PLEASE KEEP IN MIND when you are watching my videos: I am showing you the least expensive, quickest "backyard" methods for repairing or servicing your lawnmower or equipment. Replacing all components such as gaskets and fuel lines is always recommended when rebuilding or repairing equipment. With these videos I hope you are able to fix and repair your lawnmower yourself with minimal parts, knowledge and tools. Thank you for watching!
I LIKED THE VIDEO SINCE I AM WORKING ON A 8 HP BRIGGS & STRATTON RIGHT NOW. THANKS
Glad it helped
I spewed water when you said ooooooh in a deep voice
Thanks for the tips on the carburetor. I didn't realize while cleaning it that there was a main jet on the top of the carb. Initially i thought it was just a screw holding the carb together. This helped me get my 8hp b&s on my snapper riding mower working again!
nice work!
Those are fine engines.
Copper spray a gasket, and back in it goes.
Adapt, and overcome, as they say!
I bet Stens or others make them.
BTW, I have one of those in a '85 MTD rear engine rider that a neighbor tossed. Changed the oil, cleaned the carb, been using it for almost 10 years. Still runs strong.
Great video as always. Truly appreciate you doing these videos!!
Glad you like them Thanks!
Good time consuming video , the old Briggs sure were amazing engines . What I remember started out working on . Thanks .....
I agree, Old Briggs are great to work on. parts are usually available
The old school way to deal with an unavailable head gasket and/or do a cheap compression increase is make one out of copper sheet, they can be annealed for reuse over & over.
Excellent advice @markross6818! I love Ol' skool tips! Thank you for commenting. Just like my old 2 stroke Yamaha RD400 motorcycle had. Indestructible! and reuseable time after time after annealing.
This was a very helpful video for cleaning the carb on my neighbor kid's riding mower
Great to hear!
They still sell those head gaskets on Amazon. I just bought one for a similar 1989 8hp I/C engine. It's exactly the same measurements.
Part 2 comes out this Friday 3/5/21 4:00 p.m. Pacific time. thanks for watching!
Can't wait for the return of the "Obsolete" with your mind I'm sure it'll work. Oh mage to another channel it ain't the space shuttle. I would stick the old one back on it maybe with a little copper spray, You the man Jeff
Thanks friend, part 2 will be released next Friday
Hello Jeff new subscriber here. I found a good deal on a Bobcat walk behind mower that had a blown Kawasaki 14 horsepower motor. The next owner used a Briggs 14 horsepower motor and that is where I come in. You sound like you are from the Pittsburgh area but I could be way off. It is getting cold here but thanks for your information.
Nice job Jeff: The Diode is a one way electrical device. Only lets current flow one way, also try some copper gasket spray on the head gasket. I have had great luck with it.
Thanks for the tip!
I have bought 4 Briggs parts and services catalogs off of eBay for repair information and to ID parts. I have gotten many good deals on eBay by looking up parts by the factory part numbers. Many of the sellers don't even know what their parts fit, so they just list them by the parts number rather then list them by what model they fit.
I think the old one will work and maybe someone can find you a replacement part. Great video.
I have the same engine I bought about 8 months ago. The only difference I see is mine has a chrome air cleaner top. I don't buy vertical shaft engines as the norm, but the price was cheap enough I will resell it or part it out and save any parts that can be used on a side shaft engine.
I have an oldy 8 hp B G in mower " Widefield", your video give me the desire to open her up to see what happens ( Seized)
20:10 - Oh ok everyone gives will advice on how to easy it is to take it out hahaha made my day thanks man for the nice video
What a diode is is a one way check valve for electricity what's coming off the alternator is alternating current hidden reason why it's called an alternator and the diode simply makes it DC so that way it charges your battery and do whatever else it needs to do
great info!
im thinking a standard head gasket will line up good enough to work , maybe .. i seen someone use a 3hp gasket on a 5hp..there was just 2 holes needed trimmed out . maybe take it and compare it to some others.
To clean an engine prior to painting gas and a paint brush are handy to soften old grease. Save the brake kleen for last to remove petroleum distillates. To remove rust cheap and easy like on that tin piece, soak in whatever vinegar you have handy.
My old 70's mower has the same carb as the one right here 43:00. I'm trying to figure out what the factory settings are for the jets.
Jeff, what i did with head gaskets to reuse them was to put a coat of copper coat spray on them or silver spray paint. Something thats in silver paint that will seal them up as long as they aren't torn. Yours looked fine in your video. 👍Roger
Good tip!
“ Time to remove this nut , spray a little bit of lube , let it sit , ok let’s try , darn this was a stinker , option “ B” the grinder “. Keep them coming , love your attitude .
Greetings from El Salvador .
thanks friend!
Strip it down further Jeff.. you’ve gone as far as painting it, was hoping we’d see you tear further into it and give it new rings...
re-use the head gasket, try making one from copper sheet, or jump online- somebody out there would have a NOS head gasket
I just clean everything up, and take apart starter motor, carburetor etc... part 2 is next Friday! I am gonna send it
That diode does not decrease voltage what it does is on allows current to flow one way it is basically like a check valve and if you bypass it what will happen is your stator underneath your flywheel which charges your battery will burn up
Hey there's brand new head gaskets on Ebay. Look to see if any of them will work.
Do you know what year or about what year this engine is? I have one just like it off a Wizard 8 lawn mower I'm trying to bring back to life.
The diode turns the electricity from AC to DC all alternators make AC current and need something to convert it to DC
very good explaination thanks!
Finally someone with electrical knowledge .
