I think this has been the best and most comprehensive video I've seen so far concerning how to work on small engine carburetors. Thank you so much for making this video. It's helped me a lot!
Man... I searched and searched to find the exact repair video to fix my BlackMax EXI 725 for days... and finally found yours...THANK YOU SO MUCH FOR CREATING THIS VIDEO BROTHER 👍🏾
Hand's down, ONE OF, IF NOT THE BEST technical 'how to' videos I have ever seen! And I've seen A LOT. Everything is well described, well explained, reasons for everything given, well videoed and edited. This guy is not only knows his stuff, but is articulate as well! Thanks for doing such a fantastic job!
@@EliminatorPerformance I couldn't agree more about this detailed instruction video being thorough & complete. Great job and thank you! However, once I finished cleaning the parts well & dried I had an issue while re-assembling the carburetor, specifically the small bowl drain plug & that small O - Ring that seats inside the bowl drain plug. I found out the hard way how it can get pinched & rip when turning the plug with the hex tool. I used 3in1 Oil on the O - Ring, but it was a little stretched/worn & didn't want to sink into the groove when attempting the 1/4 turn required for it to seal properly & the little tabs on the plug that grip the tabs of the inside end of the hole cracked, rendering the plug itself useless as well as it's o-ring. The rest of the carburator went back together like new with no problem sealing the bowl, the jets cartridge, floater, needle, etc... The only issue is the plug & o-ring. I see replacement #'s for the entire Carburetor or Jet cartridge that you've left here in the description but can I just get the bowl plug & small o-ring replaced, as opposed to replacing the entire Carburetor & do you have the parts #'s for only that so that I can order them, please? I would appreciate it greatly!!! Again your videos are easily the best on TH-cam, hands down. Please reply
You are THE BEST teacher! I watched several videos on B&S carb rebuilds and this one is the best by far! Thank you, my lawnmower is running like new!! :-D
I have the exact same Yard Works lawnmower with the Briggs and Stratton engine that is featured in your video. The mower would start and then die. I googled for info on that model with a plastic carburetor and viewed your video. You saved me a repair bill and the possibility of having to purchase a new mower. Thank you.
Very informative. Step by small step. Perfect for someone like myself who's never worked on a carburetor before. Excellent approach and instruction. Thanks.
Excellent video -- loaded with info, concise, and excellent views of the parts. Today I started a carb clean on my 725exi and stopped to see if I could find some info on TH-cam. I'm sure glad I found your video - it has saved me from making a mistake or two. Thanks!
Very well done. Clear and concise. I have this exact engine on a power washer, only one year old. Couldn’t keep it running. Decided to follow your carb cleanup - gel fuel was exactly where you mentioned. Reassembled , started first pull. Thank you for the video.
I’d swap this out with a metal carburetor if I had one of these. This is definitely a ridiculous design flaw to have a plastic carburetor and not a metal one!
Thanks for the video, i just removed the carburator and cleaned it with brake cleaner . It was full with oil. I missed your video so i didnt cleaned the jets in distributor. Will do it again. Thanks to your instructions. Just a message to youtubers, in my case the previos owner had about 1/2 a liter of extra oil that caused to run into the carburater when placed in shed upright.
You saved me from buying a new mower man! I followed your video step by step and after reassembly it started on the first pull! Great instructive video! I have subscribed and liked tour channel!
Great video! One thing to be wary of when using compressed air to clean the white main jet cassette is that it is possible to dislodge the other brass jet insert. Not the one that sits in the fuel in the float bowl but the other one. This happened to me but luckily I saw it fly out and found it!
Great video, however I wouldn't recommend using a screwdriver to remove the main jet! It comes out easily wiggling with a pair of pliers. Also, the main jet comes apart into 2 pieces for a more thorough cleaning.
This may be the best 'how-to' repair video I've seen. Solid, friendly advice with a good pace, excellent close-ups, and simple steps. It includes re-assembly details and gotchas that others often gloss over. I followed step-by-step, pausing the video as I went. The only issue in my repair was due to my ignorance. I sent the lawnmower blade out for sharpening and tried to start the mower without it. OUCH! The kickback from the pull cord almost yanked my hand off my arm at the wrist! Apparently, this motor uses the blade as flywheel weight and kicks back with a vengeance without it. Thanks again for the quality video!
