1968 Briggs and Stratton 2hp horizontal shaft flat L head engine - complete rebuild - restoration 

Wow, that was awesome! I love how you just did the basics and left it in its original state. I never thought that thing would run again after having all that water contamination inside, just goes to show you how durable and great those old flat-heads were. Things don’t need to be right on spec, as long as they’re close it’ll run just fine. We used to rebuild these in power mechanics class back in high school, now they don’t offer shop classes anymore. A lot of mechanically clueless people out there anymore!

I enjoyed seeing a no-frills rebuild, using the tools, methods, and materials at hand. Nice job.

Some people will never understand the feelings of something starting again

Thank You for this no nonse approach to a complete rebuild and repair of this little workhorse.

Extremely helpful . Great editing . Straight and to the point. Only wish the job could actually be done in under 30 minutes. Thanks for sharing

Fantastic video !!! My son in law gave me a project a Briggs and Stratton lawn mower to overhaul Your video will be a grate help

I rebuilt a Tecumseh 3HP horizonal shaft engine that pretty much looked like that B&S 2HP. Nice to hear them fire up after you take the time to fix whatever was wrong with them. Thumbs Up!

Thank you for posting this! I’m rebuilding a ‘67 right now and didn’t know how to get the valve springs back in without buying the $35 tool. Great trick with the wrench!

Thanks. I needed that. I'm almost done with the removal. Need to order parts, and rebuild.

Bro made a homemade ring composer good vid

Your Mom had to love you washing parts in her sink... I really like your dish washing gloves... Cool old engine..

I love seeing these flathead engines getting heavily modified

That little hole in the top of the starter clutch is an oil hole. It should have a little piece of felt in it to soak up oil. You should oil it there.

That’s a great video. I’m about to start rebuilding one myself

Video was so good ive watched it 3 times . Good job ! Thank you . Maybe because I have the same engine made in 1987 .

Great job! I've finished one week ago to rebuild one from "97...I believe is quantum 50 from Briggs and Stratton...for a lawnmower...it was negligent for the last 10-15 years...and installed on a 2012 Husqvarna LC 48 EV....the 675 series from 2012 it was damaged (and to expensive to rebuild).... It's running perfectly, and I only clean it and replace al the gaskets....( And the flywheel from 675 because I've wanted to start it with the starter)

Thanks a lot for uploading this content. I bought a clapped out garden tiller from the 60's for ten dollars hoping that at least the gearbox worked. Now I think I may be able to get the engine running, too.

Great video, thanks for sharing!

Love it man!! Good stuff!!

awesome job. i got a 5hp im going to buy soon and this is the motivation that i needed.

Need to use the box end of the wrench, also should have put oil in the pull cord starter instead of wd-40 and grease the ball bearings on the starter cord assembly.....

I thoroughly enjoyed this video. However, there's no way I would have gone through all that trouble without painting it.

First lawnmower I built from a box of parts had the horizontal version circa 1960. Rebuilt the motor when I was about 8-9 with my dad but did lap the valves too. Didn't see you do that. Liked that you left some of the patina but would have cleaned up the carb rods and springs. OA pretty good rebuild of rugged old beast and parts still available.

I love to restore old engines !

You are a magician. Awesome work on that restoration. God{Bible] Bless.

Good content. Thanks

Hola haces un trabajo d relojeros, con materiales d desecho, 🙂 bravo x ti,,

the hole atop the starter clutch is where oil can be dribbled down. there is a pad that holds the oil underneath the hole. use engine oil not wd40 or similar

This was really fascinating to watch. You earned yourself a new subscriber

Just saw your video...Few pointers if you don't mind... Missing a ball inside the pull cord hub assembly, and always put a bit of lube (lithium grease) in the crankshaft end before installing the hub assembly, should have checked the ring gaps before assembly, may require .005 oversize rings (chrome) if the cylinder is worn out, especially this is a used engine plus you honed the cylinder, might be a good idea to torque the con-rod to factory specs, how a bout hand lapping the valves before assembly, recoil assembly spring has a large "S" bend in it, doesn't seem normal, when I saw you put a new pull cord and just tie a knot, I knew that at one point it would undo itself because that happened to me before (tie your knot and use a pair 2 pair of pliers and pull the knot from the top and hold the bottom)

I had this same exact engine

You did a very good job I'd have to say you have more balls than I do but for future reference...heat whatever metal is surrounding whatever you're trying to get out like a bowl or whatever expand that metal not what you're trying to get out make the muffler pipe & so on It works for me

Thanks. Nice .

I have that exact same POS Chinese ultrasonic cleaner! Works great for pistol cleaning!

thank you

You may use the classic word "PERKELE"? Regards Stig Österberg from Dalsbruk in Finland.

While the rebuild is nice, one thing I would suggest is that instead of hammering something directly, you put a block between the hammer and the object as to avoid percussive damage.

