Troy Bilt 21" 675 Series Briggs & Stratton Carburetor Cleaning & Start Free Lawn Mower! -Mar. 2,2017

[@VManuel26]

Bought the same lawnmower second hand and stopped working roughly 2 months later. Followed the steps in your video and got it running again. Thank you so much for the help, you are a true champion 🎉

[@mountainbikekayak]

Hello Manuel thank for watching and so glad it could help you get your mower going again!

[@bobmoe5469]

I have EXACTLY that mower and engine. It hadn't run for a full year. I had already tried fresh fuel, new spark plug, and air filter. I cleaned the float bowl nut as you advised and it cranked first pull !! Thanks much.

[@mdbits]

Thanks so much for sharing this video. At 1:25 into the video you discuss the auto-choke valve. My mower would start fine but then sputter out. I changed the spark plug - no difference. Took the top cover off and cleaned out any debris before lubricating the auto-choke valve. MY TEN YEAR-OLD MOWER NOW RUNS LIKE NEW. I will come back to this video in the off-season to give them carburetor a good cleaning. Thanks!

[@JimGaleForce]

Ha. "Not quite right yet." Dude, it runs. That's infinitely better than mine at the moment. I'm inspired to make it run now. thanks!

[@cmciano]

You are a LEGEND! I had the exact same issue and this is what helped me bring life back to my 8 year old mower. Thank for making this video.

[@technogiggle]

This video is an outstanding guide to do an all-out carburetor swap as well. Instead of having to go through the trouble of cleaning stuff out, sometimes popping in a new carb is better, and they're pretty cheap. My carburetor swap went flawlessly. Thanks for the video.

[@civlyzed]

I'm late to the party, but thanks for the video! Someone gave me one of these mowers and this was the trick to get her back to life!

[@gildardocalderilla5958]

Just want to say...YAYYYY....followed the videos instructions. Now my mower runs!!! Thanks again KZbin mechanics...both small engine and car engine mechanics...yall are the sheezay!!! Saved me from dumping out 160-200 bucks for a lawn mower

[@skylerbeaudoin8737]

It WORKED! My mower is back to normal now. Thank you for saving me some money by teaching me how to DIY.

[@bolt4694]

I am no Mr. Fixit. My mower wouldn't start. Followed your video instructions. SUCCESS! Even my wife was impressed. Thanks.

[@f86fman]

I too got the same push mower for free (abandoned to the corner of a shed by a lady across the street whose husband is a do-nothing). Leaked gas like a sieve. Thought it might have a fuel line leak. No. To remove the carb I did not have to remove the mower top cover and fuel tank. Just removed the air cleaner housing, two springs, three carb mounting bolts and the carb just dropped right out. The carb was a mess. Looked like crud from ethanol and old gas. All I did was to free up the float after checking the needle seat. I found that the needle was binding up causing the float to stick and flood out the carb something fierce. I cleaned up the large orifice that the needle moves up and down in. With that done it was 10 minutes to bolt everything back up, and she fired on the first pull. Actually it has not failed to start on the first pull since I've owned it. Mulches very cleanly with a sharpened blade, I'd say as well as my Toro Super Recyler, and that is saying something! Wish this thing was self-propelled like the Toro. Oh well, she works great so I'll just use it on those days when I feel I need more exercise. Nice video, by the way!

[@kelvinboyd7459]

A guitar string is your best friend when you're cleaning these old carburetors

[@Kube_Dog]

I never thought Tom Green would teach me how to fix my mower. Thank you, Tom Green.

[@JoseJimenez-ee2gr]

Thank you I just cleaned carburetor and it's working now. 👍

[@sictransit3500]

Well done, Very thorough! I appreciate the camera angle as well!

[@tassoumaate3293]

Thank you so much. I’ve been using manual push mower for the last 5 years then a friend of mine gave me his machine saying there’s something wrong that he doesn’t know about. It was missing a float bowl :-). Tomorrow if God well I’m going to Lowe’s to buy the part. I don’t know if the kit comes with the bolt that holds the bowl. Your video is great. God bless you my brother from another mother.

