I love those old Briggs engines. Definitely worthy of repair. Great video.
Me too, thanks James :)
Nice save Tom - amazing how tough those little engines are 👍👍
Thanks Claus! Great to hear from you mate :)
Thank God, I'm not the only one to use the kitchen sink! Great video.
Haha we’re terrible 🤣 glad the mrs didn’t catch me !!
I have an old Briggs and Stratton from 1983 when I got married. I believe it's a 2 hp. It was a wedding present from my parents. lol My Dad had a weird sense of humor. The other thing I got was a hand truck he paid $29 for and it's still going good. He left the price tag on it when he gave it to me. The edger made it for 30 years but it finally broke and I kept the engine. It's sitting in my garage and I want someone who could use that workhorse. It is so reliable. Great video.
That’s awesome, what an amazing testament to the quality of these older machines. The new ones are terrible in comparison - glad we can still get the old ones and parts for them too!!
There is something so satisfying about watching ghis type of stuff. I love it! Thank you!
You’re very welcome!!
Excellent job Tom, it sounds really good now. 👍
Thank you John! You’re always so kind.
Anytime brother
I really enjoyed this video. I wish more things could be saved in this disposable society. Your narration and way of explaining what you are doing is very instructive and you have good judgment on editing and making your videos long enough to teach and short enough that I can pay attention long enough to learn.Thank you for taking the time to make the videos that you do.
I got hooked on your channel by watching the Mighty Vac videos. I consider myself a tinkerer more than a mechanic and that is why I like your videos. I like how you help us understand concepts that apply to many more engines than what you are working on at the time.
When I was 16 I started learning by working on my cars, a 1975 Beetle and then a 1979 Porsche 924, (this was 1986-88 era, before the internet, it was book learning for me back then!) and then my parent's cars of various makes.
Later, when I had kids, I taught my boys to work on their own dirt bikes and four-wheelers. Both my sons are mechanically inclined and can work on engines, cars, etc. It makes me proud to pass that on.
My dad passed before I could learn to wrench from him. He had race cars, boats, RC planes and a real airplane, a Cessna. He worked on all of that.
My point of bringing that up is like me, not all kids get to learn from dad. Channels like this help another generation learn to tinker, wrench, troubleshoot, and fix things. And, I don't expect to ever stop learning myself. So thank you, sir.
Thanks for the kind words about my channel, I’m glad you enjoy it! Thanks for sharing too, that’s awesome :)
Wow! What a thoughtful comment. Your boys are lucky to have a Dad like you. Cheers!
Great job tom 👏 love to see a old briggs back to life look forward to the next video tom 👍
Thanks Mark! Glad you enjoyed it!!
Nice rebuild and restore. 👍
Thank you :)
A well completed project is the living testament to the quality, skill and workmanship of the craftsman.
Great video, and a great job bringing this engine back to life.
Thank you!!
Excellent camera work and presentation of the detailed steps of the repair. You do great work Tom.
Thank you! :)
Really great video Tom, you saved another one!! 👍👍
Thank you!!
Great save Tom. Looks and sounds a beaut
Thanks Al :) much appreciated!
That's pretty much a new motor now. Nice rebuild.
Cutting in the rain, that's devotion!
🤣🤣 yeah it was terrible weather lol, thanks for watching mate!
@@VintageEngineRepairs You are just like me that way. I know I can wait a few minutes and things will change but.... I want to do it NOW! 🤣
Great video Tom, you sure have done a fantastic job it runs and sounds great 👍 👌
Thank you Nev, I really appreciate it mate!
I do enjoy watching your videos. Its nice to see how your work and compair it to what I done with these B&S engines.
Only thing I suggest with this video, is the setting/checking the valves.
Other than that, right to the point, not much off topic talking and clear video's.
Awesome job 👏
Thanks for the feedback :) much appreciated!
Très bon travail,felicitations
Thank you!
Brilliant restoration Tom absolutely green with envy I would love to have one of those well worth the effort !!!
Thank you! They’re lovely little machines :)
I found a partial restriction in the fuel tank pickup tube on my old Briggs mower that caused mixture problems.
A little oil consumption might be from worn valve guides.
Yes I have had that too :) thanks for watching!
Brake hone has worked for me to deal with a bearing surface.
Thanks for the tip :)
Curious stuff!
Thanks!
Great vid, really enjoyed it, thanks. But bro, the kitchen sink? Your better half will string you up! 🤣
The Mrs wasn’t here 🤣
Loved the content! Could you show how the linkage bits are arranged? I had to rebuild a similar type of carburetor on a 3.5 hp. Briggs and Stratton reel type mower, and I had a time getting the cable ends, springs, washers, and such back in the correct locations and holes. Not 100% positive they are correct. It does run, but I am not convinced I put it back where things are supposed to be.
Possibly you cover that in a previous video?
Thanks for the kind words :) - I don’t have the machine any more I’m afraid!
I seized my Honda mower the other day (no oil). So I sprayed wd40 in the crank vent to lube up piston plus oil of course and got it moving again, inspected the cylinder and luckily no scratches were visible. Still runs first pull
Nice! Glad it’s running :)
Love the Classics easiest carb to work on and they keep on running.