I always try to blow/wash off the engine before working on it. Great Fix. I run a bunch of short metal screws with hex heads into worn tread on drive wheel.
Just fix my neighbor's lawnmower equipped with plastic carburetor through 3 videos l viewed today . Your's are the most informative, thanks However, do simplify some procedures, since the interiors are pretty clean after opening it up, just pop the cartridge up ( using those sewing package needles and tool from Dollar Store) clear slightly enlarge the main jet, mouth blow to ensure all holes are unplug ... Reinstall accordingly ! One pull started and stay on repeatedly, Self satisfaction 😅hank
It’s always best to clean the crud off of the mower before you start trying to fix it. I’ll be working on my son’s mower later today. It has that carb on it.
I'm a EETC certified mechanic and I want everyone to know not to leave any gas station type fuel in their machinery for more than 6 weeks. If you can get Aspen fuel it's all you need and I will stand by it. Run the fuel tank completely dry and put in some Aspen fuel. Start the engine for a minute and set it off the side till next year. Aspen fuel is good in the tank for three years and good in the in the unopened bottle for five years. It will stop your carburetor problems with this and it also burns cleaner then any other fuel. I will stand behind this method over anything else. Standard fuel from the pump is the biggest problem. Look up Aspen fuel and you will see.
I had to quit using Aspen fuel because the fumes burned my eyes. Also had other guys who couldn't race go carts using Aspen because of how it negatively affected drivers behind anyone who was running Aspen. Not sure why, but we've switched to Kinetix engineered, ethanol free fuel and it works great. Gulf Pro also sponsored us but their products were far to expensive.
@@EliminatorPerformance I only recommend it for storage. I don't recommend to use it constantly. I fully understand what you mean. That is why we only use it to store the machine when not in use. I will have to look that fuel up. I'm in the Pacific northwest and I haven't heard of that brand. Thank you for your information I'm greatful for that.
@@Rabid_Badger_racing I get Kinetix through Power Source Canada here in Ontario, which is the Power Distributor for Briggs and Stratton parts. I believe the main distributor of Aspen got in an argument with someone and it's harder to get through various suppliers, as I know Theo Turgen and ESF Direct stopped selling it as well. The Gulf Pro Fuels is available only through a company called Small Engine Service, and their costs were unfortunately too much. Because I'm a dealer through Power Source, I get free shipping on orders of $350 Canadian, so I usually add a case or 2 of fuel (50:1 or straight) and use the free shipping on that order as an additional cost savings. We do not use TruFuel anymore as we had issues with their fuel, mainly because there was never a date code, so you could be buying 5+ year old fuel
@@EliminatorPerformance I learned about trufuel in school and I don't like it either. I found it was a waste of time. That is why I started researching all synthetic fuels. Me biggest concern was to help customers who were bring in machines constantly because of old fuel from clogging up carburetors.
Absolutely the information I needed and then some. Great video, well presented with no wasted bull-pucky. Thanks for the parts info also. Now back to the mower!
Excellent video, my mower was "surging", I didn't find anything obvious like the chunks in the video but after cleaning the carburetor, cleaning the tank and using new non-ethanol gas the mower works great, thanks.
Very detailed, excellent. Thanks for showing how to get the top off. You can buy these carbs. for $10. The same carb has three #: 596505 or 597327 or 594058
I have never used my altra sonic cleaner on a plastic carb. I have used it on aluminum carbs with Simple Green Pro HD concentrate. What concentrate are you using?? By the way you do very good video's!!
So you need to find the model number of the engine, not the mower. Look on the engine, you should see a number somewhere from Briggs and Stratton. Some new ones even have a qr code you can scan. Take that number and google it with parts diagram after, you will then find the parts listing. Choose carburetor diagram and then you can get the proper needle valve part number by selecting the part on the diagram. Then order it from anywhere you can
What solution do you use in the ultrasonic cleaner? I fill mine with water then put gas in a Ziploc bag with small carb parts. Sounds crazy but I got the idea from Steve's small engine repair or something like that. I don't use the ultrasonic much though.
I try to keep my lawnmower in top condition and store it over the winter by running it dry, but even then it still requires a manual carb clean before the first mow of the season with fresh fuel. Thanks for the tips and advice
Try to buy a can of engineered fuel, like VP or Kinetix, even Aspen fuel, run mower dry, add half a can, start and run for a minute and then shut off and store. It'll start next year almost guaranteed!