[@Flash90716]

thanks for the video! mine had the same issue, i followed every step and works great now. youre a genius

[@tinybusinesses1566]

You should show the carb jets/ports being cleaned, and checking if the air cleaner is clean/dirty, and check the air gap on the magneto/coil - all of which can make the lawnmower run rough if not taken care of.

[@livingthedream1964]

Hey @tinybusinesses1566.....do have a video on how to check the air gap on the magneto/coil...or know of someone else's video on this topic. Thank you.

[@barese420]

that's a nice little hobby you got there my friend thumbs up have a great weekend

[@seangolden6074]

Had same one worked like a charm, and cuts great most the time, i did not take the tank off i just took off the hose from gas to carb bowl held carb bowl line up not to lose the 50:1 and sea foam i put in then i took off the bow check it and it was clean so i just cleaned all the ports out and im good now think mine was bad gas mostly but anyhow always use non ethanol gas some people do not know that or get the additive to take the ethanol out of it from autozone or wal-mart etc but mine was good after replacing the air filter too we are cuttin grass again! Thanks for the video saved me some time on tool sizes i would need!

[@seangolden6074]

Seem 9 times out of ten either bad gas that has gummed up the carb.

[@seangolden6074]

but you really can not take off the gas tank and still get that carb off fyi.

[@anthonyespinoza5340]

Thank you so much with ur guidance and a can off carb cleaner I gat a free lawnmower going

[@Ironliftr3]

This helped me out a ton! Thanks so much!!!

[@taylorbertrim7625]

I have this engine on an Ariens mower... I can't keep mine running, I'm planning on spark plug, filter, and carb cleaning.

[@1anthonybrowning]

I've found the best time to change oil is right after running the engine so it's hot. All the sludge is stirred up off the bottom and viscosity is low so when dumping the oil it comes out fast with all that garbage still suspended in a the oil.

[@mountainbikekayak]

Hello Anthony thanks for viewing will need to do just that. Doubt they ever changed the oil in it there was nothing even registering on the dipstick. Hopefully I can get this running better and do just like you say let it heat up really good and dump that oil out. It is just sludged up but overall a really nice looking lawn mower.

[@neth1968]

hi I have a Troy Bilt 21" self propelled mower 2 in1 Briggs & Stratton 650 series 190cc/650 The interlock switch one prong came off w/o me knowing about. Now I have bought a new and want to know which wire goes where ( This interlock is on the R side of the motor if you are facing the front of the mower) Thanks for your help.

[@joeyoreilly5100]

I gotta problem with the springs on top of the carburetor. Any suggestions? The spring from the START is missing. I'll do what you did, but if there's a missing spring, I'm screwed. Thanks for your video.

[@tonyjandura9654]

my 7.0 hp. b&s intek owners manual calls for a .020 gap on the spark plug

[@mwhich50]

Thanks. You helped me to save time, and at least $100.

[@petesingh292]

I got a very similar lawn mower , it won't start at all . So I replace spark plug still no go . My neighbor told me to check the ignition coil which I did still didn't see no spark . I replaced ignition coil and adjusted the gap with business card just as you mention in your video , still no start . Please tell me what I did wrong . Your early reply will be greatly appreciated .

[@cbrrebates]

Have the same motor. How did debris got into it?

[@-CCdude]

Hey mountain bike I have this exact mower you should show how the change out the needle seat. I rebuild mine still runs like dodo did you find out why it was still running ruff????????

[@scottmanzie5644]

Hi mountainbikekayak, I have this exact make and model. Could you please give me a link were I may purchase both of the governor springs? Thanks in advance!

[@aaronslaughter917]

What Length is the throttle connection cable to the handle?

