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!
Jeff, I hope you are still kicking and in good health. This is by far and away the best video to repair/replace auto choke, repair carb on Briggs& Stratton. I tried doing this with a couple of other videos, but they were incomplete and hard to follow. Thanks!
Thanks for watching~
Perfect. Did not realize my air vane spring was missing. Kept having to manually hold that choke lever closed to start. You saved me a ton of grief. I have been running a cheap Chinese replacement carb from ebay for 3 years with no problems. I suspect even the carbs Briggs sells are marked up Chinese carbs also. Can't go wrong for $12 for carb, spark plug, gas line, air filter, and gaskets.
I really enjoyed the bonus footage! So THAT is what I should have done with my aftermarket carb! If I had known this sooner I would've saved myself a boatload of grief!
In a word "Brilliant". Well done, and thank you for taking the time. Love the fix on the cheapo, superb!!!
Thanks, you helped me solve a like problem with a neighbor's Snapper mower. The missing spring was the cause for a "No Start" auto choke engine!
Thank you for explaining all of that. Someone wired open my choke and I never knew how or why or what worked. I just knew if I removed it, I couldn't get it to start. Now I'm going to order the correct parts and see about getting it working as intended!
Thank you so much! You saved me from having to buy a new mower. I have the same mower and I had tried everything. I could not figure out why it was running so weak until your video showed me that it was the choke mechanism. It was all out of whack including that little spring which was bent up and dangling from one hook. Now she runs great again! Thank you for such an informative video!
you are welcome! thanks for watching
Aftermarket carbs are MUCH cheaper and work fine if they're installed correctly and parts don't get lost or broken. $12 vs. $45 for oem.
Chris Insig absolutely.
true I use aftermarket all the time
I use chineese aftermarket parts all the time and haven't had any issues *yet. Heck, I've also had great luck with predator 212 engines (Honda clones). Still a good video! I love watching small engine repairs. Every now and then they really help out when I get stumped or pick up a trick, tip, or forget how something goes back together. Appreciate the videos.
eBay and Amazon are where I buy 95% of the parts I use in shop
I envy the kid who dare take his father's lawnmower apart in an attempt to repair it. Granted, if he didn't learn from his mistakes, it's moot. Hopefully he watched this video.
When I get one too fix , it usually cost the customer more for me too fix there screw ups . Parts missing , completely putting wrong parts on it- that there's no way it would ever run again .
That’s how I learned dad bought the parts and me and my brother tinkered also learned the mower won’t start without the blade on
Cut the rubber fuel line (from the gas tank to the carb) in the middle and insert Briggs and Stratton Fuel Filter # 298090S. This should prevent any future fuel clogging issues. Replace the filter every 5 yrs or so. :)
A tech out in the field will NEVER suggest that to a customer and we know why :)
If a customer suggests it they look at you in pious amazement and shock like suggesting an inline filter where there is none existing is blasphemous heretic words....I'm thinking specifically of fuel oil furnace deals
Thanks ,,, just fixed my mower ,,, runs like a champ now
Great job!
I thought I was having an issue with my auto choke..
Had previous problems with the carb. The bowl was corroded around the edge and the gasket very iffy, so replaced the whole thing, only to find it was the choke. The arm wasn't swinging. Took it apart and somehow the metal on the choke was on the wrong side of the carb choke arm.
The mower was starting now but still idling low.
It wasn't until you showed the part on bending the throttle spring clip that I noticed, mine was shunted right in.. Bent it back out and the thing leapt right back to life again.
Great video. Wasn't expecting it to be a full tune up, just the choke replacement, but you didn't really show an actual choke being replaced.
Very very good info though.
Those Briggs & Stratton Quantum engines were very good if they were taken care of. You're right about OEM parts Jeff.
Nice thorough vid considering you were just replacing a carb, good info indeed. subscribed.