I watched your video and had the carb cleaned and mower running in about a half hour! It was blocked in one of the tubes. Thanks for taking the time to post your vids.
Thank you for the very good description of what I need to do to fix the engine on my step-daughter's lawnmower. I am a true newbie when it comes to fixing mechanical things, but you did such a fine job of telling and showing me what to do that I feel confident that I can do the job.
Hey Champ - I did this to my friends slighly smaller 5.5 140cc Briggs and Stratton - didn't work. IF THE SPARK PLUG IS WET -- Do you think its the ignition Coil ??? Please Please resopnd.
It's possible, remove the plug and pull it over a few times to dry out the cylinder. Put the plug back in, remove air filter and spray a small squirt of starter fluid in the intake. If you pull it and it doesn't fire, you likely have no spark.
EXCELLENT video! Thanks very much for posting. I have a Craftsman mower with one of these cranky plastic carbs. Your video is just what I needed to fix my mower and put it back into action.
Hey Tough Guy - You are a Champion of the People. You Saved me $75 bucks and gave me the Satisfaction of Accomplishment. It Worked - My Mower Started on the first pull..... Twice. Wanted to make sure it wasn't a Fluke. Thank You.
Excellent instructions and easy to follow your detailed approach. Only issue I had was reinstalling the main jet housing. Could not get it pressed in. Looked in the bowl and saw a sleeve was blocking the center port. With a small piece of wire I pushed it out of the port and everything snapped into position. Thanks for your excellent work.
Yes I forgot to mention that part, if you bump the carburetor or move it at a certain angle, the tube that it presses into can shift. Thanks for watching!
Excellent video describing cleaning B&S plastic carburetor. I successfully cleaned one on a B&S 675, but this video showed more detail by further disassembled the jet assembly.
Nice video but I drill out the main jet with a # 72 drill bit .025 works great , starts first pull ,,,,even the ones without the auto choke . I'm a 74 year old machinist and I'm like you " Old School "
I could not ask for a more complete tutorial. The last time this happened, after taking out the carb, I just bought another for 20 bucks. They probably cost a lot more now. I also installed a fuel filter and fuel cut off valve back then, so I won't need to pinch off the line. Thanks to you I am going to clean the carb this time and I appreciate your help and well done on its production. The metal carbs on the old briggs seemed to last for more than a decade without fouling.
Hey man, just wanted to add that you do a great job with your videos- have helped me out on several occasions- always concise and very helpful. Big thanks from a Georgia boy
My Troy Built mower with the same Briggs and Stratton engine/carburetor wouldn't start after sitting all winter. I've never messed with small engines or carburetors, but I found this video and it seemed easy enough. Followed it exactly, took apart the carb, cleaned up the fuel tank and fuel line - which is where the problem was. My screen at the bottom of the fuel tank was gunked up with old gas and when filled with water nothing flowed out. Anyways, learned a lot from this video and it solved my problem and saved me a bunch of money too. Thanks!
Excellent vid bro...the only thing I would suggest to everyone is to not use a flat head to pry out that white plastic jet as it can damage the plastic around it and the seal as stated. You can push from the inside of the cab where the distribution tube comes up, then u can gently remove from the under..that hole where you push that tube down must be lined up before re installation... Lovely detailed vid bro!
I have a DR trimmer with a Briggs & Stratton 6.75 engine. Couldn’t get it to start. It would fire with starting fluid and then stop so I guessed I had a fuel problem. At 82 I wasn’t sure I was up to tackling a carburetor clean out never having ventured inside an engine before but watching your excellent video convinced me to give it a try. I watched a dozen videos and must tell you yours is absolutely the clearest step by step complete explanation with excellent video! You even showed how to remove the engine cover which none of the other videos thought to include. I was about ready to break it off after removing the 2 bolts. I knew you were a premier TH-cam instructor when you took the time to list the part number for the o-ring around the top of the fuel jets assembly which might become damaged during take apart. The gold at the end of the rainbow was when my B & S started and ran perfectly on the first pull. I appreciate the time you take to make such an excellent, detailed how-to video. Bob Mc Bride in Maine
Great video, I reassembled and started it up right away! Only one issue though, fuel ends up coming out of air filter after use, not sure what’s wrong?