[@mikehoward1358]

I have the c same mower. The part where you said you just need to disconnect the linkage to pull carb and tank off. Is that difficult to disconnect? It looks fragile like it would be easy to mess up?

[@BigDOlsen]

How much does that mower cost

[@RmanEagle54]

what was the carburetor kit that you used ?

[@fleadoggreen9062]

Same !! Need part numbers please

[@dingodave9160]

Great video, THANKS!

[@rockyreynolds4027]

I have this same mover and it dies as soon as the choke opens up any idea what is wrong

[@EllisMowersandmore]

I'm thinking what Pete is, hopefully it's just a partially sheared flywheel key. Seems like the 675 series are the worst at shearing them for some reason. They by far are the ones I have to replace them in the most. But good job on getting it running again!

[@mountainbikekayak]

Hello Ellis Mowers thanks again for viewing! Yes that was a great suggestion Pete provided as well and I will do that remove the flywheel I keep a bunch of those keys and see what it looks like. Can't see any real damage on the blade but it does not take much if it had an abrupt stop. Plan to also remove the blade and check the balance on it and get a closer look to see to see if it needs sharpening or has hit anything. It cleaned up like a new one hopefully to give an update soon.

[@oscarchavez8414]

The video help a lot to clean mine thnx alot!!! It's running like new

[@mountainbikekayak]

Hello Oscar Chavez thanks for viewing! Great job getting it back running again glad this could help!

[@aBlurryCat]

How tight should the bolts be when I put the carb back?

[@baldeagle242]

Thanks for sharing. 👍

[@chefkdowg]

They never gap plugs new, I gap mine to .028. There's something still in the carb. Or run a bit of sea foam through it, maybe adjust the govener spring.

[@michaeljude1965]

I was going to suggest a seat replacement too but there are some smart cookies already chiming in on that. I have a tecumseh doing the same, that I need to order some seats for, thanks for the order reminder :)

[@mountainbikekayak]

Hello Michael yes get great help and suggestions from yourself and others off KZbin. Started back with the carburetor again and did replace that little rubber seat and that corrected the problem! Will post the video of that its running like it should now. If you have not already bought your part you can find at least on Ebay new aftermarket Tecumseh carburetors for under $10, complete which includes the primer bulb. Tried one of these last year on a Toro and it ran great afterwards, thanks for all your suggestions!

[@veldo2218]

Where can I possibly purchased the kit, I have similar set up of lawn mower they are 675ex Briggs and Stratton 190cc

[@paulg444]

fantastic video... but did you ever fine tune and make it run better. Im guessing the next move is a minor valve adjustment ?

[@rossdmcc]

I find it interesting you say size of the screws by the hex head size. I've been a machinist for 40+ years and it is weird to quote size as the hex head size. I am looking as to why my one year old DR string trimmer won't start. This is the beginning of the second season and it sucks. This one wasn't DONE RIGHT which is what DR stands for. I paid $500 for this thing and it barely made one season!

[@mountainbikekayak]

Hello Ross what a great job you have being a machinist! Wow you bought what is suppose to be the best the DR anything machines! It seems the problems if this is a 2 cycle is it could be ethanol gas it just doesn't sit very well for extended periods of time versus Non ethanol. Not sure if that is what occurred in your fairly new DR Trimmer but just the few I have worked on the gaskets get brittle and dried gas clogged it up. My neighbor had a fairly new Mantis Tiller and we ended up putting a new carburetor on it a few years ago, it was just ruined. Since then been using these pre mix cans with non ethanol gas and it has not failed to start again. See if it will start with any carburetor cleaner sprayed in the intake/filter area. If it does attempt it certainly is a fuel/fuel filter problem. Those are nice machines its shame that happen.

[@angrygamingdad4378]

Where did you find the carb kit? I have a tb210 12a-a25u711 and can't seem to find carb parts at all. It looks identical to the one in this video. I also need the auto choke spring.

[@ron3393]

Thank you.