Thanks for watching! 👍
I do Marine repair and you taught me a lot good job!
thanks for watching
When somebody complements you on your work especially from a professional the normal reply is usually THANK YOU !
very good explanation thank
Hap on coil is suppose be .010"...
tks jeff good job
I check head bolts too once had a riding mower that ran for about 8 minutes then shut off . When it cooled off it would start and run for a while till engine heated up again . Traced it to loose head bolts when engine heated up head would separate from engine and would lose compression and shut down
great content enjoyed this
Glad to hear it
You're doing very good job showing all the problems and fixing it but would be nice if you clean the dirty dust mower dech and under the cover just to avoid contamination
Yes! cleaner is better but I decided years ago I just fix them I do not clean them. I fix too many everyday and it would be a mess after awhile cleaning so many mowers. Some are REALLY really filthy when the arrive into my shop.
i like the after market ones.. sometimes they take a bit of playing with hope your good mate
good job thank you
MR. Sledge hammer fixed the after market carb. LOL
he fixed it by replacing it? He sounds like a briggs salesman
The aftermarket carburetors I've bought have given me no problems and are about 1/4 price as a OEM one...I bet they are all made in China under different brands stamped on them so they can jack up the price. With clever marketing, you can sell ice to eskimos....
I've had great luck with these China made carburetors , out of the last 12 I've ordered only two were sent back . Only one that would run right and the other one as throttle body was designed wrong for my model . Always buy when you can have the free return policy , bought one off eBay with a additional $1.99 three year warranty - kinda of guarantee it would run . No difference in price between eBay and Amazon , cause I tried Amazon and had too return it and went with one from a new one from EBay . My experience 👍
thank you for posting. please clarify your point of view on generic replacement carbs.
Also known as an " aftermarket" carburetor. Any carburetor not made by Briggs and Stratton. Using genuine Briggs and Stratton manufactured parts is usually the best way to go even though it is often more expensive.
Good Job....!
Can’t believe you did not clean the grass of the mower deck and then dumped all the screws on the deck. You seem to be very knowledgeable but your work habits need some improvement.
I managed to fix the auto choke lever there’s some bounce to it now I had to redo it so many times but in the process I got my bolts mixed up I was having problems putting the engine cover on and then the little side piece that goes on the outer part where the engine cover is above the carburetor or an air filter anyways thanks for your help I’m really new at this if you don’t show a step I’m certainly going to get messed up by it but thanks for your help.
There is a tiny spring on the choke arm by the carburetor, make sure it is attatched
Jeff, I am very greatful of your closeup video explaining how things are attached, and work together. I rebuilt the auto choke carburetor, and when put back together and running, it has high r/p/m/, then drops severely low r.p.m.s then corrects itself to high again, then drops severely low. what causes this to happen? Is the choke arm actuator not attached to the other side properly? THUMBS UP!!!
Not sure, with 45,000 views, why this vid doesn't have at least 1000 comments.
I loved it. One of the very best instructional vids I've ever watched on TH-cam, complete with personality and humor. Genius.
Great touch to the ending there Jeff. I had the same issue a couple of times. once with the Briggs Carb, and once with a Honda Carb, that right out of the box was leaking gad like crazy!! I had one of the plastic ones I bought, and it was missing the Butterfly inside the carb!!!
You do great work but I do love m K country music. Also Briggs and Stratton engine coils sets on .10,according to the Briggs manual
This is the video that I needed to watch. With the engine cover off I can see all the parts and where they attach was confused before. Thank you for showing close ups with the camera still this makes it so much easier to see what you are doing. I have a Briggs and Stratton Gold 6.75 190cc lawnmower and couldn't find a video that educates me on the parts and functions until now. Thanks for a great video. Can you recommend what type of gas to use? Is it boat gas?
Glad it helped. Regular gas is best, non ethanol gas if available. I think non ethanol is same as boat gas
I got everything Jeff except throttle return spring part number the one on my motor doesn't look like yours it's larger and it does it run that well
Jeff i think we need to re qualify your statement to say "Dad's should only allow their kids whether it be boys or girls to repair their lawnmowers after they have watched a TH-cam video covering the same type of repair required." My son has been running Eliminator Performance Small Engine Repair for 7 years and has a TH-cam channel just like you. As a 71 year old father that is extremely proud of his son for what he has accomplished and extremely educated by both him and all the other TH-cam small engine repair channels i can honestly say that not only can i repair anything small engine related from watching all these excellent and some not so excellent videos but anyone else can also. This is an excellent well organised and edited video you have supplied for all viewers and really surprised there are 3 haters (likely aftermarket carb sellers on Amazon). The reason the kid broke the linkage connection piece off the carb is simply the hole in the plastic on 99% of the aftermarket carbs is always too small and by simply drilling it slightly larger it easily goes on. I have spoken with my son and he agrees and says that even he has had some issues using aftermarket carbs but for the price his customers usually opt for the aftermarket simply because of the cost savings. He also notes that over 7 years of repairs there have never been any re service issues using aftermarket carbs but has had to return a few to Amazon for ie: will not prime issues or bad aluminium casting of the carb causing voids or cold shuts. Keep up the good work love watching your videos and stay safe and healthy and social distance.