I drilled out the main jet since it was clogged so bad I could not get a bread bag wire thru. Since then the engine has dropped RPM's too about 2000. It also is blowing white smoke thru the muffler. I tried adjusting the arm to increase the RPM's but no significant response. Did I ruin the main jet by opening too much? Let me know your thoughts. Thank you Eliminator for your expertise.
This video was frickin fantastic I like the way you somehow was able to follow your work and you did not sit and talk about b.s. I noticed a lot of people make videos just like to ramble and here themselves talk, kind of like when we were younger and called a radio station to hear ourselves the DJ would always tells us to turn ur radio down !! Anyway I will gladly watch any video that you produce I enjoyed listening to someone that knew what they were doing and not just winging it! Thank you sir.
Thanks, most people tell you just to replace the carburetor if it's plastic, who knew it's so simple to clean easier than the metal ones I think, I have 2 carbs like this, cleaned both after watching this no problem.
This is the best DIY video that I have used. The steps were laid out in a logical manner. The tips given were very useful. My mower runs like new. Thank you.
Hey man great tutorial! I have a power washer with this engine. I was worried I'd break the main jet distribution assembly and your video helped me confidently remove it from the plastic housing. I may have gotten it without the vid, but I also may have broken it cursing the whole time hahaha. I fixed my engine using only some carb cleaner spraying the jets which were plugged due to E10 gas left over winter. I ended up watching the entire video. Just want to let you know that I like your commentary and editing. This is the first video of yours I've watched. You have a way of including all the pertinent detail that's condensed yet understandable. You're a great mentor thanks!
Best video on how to clean the carburetor on the net. Managed to get a smooth running engine after following your extremely simple and clear instructions. Thank you and well done!
Rebuild based on the first two videos didn't work. This one was much more thorough. I rebuilt based on the steps here and she started on the first pull. Great video! Thank you!
Nice tip on trimming the choke lever! Many seem to hate these plastic carbs, but I love 'em. Consider the simplicity, ease of service, entire jet system pops right out, and NO CORROSION, EVER! Depending on the equipment, you can even do the clean and not even remove it from the engine. Excellent vid as always.
Thanks for the comment about being able to remove the jet system assembly without actually removing the carburetor. That is specifically what I was wondering about. So I thank you very much for that.
I think this has been the best and most comprehensive video I've seen so far concerning how to work on small engine carburetors. Thank you so much for making this video. It's helped me a lot!

Thanks for the breakdown. “Problematic” brass port on bottom on main injector tree was it!
The only thing I had happen when I slid the pin is the needle valve dropped out from the float assembly, lucky for me I spotted it before it vanished!

My Troy Built mower with the same Briggs and Stratton engine/carburetor wouldn't start after sitting all winter. I've never messed with small engines or carburetors, but I found this video and it seemed easy enough. Followed it exactly, took apart the carb, cleaned up the fuel tank and fuel line - which is where the problem was. My screen at the bottom of the fuel tank was gunked up with old gas and when filled with water nothing flowed out. Anyways, learned a lot from this video and it solved my problem and saved me a bunch of money too. Thanks!
Excellent vid bro...the only thing I would suggest to everyone is to not use a flat head to pry out that white plastic jet as it can damage the plastic around it and the seal as stated. You can push from the inside of the cab where the distribution tube comes up, then u can gently remove from the under..that hole where you push that tube down must be lined up before re installation...
Lovely detailed vid bro!
This is very thorough, really greatly appreciated!
I have a DR trimmer with a Briggs & Stratton 6.75 engine. Couldn’t get it to start. It would fire with starting fluid and then stop so I guessed I had a fuel problem. At 82 I wasn’t sure I was up to tackling a carburetor clean out never having ventured inside an engine before but watching your excellent video convinced me to give it a try. I watched a dozen videos and must tell you yours is absolutely the clearest step by step complete explanation with excellent video! You even showed how to remove the engine cover which none of the other videos thought to include. I was about ready to break it off after removing the 2 bolts. I knew you were a premier TH-cam instructor when you took the time to list the part number for the o-ring around the top of the fuel jets assembly which might become damaged during take apart. The gold at the end of the rainbow was when my B & S started and ran perfectly on the first pull. I appreciate the time you take to make such an excellent, detailed how-to video.

