

I have pieces to an old science experiment that I haven't finished yet...

I was thinking that I might try grafting it to this engine. It would make a really
neat project & wouldn't require a carb or fuel tank.

"link is for some reason set at 2x speed" click video gear icon & select speed / normal if its messing up....


don't laugh now, something I want to mess around with

Actually, I have personally seen and tested one of those devices that Paul Pantone let a guy bring back with him. I even went to Indianapolis for a radio interview and demonstration. While the demo unit was running, the muffler was cold and I sat directly in front of it for well over an hour. I had the thing running on Sprite, soapy water, coffee, and even heating oil. My only explanation was that the "reactor" portion was acting like a miniature refinery, and breaking everything down to its basic components. BTW, do NOT get near it while running with your wallet. It will erase every magnetic strip on your credit cards, debit cards, and drivers license. Don't ask how I found out.

An ex friend bought one of the generator sets, and it runs/operates perfectly, but it was the only one that worked out of the box that were sold. BTW, I've seen some newer videos on the device and the design of the internal rod has been changed a bit.

That's AWESOME. Yah im into this sort of stuff. There is another inventor I am a big fan of,

Robert Krupa & his Firestorm spark-plug.

I was looking for an interview he gave but cant find it. But.... he said that he went through a 55 gallon drum of used spark-plugs & found that they all had one thing in common, the center electrodes would were out round... "Tesla coil???" so he thought "if it wants to do that, why not make it like that"
he did.. & had an investor from a spark-plug company come to test it. They wouldn't buy it. IT WOULD NEVER WERE OUT!!! They blew compressed air at it to see if the spark would flame out, It didn't & there was moisture in the air stream & it would ignite it. He could run engines on a 40-1 air fuel ratio!!

& then there's this guy

https://autoweek.com/article/car-new...-stroke-engine

I saw his article in popular science 2007

---------- Post added at 07:57:46 PM ---------- Previous post was at 07:12:21 PM ----------

I find it ironic that when you go to work on an 80+ year old engine
that the only thing "not" in dis repair are the magnets in the flywheel...
the catalyst for the reactions...

I had a dream when i was a kid, me & my cousins were messing around in a
garage, trying to get this model airplane engine to run. One of em fired it up
& I saw the air intake open up like a camera shutter, WHAP-

"fell out of my bed"

Years later i was trying to combine some of these ideas together but didn't get too far. Make an engine double acting like a steam engine to recycle the power stroke, pipe the exhaust back into the crankcase, push the piston from the backside & somehow & make the crankcase oil pump injected like 2-strokes & just have an exhaust port the piston skirt would uncover "2-stroke"

Also build a curved camera aperture iris to fit into the throttle air-horn for the throttle valve?? curved blades would swirl & mix the air, heck I-don't know? & have the cam do double duty PULL & push the valves. Ditch the valve springs. Especially in a v8! that's 16 or more springs soaking up the power.

Anyway I digress. It would be more a a success to just replicate a core concept/ Idea & build on that then to combine ideas & over complicate things.
