1974 Briggs & Stratton 3HP Motor Restoration [Part 1 and 2]

[@ElectricSwordfish]

I have a '77 Briggs that has a slightly different fuel tank but it's essentially the same exact engine as this one. Actually in the process of making a see-thru cylinder head for it and got rid of the points system all together because it too far gone to be saved...have a video of it shooting flames lol. Anyways these old Briggs engines are cool to play with, love the simplicity of them.

[@LookingForEntertainment112]

I heard a Hadeda in the background and instantly knew you were in South Africa! Lol, such a distinctive bird call.

[@AJRestoration]

Hahaha yes you cannot mistake those bird's call!

[@stoveboltlvr3798]

Good job. Those little B&S engines are fun to work on.

[@AJRestoration]

Yes they are

Wish you had live chat going so we can chit chat live while watching.

Thanks for the tip!

[@thebigchieftractor2105]

Amazing job, turned out like new. Looks to be the same or at least similar to the engine on my resurrected Morrison Olympic reel mower, after reading the text at the end I'm glad to hear I'm not the only only one who has issues starting with this type of carb... mine always needs a little gas straight down its throat for a cold.

[@AJRestoration]

To be honest, I hate these diaphragm carbs. I seem to never get them right. Even with a brand new diaphragm it still wont work. It sucks gas up from the tank, but it does not pass through the carb. All the passages are clean, I checked like 13 times. Its as if those little flaps on the diaphragm does not do its job. I just gave up eventually. It starts right up if I gave it some gas through the filter, but dies as soon as it is used.

[@KainKustomGarage]

Looks Awesome! Love those old Briggs motors!😁

[@darrenashley126]

Using the old gaskets I would have used Stag paste (Red Paste ) for a better seal. Just my opinion. :)

[@rustygnutts6255]

@19m01s the 'cone washer' in your Left hand goes on the bottom of the spring with the valve-end slid into the hole... this puts pressure on the intake valve to pull the valve into its seat for compression&power strokes. Else, your intake valve is left bobbing around... it will let your compression blow back into the carburator... AND burning gases will/can get back to the Carb ! *Same little 'cone washer' for the exhaust valve to hold it Closed during intake/compress strokes. Quick check: remove the Spark Plug & put some oil on your index finger, then press on the Plug hole while Helper pulls the starter rope (not gently, but not so hard as trying to start! to check for compression) I forget the PSI, but good pressure will blow past your finger easily. * @34m50sec IntakeSpring and @34m58sec ExhaustSpring is just placed in there and the valve dropped inside the spring coil... *! No Cone washer !* ... each spring must exert pressure on its valve to hold it closed ! When the cam gear high-spot pushes the Lifter - it is working against the spring to open it Just for the Intake/Exhaust cycle. You have No connection that controls your valves... they are loose.

[@Austeration]

Wow she turned out great. My favorite part was you lapping the valves. I did so many years ago and I hated it but watching you do it now was very relaxing. Glad you got it finished. You did a top job 👍

[@AJRestoration]

Awesome! Thank you!

Good morning from Southeast South Dakota

[@valmirramos4195]

Valeu meu querido! Ficou muito bom 👍

[@petertothpete6518]

Sweet paint job! Not sure of doing all this and not checking tolerances (ring gap, con rod ID. crank journals, upper/lower bearing ID, etc) though, unless you just want a nice shelf piece. As for the carb, if gas is getting to the upper bowl, the diaphragm is fine, that's all it does. Behind the (mixture needle) jet are 2 or 3 tiny passages that will clog preventing fuel from getting pulled up from the upper bowl. Also make sure the smaller pick up tube is sealed tight in the carb and has no cracks/splits. The gasket in between carb and tank is critical for proper seal for the carb to be able to produce vacuum to pull up fuel as well. Another issue I've found is people not backing out the mixture screw before tightening the nut jamming the tip of the needle into the jet, ruining both. Lastly, I've had issues with China carb kits. I stopped using the needle, jet, and diaphragm/spring/cup out of these and went back to OEM or Stens when OEM isn't available. Made a world of difference for me. Didn't mean to turn this into an essay. Hope this is of some help and you get her running right.

