I thought you were doing my mower. Looked exactly like I had the same problem. 10 minute fix. Thanks
OMG How Lucky am I...was walking the neighborhood and saw a "free" mower that looked in good shape which they said was not working for likely "user error" I grabbed the van and picked it up and it did exactly what they said with start once in a while then blow smoke and go out but not start other times. Played around with the spark plug and nothing...Found this video and with my own fingers bent that one metal piece you mentioned to help close the choke and BOOM! Started right up, shut it down and BOOM started right up again! Whoo hoo and thank you for this video.
Typically cranks first pull. Ran for an hour, stopped to change oil, and it refused to crank. I changed spark plug, cleaned carburetor three times, and adjusted valve clearance - no joy. Everything at rest: the choke valve was closed. Did your bend the bracket tip to forcibly hold the choke valve closed and it fired right up! TIL: I don't like auto-chokes. I was ready to toss it. You saved it. THANKS!
We're not worthy Don! You are the wizard of small engine repair/troubleshooting! Appreciate the upload! Cheers!
Camera work very good as well. Showing the size and position of the springs helped me find the springs I needed.
Great i tossed a Briggs and Stratton powered pressure washer 2 years ago cause i couldn't get it to start. Thanks for the info
Mustie1 probably has it now :)
Brilliant short and informative information on this problem and how to sort it . Thank you from Ireland 🇮🇪
I have fixed a lot of my friends small engines and its funny how the simplest things create so much problems. Sometimes you have to think outside of the box. Well done
same mower is mine 7.25 awd but i dont like it much wheels wearing out allready darn plastic wheels and bogs down when mowing and its 2 years old and issues wich im replacing it next year with a 9.9hp honda 21'' shaft driven mower
True. But this fix is not thinking-outside-the-box. This is std choke troubleshooting.
@@michaelmactavish1728 IT AIN'T GOT NO GAS IN IT
My brand 1 yr old 775 had a butterfly was just flopping around. Had to take entire cover off to get to one screw holding carb cover in place, but thanks to vid it works now without having to bend armature seeing as it seems was never hooked up right at the factory. Common problem Briggs? Much appreciated for the help here!
Thank you heaps mate, Been years with this mower constantly using start ya bastard to turn it on.
Enough was enough i was ready to pull it apart completely to find the problem - you just saved me an absolute headache you legend - Turns out the butterfly flap was stuck open from a weak return spring thats showed in this video.
Currently I was looking for a new lawn mower but I've seen people write avoid the auto choke because they fail. Before I buy I'm going to check how the auto choke is assembled to see if it's like yours since that's a visible easy fix.
You gotta love the simple fix issues. And you got to use power tools. Win win.!!!
Just watched this and fixed my mower in like 5 minutes m. Perfect video bro. Thank you!
Check the brake cable first, similar symptoms, the cable doesn't need to be broken for the machine not to start.
I had an identical machine the other day similar issue but it was a stretched brake cable, it would pull over without any problems but there was no spark.
ARednecksLife yes that can happen. I have a video on that specific problem on my channel.
I run in to that a lot. People store their mower outside and the cable rusts up inside and freezes up. Then when its pulled, it stretches and breaks the strands in the cable. After that no spark.
RC Hobbyist Extreme That’s the problem I had...
Bob Dylan If there is no adjustment, may need to replace the cable.
I have adjusted some, if I remember correctly bending the piece near the flywheel brake that the cable attaches to to keep it from grounding out.
Dude, you are KING!!! That just happened to be the solution before I knew I had a problem. Please please need help with Coleman Powermate 4000w generator
Thank you. This more or less fixed my issue. My model had a plate protecting the spring and lever controlling the butterfly. The plate was slightly bent inward so it stopped the lever from releasing and closing the choke. A tiny bend outward and it fires up first pull again!
Thank you so much Don for teaching us this trick 👍👍👍. It was very very helpful
Thanks a Mil Dony you saved us a trip to the mechanic!
All the best to you.
This video helped me get all my springs and control levers on the carb back in the correct spots after a stick rammed into my carb and pushed all the springs and levers loose, and bent up my choke actuator rod. Carb area needs more protection from debris on these engines.
I agree 100%. Same thing happened to me.
awesome , now if i see one of these at the landfill site i will snatch it up ..
allot of people would have thrown this out and just bought a new one ..
good work
Thanks for the tip!