Great info! thanks for the comment! Kudos to you and your son I will check out his TH-cam channel
Jake has an excellent channel also. Been following him for quite awhile.
Jeff you do a very good camera work and in explaining what you are doing. I wonder what airport you live near. I love to hear those planes. Thanks for the videos.
Thanks friend. PDX
I enjoy country music,Jeff!!
nice
Jeff. does some Toro lawn mowers come without a needle seat. Took my needle out (model 20017) and there was no seat but I put one in from the new kit. Fuel. pores out the filter. Just saw another video and his didn't have one either which makes me wonder if I need to remove the new seat? Thanks for your videos.
I change more when they wreck them out and break stuff
Know quick clean down lololol crazy Jeff lolol
Nice fix Jeff: I get the auto chokes often that people put the plastic choke lever on the wrong side of the muffler bracket. It rides against it like you showed not over it. Thanks for great video's.
thanks for watching and commenting!
Hi Jeff and thanks for your videos. I’ve got a Troy built w/ Honda motor. Won’t start and I believe the linkage and springs are not in correct place.
aw dang
Okay got it together like you showed and vrooooooom. New mower given to me cause wouldn’t start.
I just replaced the original carburetor on my Murray with a $10 ebay special and it came with the air cleaner gasket and an air filter that looked as solid as the original with free shipping. I guess only time will tell, but $10 v $50 seemed like the better choice with a free gasket and air filter. If it lasts two seasons I’ll be happy.
I hope it works for you! Please report back
Jeff's Little Engine Service if it’s any constellation, I did take the factory one apart and ordered a replacement needle and seat. It’s on standby to swap the cheapo out if I binds up. Thanks so much for the great information in your videos.
@@Joebanker80 So how is it ? 2 years later.
@@craigtodd8297 Sill running fine with no issues. I let it run completely out of fuel at the end of last season.
My choke is always in open position .
What do I need to do to fix this problem?
Great videos but FYI there is a 1Khz tone in the background of the audio that is very annoying.
Not a good system but twice as good as the Honda one
You did it right haaaaaaa to the aftermarket one.
I bought an aftermarket Briggs autochoke carb on Amazon several years ago that was purported to be OEM.
My customer wanted a Briggs one so I got him one.
A while later I needed an autochoke for one of my mowers, the aftermarket ran fine, and it was less than $15.00 as I recall.
Still using the mower after all the years.
Is that the biggest hammer you have?
Many times things have very forcefully been introduced to the driveway, here.
Sure. The “Kid” did it. Wouldn’t be surprised if the guy did it himself and tossed his kid under the bus. Lol
lol! possibly
I have a toro SR4 20381 walk behind mower and there is a very fine small coil spring that wraps around the butterfly choke shaft and has a half loop on it has come off and not sure where it goes any help would be appreciated
is this it? th-cam.com/video/Xg4ZTM3qL9Q/w-d-xo.html
@@JeffsLittleEngineService no not that one. this is on the carb it's wrapped around the black plastic about 8-10 times and has a hook/ half loop on the end that hooks to something and not sure to what. It has to do with the butterfly inside the carb to make it close to start.
My auto choke lever the one that you’re pushing and it springs back mine doesn’t spring back as much as yours I’ve taken the engine cover off multiple times and made sure that whole arm is in the correct place so I don’t understand you have more mobility in your video than I do.