Mam taki sam silnik tylko 3.5 km do pompy wodnej

Back at a time when camshafts weren’t mostly plastic 👍

I understand the value of keeping it original. I have this exact engine and am in the same process of cleaning it up. But id like to modify mine with an aftermarket carburator. Do you know how id determine the size ?

I’m working on the same engine. This video is insanely helpful, thank you! Noob question: is the thread on the muffler a standard ‘righty tighty lefty loosey’ thread? I’m having the same stuck issues as you but I wanna make sure I’m not making my problem worse!

What was the cost on the rebuild? By the way great video thank you for showing the process 👍

Nut in pulling rope ie. Knot it's a double nut put role in to knot twin .

Nice post! I'm working on the same engine. Mine is a 1976. Did you notice that the valve springs are different in height? I believe the taller is the exhaust. Is that also what you saw?

Will this motor work for a mini bike

Nice. Watch and learn. What was the cleaner? Simply Green ?

Thanks for this video, greatly helps. I have a similar engine that I am trying to rebuild that's off a 1967 Tiller. Both intake and exhaust valves are seized up so I was taking the crankcase cover off to fully remove everything, clean things up and rebuild, replacing whatever needs replacing. The only difference I see with my build vs what you are showing. At your 6:07 minute mark, once I pulled the cover I have a bearing flush with the crankcase gear/timing. Any idea how to pull that bearing off?

I am rebuilding one of these atm The flywheel has a woodruff key, like the one in the video. The points cover says "Caution Do not use a steel key. See Instructions" as doe the cover in the video The key that came out looks to be steel. What am I supposed to use? Is there some other kind of key than steel? Thanks to anybody who can shed some light.

Gostei da recuperação do motor, mas poderia ter feito o embelezamento do exterior com uma nova pintura. 👍🏻

That kink in the recoil starter spring should most definitely have been straightened (not at all hard to do) and may cause easily avoided problems in the future.

Tôi cũng có một máy như vậy nhưng là 5hp và tôi đã làm cho nó hoạt động tốt

I can’t figure out who the original equipment manufacturer was. I can read Clipper but it can’t be a Cooper Clipper because they were based out of Marshalltown Iowa and it would be orange not white. Anybody know who made the equipment this Briggs was on?

Where did you buy all those gaskets and other parts like the muffler buddy

Pretty good. He didn't have a few of the tools that he needed though.

The rings that went in are for a Iron bore engine. You need chrome faced rings for the aluminum bore. The bore is going to wear out fast.

Bravo👍👍💟👏

Why did you not lap the valves

Mod N weren't they when they had the float carb. We used to hotrod them where were 12 years old and put them on go carts we made with 2x4s, an old reel type mower (Even old in 1958 ) and race them. Real trick with the rope steering and no brakes, but we learned enough to end up in 600 HP A/P Corvettes 10 years later. Too bad there are no more engines like that for kids to abandon their smart phones for today. You can learn a lot more from an old Clinton Motor then you ever learn from playing Pac Man. And Hey, all that work and no paint. Krylon works wounders,,,,,,if you don't go for Chevy orange.

And the start cord come righ out and wips in face.

I know you said you liked how it was but I would have repainted it not really a restore but still a great video

👏👍

But great job

please get yourself a torque wrench. other than that. excellent video :-) is this a 60102 2hp engine ? if so i have the same 🙂

The Previous owner ! Just RAN ! THIS ! ON ! WATER !! VAPOUR !!

Why didn't you show us how you recut the valve seats? Or did you blow that step off?

So, what did you put it on?

uh you forgot to add grease to that pull starter.

Can you please help me out with a model number on this??

No boot on that sparkplug wire is a shocking omission.

It's interesting you were able to find the parts, I had a hard time finding the parts for a 12.5 horsepower B&S. When I had a shop find the parts, it was cheaper to buy a new engine than the replacement parts. That is an excellent job Sir. Did you replace the piston with a standard size, or over size? With mine the cylinder was worn so bad, it would need a .020 over. Very expensive.

We usually just replace it with electronic and don’t even fool with the points

Should have put a smidge of grease for the slider on the pull rope area

I’d recommend investing into a torque wrench. Cringed at the con rod and head installation.

Your mom is gonna spank you good for using the kitchen sink to clean parts. I used my mom's 12-quart stock pot to boil the block & other aluminum parts clean.

Wd4 in the honer 😂😂 never sen that

Put some wd 40 on pissnit is

Valve clearances (lash) should have been measured before installing springs in case they need adjustment (filing).

Not really the best to do all the cleaning in the sink. Here they water treatment plants can track the oils and give you huge fines

THAT ENGINE IS IN BAD SHAPE..

Thanks for the video you should have painted it also

not a complete restoration unless you repaint everything

Don't you believe in paint

I’ve seen too many faults in there you’re in too much of a hurry to get it back together again you could’ve done part two of it

No t quedo pintura para la carcasa, " lo has desmerecido "