Woooooow!!! If life was as easy as this video!!! Thank you!
i hope this is the problem with mine..it snot a husqvarna but this is pretty much the same mower i have and probably the same problem i did eveyrthing to it..this guy is the small engine genius ..ill try this out i hope it works. i had an extra spring too and i see wher eit goes here so ill fix that also
This video has helped me view the spring placement on a Briggs 175 cc ( same setup on mine as this one ) that I had got given to me , and a plus on the auto choke too . Thanks a bunch .
Another great video, DonyBoy.
I noticed that the choke linkage has an inverted U in it. You can see this at 3:06 or 3:45. I wonder if the purpose of that loop is to facilitate adjustment to the length of the linkage.
At any rate, thanks for showing us this.
I'd been working on my mower for hours when I came across your video. Takes a smart guy to think that thru. Thanks!
Glad to help!
Thank you! Only thing I have to add is whenever you do mower and weed eater repairs please include close up shots and a detailed description of how the linkage is supposed to go. A lot of videos on UA-cam don't show that at all and I can't tell you how many hours I've searched and searched on UA-cam for numerous engines trying to just find how linkage is set up. I appreciate your videos they have helped me a lot keep up the good work!
Thanks a lot, I fixed my lawnmower today. Great video.
I just ran into this problem and couldn't figure it out but that's exactly what the problem was. Must be a common problem with this model. Dk how it happened but after going thru all of the obvious things then buying new air filter, sparkplug,change oil.Thats it! Like you made the video for me. 👍👍
If life was just that simple... Great helpful vid as usual, thanks fpr posting!
Thank you for the great video, it solved my issue.
QUESTION: My Cub Cadet mower recently had the problem of starting up on the first pull easy enough, but then it would shut off after about 20 seconds. The Thermostat measuring part was replaced. After that, the mower would stay on again; however, the engine did seem to randomly be missing beats. The new BIG problem was that the mower takes over 15 pulls to get it to start up cold. In comparison, after having run for a while, the mower starts on the first or second pull. Clearly, the factor of "Temperature" is involved in starting the mower. This mower won't start "cold" easily. The mower actually started on five or six pulls on an 82-degree day. But on a 60-degree day yesterday, it took 15 pulls to get the mower to start. Do you have a suggestion to fix this?
Actually, this will fix many lawn mowers with a similar problem. I had a Ariens/Husqvarna riding mower with a Brigs & Stratton engine that similarly refused to start. After getting tired of squirting starting fluid into the carb, finally scheduled a warranty repair. The shop guy showed me this exact fix. Never had a problem afterwards.
Thank you and thumbs up. Its like with automatic transmission, when they play up the first component to check is the linkage.
DUDE THANK YOU !!! You were a big help I really appreciate you man.
Excellent vid. Did not know this. I have a friend with this exact problem. At 3:54 the U-bend is exactly for adjusting rod length.
I wouldn't adjust the u-bend because it might make the linkage bind on carburetor
He's a great small engine mechanic and even a better teacher!
Thank you for this helpful video! Well done!
AAHH a new problem fixed. Yep they probably were trimming under a bush and a branch went in there and bent that soup can metal. Another great catch and a new idea to look at for diagnosing. Great video. Thanks
I hope this fixes mine I'm gonna go try now
Nice repair i'm sure this will help a lot of people a simple fix good video as usual.
genius - been at it all day - found this video
problem solved!
Nice clear video. I have not hit this problem yet, but now I have new info to file away. Thanks for sharing your knowledge.
Thank you for including the “symptoms” so we can use it to troubleshoot. Mine has a broken plastic part on the auto choke, where your index finger was touching at 1:37. AND the spring is missing.
Just replace the whole carb
Hello Don i have a Toro personal pace 2013 whit Briggs and Stratton motor the problem it's that i works fine mowing 2 jobs but later on gets really hard to start it i have to raise the front tires and pull it few times to start and starts really slow whit black smoke. Thank you
I’ll try that and hope for my husqvarna lawn mower to be working again 😮💨
Thanks mate. Had exact same issue on a Briggs and Stratton 8.50. Appreciate all the effort you put into these posts.
Trying it now. I'll keep you posted 👍🏻🤞🏻
Yep, kinda same issue with those autochoke system ( the bracket being bent and obstructing the choke lever arm from swinging wide open)....