There is a tiny spring on the choke arm by the carburetor, make sure it is attatched
Why does my Briggs engine back fire at high speed
The auto choke on my lawnmower keeps switching on off continuously, what would be the problem please, maybe the auto choke assembly itself?
auto chokes rarely fail. I would make sure the tiny lever return spring is in place
@@JeffsLittleEngineService Actually not sure if it is the regular auto choke system. It is a harry lawnmower. The lever mechanism that opens and closes the choke that is continuously pulsing on/off is connected to a pivot that goes into the engine and is not connected to the exhaust as they normally are. It also has a bubble to prime the carb. Is there a way I can send you a picture of the mechanism please?
The new auto choke isn’t to bad!
It works great! no issues that I have seen yet
Hate working on one that somebody's already been into that had no business too work on .
it definitely can complicate things
Great video... with all details shown. I have exactly the same engine with auto choke but I have one problem. It start good when the engine is cold. After 10minutes, it wont start again. The auto choke lever already moved to the front and the little choke throttle is open. Everything looks normal. After a while, I can start it and get a bit of smoke form the exhaust. Without airbox, I get little backfire. Is the card to rich? Once it started again, and it comes down in revs, it really stuck at low rev, nearly going to die. All of a sudden it catches up an runs perfectly fine. Any idea, Jeff?
something is fucky
the aftermarkrt carb would have been fine till the son screwed it up
Very much agree.
Loose bolts.
Spring missing.
Broken throttle actuator.
Boy can't fix breakfast,much less a lawnmower.
What do you normally charge for this kind of job? Carb and choke work? Thanks in advance
Depends...usually $50-$75
Jeff's Little Engine Service thank you! I’ve been collecting unwanted lawnmowers, fixing and selling them. I’ve had a few people ask me to work on some but I didn’t know what to charge.
I have had great luck with the Chinese carburetors. $8 and away we go. I noticed no difference other then price .
Good to hear. Unfortunately I have had mostly bad experiences with cheap aftermarket carburetors.
@@JeffsLittleEngineService Me too and I will gladly pay more for OEM, learned my lesson a few times on some GM Auto parts, not only that I buy locally as it helps with our local economy and not China's! Way too much Chinese crap in the sores as it is!!
why drain the tank. most just clamp off the hose. I question whether this rusty old mower is worth the cost of repair repair
You need to make sure you have a clean fuel tank
The funniest thing I learned today:
Confirmation bias: You were so sure it was the after market carb, and when you found it was just incompetence you still blamed the Carb.
You overfilled the gas tank and then had clean it up just to drain it all out. Did you expect to mow half an acer?
The GENUINE, "fancy dancy "Briggs and Stratton Carb , from B&S, (799866) is made in China.🤣🤣😂🤔
"It was not all the missing/improperly installed linkage and loose bolts or plastic parts, 'the kid probably broke': it was the carb".
But really: you do not blow clean everything around the brand new carb you are installing???
And then you double down on "it is the carb" and smash it.n
Too Funny: It was Agathe all Along.
The auto choke system is crap. I would love to see a video explaining how you can delete the auto choke system and add a manual choke carb.
Just put a carb on that has a choke and hook a cable to the choke . Elementary my dear Watson
Very knowledgeable mechanic but I kept hoping he'd take 20 seconds and clean that dirty, oily debris from the deck.
Very good indeed, as an old engineer i would wonder why you don't work at a higher level (i mean me being an old engineer)
I'm not holding the. Chisel for you
lol!
I hate those stupid plastic to metal decks
they always have frount end problems
That's carburetor abuse lol
If you would clean your equipment you would not have to repair it.
well....maybe. I don't usually clean customers lawnmowers for them, I do clean the compacted grass underneath
@@JeffsLittleEngineService your a nice guy. It was a joke. I know your in the repair of others problems. Good video.
If you don't like country music, then I am going to delete you !!!!
I like older country music, not this new crap.
After market=Chinese
When disassembled you can really see what a piece of plastic crap these new engines are.
These companies know cordless are arriving fast so no quality is put into these soon
to be replaced gas units. They know!
gas engines more power better for larger yards
Yup keep buying that junk oem is the best and you guys that keep buying that junk will put Briggs and Kohler outta business real soon
aldric Racette They are putting themselves out dumbass
aldric Racette 😂😂 ok considering they’ve been ripping people off on parts for years.