You have to use the ratchet too.if you don't want use it.always yours screws will broke on the muffler,back and forward easy wd40....good job!
good tips, thanks friend ! I will do that next time
Awesome video. Great motor project. i have a 8 horsepower B and S flat motor in my troy built lawn tractor. i ordered and got a brand new carburetor and head gasket on ebay. i Love the your attention to the details. i just subscribed to your channel and hit the bell thing too. :)
Right on thanks for watching!
I added some gas to mine today Jan 19 2023 and it started running violently poorly.
Shaking and vibrating crazily, it normally starts beautifully
Does snow/water affect the gas like that? Also wondering if the cold damaged anything on startup or bent the crank key
I would start by draining and cleaning the carburetor and fuel tank.
@@JeffsLittleEngineService I did, put fresh gas and replaced the spark plug
Still violently shaking 😬
It Amazes me how you do it I would be working on a workbench to do that no bending over
I have some work benches but the camera angle is best when they are on the ground, The engines are easier to wrestle too!..LOL
@@JeffsLittleEngineService oh ok I see still Wouldn’t be able to do that myself because that would just kill my back I’m amazed how your back holds up so well.
Another 2 cents. When using rust removing products and penetrating oils and sprays, use liberally and walk away for a day or two.
excellent advice
Thats crazy, they made tons and tons of those engines, a lot of okd school snapper rers use that engine, lots of things did. I guess when the new Briggs took over parts on the old stuff started being discontinued. Gotta find some new old stock on ebay, like the Tecumseh. But if thats that metal head gasket, it should be fine, those were reusable unlike the cardboard material made ones later.
Your a great mechanic. I fo wish you'd upgrade your shop.
Thanks friend
I have a similar B & S engine model 170402 built in 1967. It worked when I took it off a snowblower a few months ago. I did re build the carb recently. I can't get it started. Any ideas? Compression is around 52 PSI (which is the same reading I'm getting from 2 other engines that run fine). I do definitely have spark. I replaced the head gasket a few days ago. Now when I pour some fuel into the sprak plug hole and replace the plug I still get no fire at all. I also checked the valves for leakage but when I put some fuel on them when they were closed I had no leakage at all so they seem to be OK. Timing? Spark plug?...it worked on my other engines. So what other options should I look at? I appreciate your videos .
Sounds like no spark I would replace the points and condenser or upgrade to non points style coil/magneto.
@@JeffsLittleEngineService I already replaced the points with an electronic magneto and it is sparking. I think I will check the valves and clean and lap them to see if it gives more compression. Should be close to 100PSI what I'm getting is about 55 right now.
I don't know how your back holds up. You are always working on everything laying on the ground
my work benches are alweays full and I like the camera angle when they are on the ground. They are also easier to wrestle when on the ground....lol. I have a low stool I sit on often when fixing stuff
It’s the main reason I can’t watch a different small engine channel because he leans over the engines usually sitting down , which would cause me days of pain!. Not his or your fault , just difficult to watch for that reason. Otherwise nice vid 👍
We need to organise a go fund me / crowd funding page to buy Jeff a new work bench....
I have a similar engine on my Craftsman riding mower. Just wondering, how much oil does that take when changing it?
apx. 1qt - 1.5qts.
Hello, does this engine have an oil filter? Has an oil drain plug. I am getting ready for an oil change in spring and I would like to know how to go about it
no oil filter
i have an old briggs and tratton but i have problems with elektric start idk what or how i have to fix it
Start by making sure you have a good charged battery. Check that the main fuse is not blown(usually located by the battery). Solenoids fail often. Ignition switches fail when they can get rusty at the connections on the back. Make sure starter motor is not locked up from rust. Good luck
@@JeffsLittleEngineService i found the problem the soliniod is broken but i didnt recieve my new one yet
I reuse head gaskets on my own engines if its a mower that im going to sell i replace it
Oh no this can't be the end rob it of another engine or just stick back on that head gasket that's what I would do ! Now I won't sleep damn ! 🤯 haha can't wait for the next one !
Next Friday I will have part 2!
Try to reuse the gasket . It doesn’t look that bad.
Also are there any aftermarket gaskets available?
Surprisingly I couldn't find anything
I have reused the same head gasket 5 or 6 times and they still work as long as you don't tear them. Never had a problem.
cool, thanks for the info. I think that is what I will do
They still make the head gasket for that motor
I find and order parts several times a day everyday. But I could not find one for this engine. It is possible I did not look hard enough.
There has to be one out there, but how much?
Put out the model, type and part number. Viewers are resourceful.
What's your address. Im build you a work bench. 😂 seriously. 👍
LOL!
I bet it would be nice to have a work bench lol my back would be killing me .
I have a few work benches but they are always full of crap...I have a low stool I usually sit on, I like this camera angle too and not enough light in my garage for filming on my work benches. Some of Part 2 (released next Friday) is filmed in the garage and I had to adjust the brightness alot during editing
I understand.
if you would have used valve grinding compond on screw ,screw driver will not slip
Nice tip!
So just reuse the head gasket me and my friend. We use them all the time and the motors ran just fine what the hell you got to lose better than throwing the trash give the motor chance put the head gasket back and see what happens
I like this idea!
Check pro parts direct they should have what you need.
I looked everywhere for genuine B&S and could not find any. I suppose I should try aftermarket sources a bit more. Thanks for the tip!
@@JeffsLittleEngineService they are an authorized B&S parts dealer. You can also use a coupon from taryl fixes all here on youtube
why can't you reuse the head gasket?
because they are a "squish" style gasket. sometimes you can get away with it
where is part 2??
It will be released next Friday
My 8 hp.starts immediately, but shuts off immediately, runs with starting fluid for 15 sec
carb main jet is probably plugged
So, takes head off before doing compression test.?
Smells like a fake video.
lol! not a fake my friend. I figured the compression was good and wanted to replace the gasket because it's usually cheap and easy to do!
maybe a little late but here jeff 272163S