[@Dontcaredontcaredontcare]

I just put a new air filter, spark plug and new oil and gas but I can't get it to start.. maybe I didn't clean the carborator properly. Idk

[@Dontcaredontcaredontcare]

Yeah I definitely didn't

[@fleadoggreen9062]

zach meals if you take off the air filter You can take off the bottom bolt on the carb float bowl! That little gold bolt has little holes that get clogged, I use a guitar string to clean out those little holes

[@Pooroljc]

NGK Plug and some sea foam will make a difference.

[@kattor4]

That looks just like my mom mower. Im trying to find out about the carb. It has the numbers 2262 and 4098 on it, but; that is all I can see. Do you happen to know the brand of your carb. ?

[@BrightStar3862]

I've got almost the same mover - mine is push. Similarly, it will not start. Should I clean the carb, as well? Thanks, TED

[@samaribell5480]

Hi, I just followed this video and my mower still won’t start. What could be the issue?

[@mountainbikekayak]

Hello Samari Bell thanks for viewing! Ok is any fuel leaking anywhere after you reassembled the carburetor? Also make sure you are indeed getting spark from the engine out of the spark plug. Tell me more about what symptoms you had before and that may help to understand where to trouble shoot. Thanks!

[@kyboy5]

I have the same mower for free, strong engine but it's ready for a little service job

[@sergeymagel8715]

*Awesome & Tasty View. Happy Weekend.*

[@christophershanepowell1319]

I have a Brute , Briggs & Stratton 6.75 EX Ready Start 22' Front wheel Drive lawn mower . I can't get it to start . " It backfires" I put new spark plug in it and a new air filter. Has anybody had this happen to them , if so can you tell me how to fix it.

[@mountainbikekayak]

Hello Shane thanks for viewing! A couple of things to check when you pull the rope does it have or feel like it has compression or resistance. Also did you hit anything recently in the yard with it and then it wouldn't start. It almost sounds like a valve is partially stuck on it backfiring and or that flywheel key has been partially sheered throwing the timing off. If this is the first start of the year and being that is a 6.75 engine I presume it close to being 10 years old. Just reply back and see if we can diagnose what it may be and how to correct it. I got videos on replacing the flywheel key as well as freeing up a partially stuck valve.

[@DavidisDawei]

Amazing how the tiniest thing can shut down an entire system... how much time did it take to take everything apart and re-assemble?

[@mountainbikekayak]

Hello David! It certainly doesn't take much to plug these up just some old dried gas. It took about 30 minutes these are easy to do and this one was actually pretty clean. Are you still traveling in China now.

[@DavidisDawei]

Hi Cliff I'm surprised the degreasers didn't work I'm back in NH - trying to get things organized so I can leave again!

[@rossdmcc]

By the way good job on making that thing run. You say they gave it to you?

[@mountainbikekayak]

Hello Ross thanks for viewing yes got it free off our local Craigslist advertisement. It just needed the carburetor to be cleaned and I also had a follow-up video the little small rubber needle seat had to be replaced. That got it back running smoothly again!

[@jasminedavis5672]

Hey can you tell me where to order hat carb kit from? None of my local hardware stores have it and I’m having a hard time finding it online! Thanks for this video, I’ve never worked on an engine before but my mom gave me her mower that hadn’t been used in 2-3 years so this was necessary.

[@mountainbikekayak]

Hello Jasmine thanks for viewing! It would be Part # 498260 you can find these on Amazon and or Ebay and the price ranges from $5.00 to $10.00. The kit comes with gaskets, float needle, float pin, seat (for where the needle sits) and may have other parts not really needed. Its almost as cheap to buy a new after market carburetor if your engine is like this one its a autochoke engine (no primer bulb) it would take part # 799866. You can also gets those on Amazon or Ebay from $7.00 to $12.00. Much easier to just replace not as messy either, have used a number of these and they work great. Have several videos installing new carburetors as well. Let me know if you have any more questions Jasmine!