So true!
I have not seen a diaphragm carb with the small fuel tank before. Usually its the deeper/larger fuel tanks that has the diaphragm.
Also, I love how these engines just never die. All they need is the regular maintenance and love.
Really? I see them quite a lot here! Thanks for watching :)
So true!!!!
Nice job Tom. Would have liked to have seen the ring gap on that old oil ring, it looked completely knackered. 🙂
Hey! Thanks :) I know, I filmed it but couldn’t find the footage after! Gutted, it was huge!
As far as the bolts for the carburetor mounts go, I have always wondered about that to? I've always just used a wrench to loosen them up and then i used a really long screwdriver, that was long enough to clear the fuel tank. But I have wondered why they used that style of bolt? Was there a purpose for the double sloted head bolt? Or was there a specific style wrench? I just thought it was like that for the different angles? Because of the exhaust and the carburetor were in the way? I guess they wanted it to be idiot proof? Or were they just trying to confuse you?
It’s annoying isn’t it!!
The greenies will love you 😂😂
I run an extra splash of 2 stroke oil in the tank for the greenies 😎
I wouldn't think twice about it and I would replace the Rings because of how much wear was going on in there. But I am sure that you will make a responsible decision and replace them?
Correct :) haha
That motor came up well Tom. The old story was those alloy Briggs and Strattons weren’t re-buildable. That is apparently not true. Good tip on the HCl to remove the alloy from the crank. The biggest problem with those motors was the pulsa jet carby. It was crap. I was never a fan of Briggs and Stratton motors but they were always the cheapest option and you paid for it many times over. Jeff
Thank you for sharing! I really appreciate it :)
Came from john klem. Cheers
Haha I love John, he’s a good buddy!
I out fuel through the carb ima try to put through the spark plug today
Sure :) on a 2 stroke always put it through the carb; on a 4 stroke it doesn’t matter, either or!
As we say: like Doxa! :) Thank you!
You’re welcome :)
Great job great job i'm across the pond here... And I found your videos to be so informing... Wonderful keep it up god bless
That’s fantastic, welcome to my channel :)
Great video. 👏🏻👏🏻 Are those oil bottles only available in Australia? Look very handy !
Hey :) they are also available in the uk, but quite expensive nowadays, they’ve gone up. I recommend these ones! amzn.to/3TWZV2t
Great video! Love the old Briggs motors, especially when they can be saved from the scrap heap! I'm curious tho - could you share where you got the wash bottles with the brass nozzles?
Hey! They’re stupidly expensive now days and very hard to get. I recommend you use these : amzn.to/3TWZV2t
@@VintageEngineRepairs Thanks for the info. I figured they wouldn't be cheap, but they are sooooo cool! Thanks for the great content and fast response!
You’re welcome :) the ones I use are called Pressol oil bottles. You can get them, but it’s overpriced nowadays! They use to be affordable!
If you aren't a professional, you'll do till one get's here. 👍🍻
Haha thanks mate 😀
Tom just read Victa have a Recall on the 70th Anniversary Model Lawn Mower
Interesting! Do you have a link?!
23:45 new rings are the smart play, since you have it apart anyway. But were the old ones worn? Excessive end gap? Visibly Scored from low lube? Just curious. I love the put put put sound of the Briggs horizontal shaft engine.
Hey :) yes I lost the footage of the ring eng gap, it was HUGE. A few millimeters!
@@VintageEngineRepairs I have a McLane edger that has a 3HP Briggs that seized because of no oil. Just like the one here, most of the damage was on the flywheel end of the crank. Main journal also had aluminum transfer. I paid $7 for a NOS con rod and used acid and some 2500 grit sandpaper to fix it. It is my favorite little yard tool now.
Great job in rebuild😊
5 hour first oil change?😊
Thank you! Ha should do yes!
Time stamp 4:00 are u putting oil in spark plug or gas I need to do that on mines
I think it was fuel to eliminate the carburetor being the issue :)
By lapping the valves didn't that tighten up your valve lash?
Not really, unless you lap a lot! There is quite a large tolerance allowed.
4:55 oi, i 'ope Greta doesn't see this!!!!
Haha
They stopped doing points in 1982
Thanks 👍👍
Those handlebars seem to be sized for a dwarf!
LOL, elegance mate!
Points to electronic was in 1981.
Thanks!
Are you sure? - I have worked on several of the engined in the video from '80 that were made with electronic ignition
@HobbyMotorDK You would have to look behind the flywheel to see if the block was cast to receive points and condenser. Some models may have been converted in 1980.
They can be converted by just changing the magneto.
I meant that the original parts list showed electronic coil as the OEM part for 1980 dated engines
24:50 no gasket ?
It’s on there, I reuse the original. It’s on the cover side, hard to see.
@@VintageEngineRepairs ah right , thank you for the answer and for all the videos
Nope. I have my dad's 1981 Norlett rotavator and it has points.
I love points ignition! Very reliable and serviceable :)
Heah, must be a very short person that owns that mower, or they were never made for gifted taller people
Thanks for watching!