As always your videos are the best👍
I'm gonna go check this immediately. Thanks
Way To Go Donyboy.Simply More Words of Wisdom.From A Master.Donyboy.When Are You Steve Going to Make Another Video.Richard.
hopefully soon
Wish i would of watched this before taking mine to the shop.Thanks for posting.
Thanks for the tip.
Great tip donyboy. Hope your wife is doing well. Have a great weekend!!!
Great information, have a great day.
thank u so much for posting this simple fix..I had the same Issue with the open choke, the lever was stuck in the open position, I manipulated the lever by hand and somehow became loose again and functioning narmally.. i still dont know why and how it was so locked in,,THANKS A MILLION FOR THE GREAT AND SIMPLY EXPLAINED VIDEO.
That's a very helpful video. Thanks for sharing.
Cool, great tip! I'll have to check and see if the same applies to l-head "quantum" Briggs engines: I'd been blaming starting issues on using it rarely since it's just cleaning up after my Rider.
Great Tip Dony thank you.
The u bent in the wire you followed is for doing the adjustment. No need to bend the bracket.
Ok this is similar to my mower.. thanks
Good explanation on the thermostat arm business!
Possibly one can do the adjustment also on the bend in the rod. There is an U-bend that can be squeezed together.
Pretty sure that's what it's there for.
Thanks Don...easy fix just as you said.
Great repair. The owner of that mower keeps it clean. Now I’m interested in the African Twin parked behind you. Maybe a maintenance video.
Lot's of good Education here. Thank you DB73 for your making it simple to understand. You rock !!.
My Husqvarna AWD has a 190cc Honda auto choke hopefully it won't give me any trouble as always great job my Canadian brother 😀 😀
This might be the problem I ran into yesterday trying to start up for the 1st mow...gonna see if this is the issue...usually it's old gas or bad spark plug. Don't often see this type of troubleshooting in manuals.
Thanks Donny, another one of mine fixed perfectly with your videos.
excellent demonstration. Thank you! can you also show me how to increase the speed of the engine. It seems to be running slow in my mower.
Question, I have a husqvarna AWD 725 i think it is with the Briggs engine. It doesn’t want to start again when it’s warm because I have to stop and refuel. I assumed it was the ignition coil and changed that, it didn’t fix it.
Can you point me in another direction, it also has a new plug and air filter.
Nice and simple just how we like them
Worked like a charm! Thanks
Great tip. Always start looking at the simple fixes first. Thanks for this. 🇨🇦👍🏼
Great video thanks man.
Who is the genius at Briggs who decided this complicated, finicky mess was better than a manual choke .lever?
Consumers are no longer smart or motivated enough to use a manual choke. Hell, they don't even want to push a primer bulb a couple times, or check the oil/air filter/blade.
People today are just plain lazy is why. It went from a failsafe manual choke to a stupid primer bulb system now this auto-choke crap.
I have a newer Husqvarna pb105 when it's cold it takes 8 to 10 pulls to crank it that's the craziest set up I've ever seen someone too k it apart I've got it back together cold cranks on 8 or more pulls after hot crank right up can you do a video on the newer version ???? 😢
thank-you bros!
Thanks 😇
What about the reverse problem? That is, if it starts cold ok but after it reaches operating temp, and you shut down to empty the bag, it won’t start hot. Is it still a choke problem. Should I check that the butterfly is open when hot?
I have the same mower... I love it...works great...i tell everyone its mechanicly fuel injected 😆
Very good information
Thank you
Thanks!!
Always good when you can fix things without spending a penny.
Great work as usual Dony.
This helped me but I used a zip tie to hold it closed until the mower heated up and then I cut it off
How's she goin'? Choke not fully closed caused me an awful lot of heart ache on a Kohler Courage engine until I adjusted it properly. Nice fix!!!
Thsnks don....god bless
good job
Best small.engine channel
thanks
You Are good 👍🇺🇸
Great vid!
My Snapper has that same engine. That auto choke mount metal is so weak that it could easily be out of position. I had to push mine all the way over until the choke hit the muffler shroud, but it fixed the problem which was “no start”. Maybe the auto choke spring is weak and doesn’t retract the linkage like it did originally.
Great video, informative and quick. Thank you.
Thank's for the info. God bless you..!! 🙋♂️
Its always something designed to make life easier that causes unnecessary problems.
Thank you for the informative video. I don't understand why 11 people clicked thumb down!!