[@AJRestoration]

Thank you Michael, I am glad you find it relaxing haha

[@filernestopaculan5351]

thanks for sharing..how to restore

[@MegaBosX]

A question i have always had, how do you keep track of what parts go where when disassembling so that you are able to assemble them correctly

[@AJRestoration]

I normally use the footage of the disassembly to backtrack if I can't figure out how and where. After a few of these restorations, you get a feeling of where every part goes.

[@mearns89]

Lovely restoration, try and keep the original stickers in future projects they have so much charm even tho they look a bit tattered. Digital print is not the same as old litho printing.

[@AJRestoration]

It is nearly impossible to save the old stickers when sandblasting or even when using paint strippers.

[@mearns89]

@@AJRestoration It can be difficult but a good solution is to use a heat gun and a blade the heat gun softens the glue and comes off a lot easier. Easier said than done and I’m sure you’ve tried. But always worth a go

[@Kangsteri]

The missing link I came to see...:D Let me know the measurements for that air governor- and choke rod if you make this run someday.

[@TheJHA67]

Where did the gaskets go? .. They help to create clearance for the oil for the support bearing for the crank. Became very nice that engine, like new :)

[@campionoverbagh561]

Love it! Just wondering about putting paint on the governor vane....change the weight?

[@kevinjohnston4512]

Best motor made.

[@peterduxbury927]

What?? I have not seen a single ball (or Roller) Bearing in any part of the B&S engine. Take a closer look. Give me a Honda every time.

[@AJRestoration]

It all depends on the owner of the engine. Yes roller bearings are better, BUT I have seen Briggs motors outlast Honda motors by far JUST because the owner looked well after the engine. I love Honda, Kohler, Briggs, Onan, Ducati, Robin, Kawasaki, Tecumseh, Victa, Rotax, Villiers, Suffolk, Yanmar motors equally. Each engine has its strengths, weakness. But I understand what you are saying. If you want reliability, just go Honda or Kohler.

[@bigDbigDbigD]

Question: Was any surface prep done between sand blasting and powder coating?

[@MarkMeadows90]

Yep, can't go wrong with a Briggs. Those engines are tough machines, and easy to work on and service. I probably went through about 5 different B&S engines on my first go cart back when I was a kid. Trying to determine which one my father and I seemed to be more powerful and faster. Modified a couple of 3 and 5 horsepower variants. Turned out, a 6 HP was the best at all around torque and speed.

[@smashyrashy]

We dont want separate videos if you are going to do this regardless

[@AJRestoration]

Sometimes these projects just take too much time, and I have a weekly upload schedule. So if it takes longer than a week, it gets split.

[@kowalskikowalski8080]

Is it even necessary buying expensive oils for small engines? All these rebuilds, the internals are so clean.

[@AJRestoration]

Expensive oils? no as long as the oils are in spec you are good to go. SAE 30 for almost all these small engines.

[@WILD35]

My first go-kart had this engine it last a long time two years running till I have to replace for a bigger and powerful engine

[@AJRestoration]

I just love these little Briggs engines. I have a nice 9hp one waiting in line for a decent restoration.

[@vornamenachname1796]

37:55 no sealing ? 😮

[@bigmesstest230]

You know that the lifters dont have to go back in the same spot right the bottom one can go in the top and the top one can go in the bottom

[@AJRestoration]

I have heard rumors that in a used engine its better to keep the lifers in the spot it came from. Not sure if it would make any difference. I did wonder about that though.

[@slimwantedman6694]

Looks like someone was running ethanol through it. Never use ethanol in them small engines. Hell I dont run any in my 5 pickups.

[@AJRestoration]

I had the same suspicion. These little engines do not like ethanol unless it has some upgrades.

Why do you paint some and power coat others?

[@moorekyle99]

My ocd screams because the head bolts don’t match. I know I’m not the only one.

[@rickygibson3754]

so when you say restore you mean a paint job with spray cans no less and no case or tank gasket or gov. vain spring and you left the kill wire off the carb body but since it did not run dont guess it matters