Great video, but The plastic main jet assembly comes apart to reveal a center post with 3 holes which will clog! I removed it with my fingers.
Great video, I reassembled and started it up right away! Only one issue though, fuel ends up coming out of air filter after use, not sure what’s wrong?
Check to make sure the needle valve is sealing properly, and check your oil too, make sure no fuel went into the engine!
I drilled out the main jet since it was clogged so bad I could not get a bread bag wire thru. Since then the engine has dropped RPM's too about 2000. It also is blowing white smoke thru the muffler. I tried adjusting the arm to increase the RPM's but no significant response.
Did I ruin the main jet by opening too much? Let me know your thoughts. Thank you Eliminator for your expertise.
Yes it's possible, you can buy the replacement part 594060 and start fresh
@@EliminatorPerformance Already ordered. Wish me luck. Ty for your quick response.
Well done & thank you, very helpful. The carb. appears to be the same (or at least very similar) as fitted to UK variant B & S 675EXI.
love it, thank you, greatings from Denmark! :)
Thanks for watching, cheers from Ontario Canada!
This video was frickin fantastic I like the way you somehow was able to follow your work and you did not sit and talk about b.s. I noticed a lot of people make videos just like to ramble and here themselves talk, kind of like when we were younger and called a radio station to hear ourselves the DJ would always tells us to turn ur radio down !! Anyway I will gladly watch any video that you produce I enjoyed listening to someone that knew what they were doing and not just winging it! Thank you sir.
Thanks, most people tell you just to replace the carburetor if it's plastic, who knew it's so simple to clean easier than the metal ones I think, I have 2 carbs like this, cleaned both after watching this no problem.
Cool! I had been cleaning them with torch tip cleaners and fresh gas. Thanks man!!! I'm old school.
This is the best DIY video that I have used. The steps were laid out in a logical manner. The tips given were very useful. My mower runs like new. Thank you.
Thanks for watching!
Good job and information.
Great job of detailing the cleaning process! You saved my day, thanks.
Your tutorial is excellent. Keep up the good work brother!
Very good video regarding B&S plastic carburetor. I haven't seen the step-by-step teardown and repair done so clearly anywhere else.
It is alright to use carb cleaner even though these are plastic?
Yes, it's resistant to oil and gas
Hey man great tutorial! I have a power washer with this engine. I was worried I'd break the main jet distribution assembly and your video helped me confidently remove it from the plastic housing. I may have gotten it without the vid, but I also may have broken it cursing the whole time hahaha. I fixed my engine using only some carb cleaner spraying the jets which were plugged due to E10 gas left over winter. I ended up watching the entire video. Just want to let you know that I like your commentary and editing. This is the first video of yours I've watched. You have a way of including all the pertinent detail that's condensed yet understandable. You're a great mentor thanks!
Thanks for watching!
Best video on how to clean the carburetor on the net. Managed to get a smooth running engine after following your extremely simple and clear instructions. Thank you and well done!
Thanks for watching!
Thanks! Followed every step and the mower started up on the first pull. No doubt this saved me a bunch of trial and error.
Really intelligent video. This was super helpful. Thank you!
Thank you for sharing. I can say that your explanation and recording are fiest class. Thank you again.
Thanks for the great video, my BNS mower started right up after sitting for 5 months
Boy, you make it seem so easy!
This helped me a ton. Scored a free 2019 craftsman pressure washer with the same carb and now it’s good to go. Thanks for the detailed video!
Rebuild based on the first two videos didn't work. This one was much more thorough. I rebuilt based on the steps here and she started on the first pull. Great video! Thank you!
Thanks for the great video - fixed my surging mower issue now running like a dream 👍
Nice tip on trimming the choke lever!
Many seem to hate these plastic carbs, but I love 'em. Consider the simplicity, ease of service, entire jet system pops right out, and NO CORROSION, EVER! Depending on the equipment, you can even do the clean and not even remove it from the engine.
Excellent vid as always.
Thanks for watching!
There really easy to remove and clean in ultra sonic cleaner
Thanks for the comment about being able to remove the jet system assembly without actually removing the carburetor. That is specifically what I was wondering about. So I thank you very much for that.
Thank you. I have two mowers that start and won't stay running. I like your video.