[@jasminedavis5672]

mountainbikekayak wow thank you for your speedy response! Very helpful!

[@berardia4]

That mower is starving for fuel. when you put the float on it wasn't moving down all the way and won't fill the bowl with enough fuel. most likely a swollen seat in the carb. My tip on the oil. I keep some used oil on hand that's not in bad condition and use it for oil flushes on these type engines when they come by. Don't like to waste new oil.

[@mountainbikekayak]

Hello al b thanks for viewing! And your right that fixed it! I did not have a rubber seat in that carburetor kit I had already used it for another lawn mower and just went for the cleaning. That did not work just received an order for 10 seats today. After replacing that seat it runs like a new one no more engine miss, what a difference! I will post a follow up video on it. Great idea on the oil I do keep used motor oil for recycling but could always save it just to refill a unknown engine. Changed the oil in this again ran for quite a while it looks pretty clean so got most of that old sludge out.

[@berardia4]

great glad its working better. always like your mower videos.

[@peterkay7458]

Al I am amazed you figured it out just watching the video....beyond impressed

[@Herfortz]

It sound's okay to me cliff ..... At least it run's.

[@edgu71eg]

So did you use the kit or not?

[@mountainbikekayak]

Hello edgu71eg thanks for viewing! I did not use that kit on this first carburetor cleaning or any parts on this video. The follow up video I took apart the carburetor again and replaced the small rubber seat the needle sits in. That corrected the miss within that engine. They had attempted to get it running again with a new spark plug but it was fuel problem, the spark plug was not gapped correctly they also had put in. It was pretty much neglected the oil was never changed, so changed it and after replacing the rubber needle seat it was running great again. Attached the link here for the 2nd video replacing that seat and how it ran afterwards:: kzbin.info/www/bejne/Z16ol4mwlMyDbtE

[@Dom59878]

I have the same lawn mower that wont start...What's the carburetor kit part number and from where can I get it. Thanks.

[@mountainbikekayak]

Hello Domenico thanks for viewing! This is the Part # 498260 you can find these on Amazon and or Ebay. Most are aftermarket showing that part # and they are pretty generic they may have parts not needed for this carburetor. I noticed on Ebay a seller has the OEM Briggs and Stratton kit for $8.95 with free shipping. I have also bought after market complete replacement carburetors if your engine is a autochoke like this one (no primer bulb) its part # 799866. Have had really good luck with those I see one on Ebay for $8.99 free shipping brand new for an autochoke can't beat that price!

[@Dom59878]

Yes it is an auto-choke, the mower model number is 12A-466M011. Seen that the price is almost the same what would you advise, get the rebuilding kit or a new carburetor.

[@m.t.426]

Can't hear you

[@matts7975]

Someone obviously tinkled into the gas tank. The color, the smell. Therein lies the problem.

[@petefroud5308]

Perhaps the timing is out a touch.

[@mountainbikekayak]

Hello Pete thanks for viewing and great idea. That is for sure one thing to check is the flywheel key. They may have hit something in the yard and its partially sheared just ran it that way and eventually bought a new lawn mower. Its just not quite right hopefully the engine is not damaged the dipstick just registered no oil when first checking it.

[@petefroud5308]

Hi if it is out not by much . Its just that chuffing from the muffler seems to point to the timing . From your video the deck is not shaking to bad ,so the crank should be ok . Hopefully no damage in the engine

[@kaalind475]

wait i thought thats what a mower sounded like when it was good

[@dylangleason7213]

buy a new carburetor that should fix it.

[@mountainbikekayak]

Hello Dylan thanks for viewing going to just look at the flywheel key to make sure it has not been nicked and if not revisit the carburetor. Have had really good luck with the after market ones you can buy they are under $11.00. Just used the last new auto choke one recently, this lawn mower is so nice it would be worth while to order one if I can not get this resolved.
