Awesome video. My brother brought me a 46" mtd mower with a ELS 656 22 HP briggs and I put new plugs and checked for spark and good. I then took fuel line off and cranked and it was spitting fuel so good fuel pump. I took the little brass plate with 3 screws holding it on off and sprayed throttle body cleaner in there and cranked and it starts but surges horrible and smokes. When I try starting it back it won't so it must be the carb. Mower sit a couple of years and worked fine when parked. This video helps show me what I need to check it's a little different than mine but I think carb is the same. Thanks for posting.
You’re welcome, good luck!👍🍀
I had the same exact warping on the manifold. If you hadn't made this video, I probably wouldn't have known to look for it and I wouldn't have known how to fix it. Thanks, buddy!
You bet!
The tool for those threaded rods is a 4mm socket.
Thank you I cringe when I see pliers used to remove things LOL
Thank you for creating this!
Man...I'm glad I found this video. Problems with my Briggs dying after about 25 minutes. Figured it was the carb - put a new aftermarket on there. Immediately noticed the bow or gap on the manifold. Problem was worse afterwards (old carb fit cleaner than new). Was driving me craze - found this and confirmed I had a problem. Going to use some Permatex HT gasket maker and hopefully it fixes the problem. Thanks for making this video.
Hope it helps.👍
I wonder if that warped intake would cause me to have my choke perfectly set at a certain setting so it will run on two cylinders instead of one? My choke is very finicky and has to be at a precise setting for it to run two cylinders.
Good information. Could be a 7 minute video.
Fuel tank vent is plugged and causing vacuum in the tank will cause your sputtering issue after 20-45 min depending on the size of tank.
was hoping you would have shown the two linkage rods, mine is apart and forgot to mark the hole, three weeks to get the carb, next time i will take pictures
Thanks for the how to on changing out that carb. I got a Craftsman with that B&S 26 HP v-twin engine. Ordered a aftermarket carb off Amazon. Your video and advice will help guide me through the process.
You’re welcome! Good Luck.👍
Man.. do you by chance have a more detailed video/picture/instructions or anything showing how the linkages go back on. I took mine off over a month ago to clean the carb bc it wouldn't start and I can't remember where they all go back it's been driving me nuts lol. Been push mowing the whole yard haha
I'm used to working on Kohler and Kawasaki engines, so I couldn't believe the size of this monstrosity 😂.
Could be the gas cap. I had that happen on a lt2000. The pin holes in the gas cap got clogged.
same here. hundreds of dollars later, it was the damn cap
Heat gun and you can take the “bow” out of that plastic manifold some. Just takes patience and time
THANK YOU! Without this video (which I watched probably 10 times!) I never would have had the confidence to try to fix my own mower. My older Husqy mower would run for about 15 mins and die. It was so aggravating. Long story short, after tearing it down and pulling off the carb and intake, I ran into the same problem with the warped intake. I added a bunch of gaskets, and still needed the RTV. I sealed that entire frickin intake with rtv and CA glue to fix all of the leaks. I ended up replacing the carb, and a breather tube as well. But I just ran my machine for 1.5 hours straight and it seems to be good so far. Thanks for showing me how to actually fix something!
Great job! It sure is a good feeling when you are able to fix something! I’m glad my video helped you!🙂
I wonder if the plastic manifold was the issue the whole time?
I really need some help with the linkage! I just can’t figure mine out. It’s a hasqvarna rz46i and replaced the fuel pump and carburetor but not sure where pins go :(
Thanks for the video. I have been having issues at start up. it will start with carb. cleaner and stay running but it will only crank without it. I have fuel and spark. I am thinking it could be the auto choke?? it is a 27HP Briggs and Stratton on a Simplicity Broadmoor.
I am wondering if you might have some water in the fuel. Especially if the tank is above the carb, the water will settle in the carb bowl. It could also be the auto choke like you say. Could also be a vacuum leak. Check the vacuum tube going from the valve cover to the pump for cracks. If it is cracked the fuel pump won’t work correctly. That’s a very common issue on these engines.👍
After cleaning everything and adjusting the throttle cable, I noticed a crack in the vacuum hose from the valve cover to the fuel pump. I temporarily put electrical tape on the cracked hose and that solved the starting problem. Something simple to look for.
@@scottwidrick1835great to hear! Those hoses rot out every couple of years. Good job!👍
Hello could you give me the link to which aftermarket carburetor you used?
I use only Hipi carb period
4 mm socket that fits the bolts
Great video, very helpful. Thanks!
Glad it helped!😁
What engine is that? I have a Briggs V-Twin 407777 and it does not have the metal "shim", but the aftermarket carb came with it. Should I leave it out or install it? BTW, a 4mm socket will fit the outside Torx bolts.
I don’t remember the number and the customer had the mower back now. From what I understand the shim wasn’t put on earlier engines and was added later on to help with fuel issues.👍
What carb did you buy? It have the same one I need to replace
@@vietphan470 to be honest I can’t remember but I think I bought it on eBay. I look up the engine model number on google and find the parts diagram at any small engine parts store, Then you can search that carb number where ever you’d like to purchase one. 👍
Thanks you just helped me install a carburetor 🎉
Glad to hear!😁
I have 22 hp B&S carburetor that has been discontinued. V -twin Nikki . Found a OEM rebuild kit for 75.00 . Should I buy an after market brand ? If so what type
A, T7
Thanks for your video Man. I'm fixing to do this on mine after replacing the fuel pump, that lil hose and checking the flywheel key which seemed to be fine. Hopefully this fix My problem... 👋🏻
Good luck!😁
Just fyi a 4mm socket will work on those carb bolts
I have a surge when in low idle, will changing the carb fix that?
Generally surging is a fuel issue.👍
Rebuild the Carb. There is a number printed on side of carb. Amazon will send a kit tomorrow. Note: There is lots of extra parts in Kit. you may have extra parts. That's normal. The valve cover has the engine model number. That may help you also. Usually surging is dirty jets. Engine is starving for gas. I have fixed this issue many times.
Excellent video
Thank you very much!
Hi, what is the difference between intek v twins 18 20 and 22 hp . Can you make 22 from 18 ?? Thanks
To be honest I have never tried to do this but as a general rule, the higher the horsepower the larger the displacement inside the cylinders. I am sure it is possible but I’m not sure at what cost, it may be more cost effective to buy a larger motor instead of build it for that little bit of power. It could be a simple cylinder bore with new pistons and rings. Also as a general rule a smaller displacement engine can usually take higher heat for a longer period of time so by boring out the cylinder there is less metal and it can be more prone to failure. If you try this please let me know how it turns out. Good question.👍
@@beesprojects2692 Hi Thanks for reply, i think they all have the same displacement. I was wondering if the difference only in the carb ?
@@AKGaragezz a quick search for displacement on an 18 hp showed 540cc and a 22 hp showed 724cc. I guess I just assumed that cubic centimeters and displacement was the same thing. I am almost certain that the carburetor would have larger jets to feed more fuel to the larger hp engine. I have drilled those jets out before with good luck but it was on a high hour engine that needed the extra fuel to run right.
@@AKGaragezz yes its the jet size which can be swapped out with old carb to replacement carb
There different sizes and have to go back on same side of carb
Be careful not to put on wrong side of carb
I smell gas when parked. It spits gas out exhaust when first starting. Following your directions when I removed the fuel hose on top of carb gas ran out of rubber hose and continues to do so unless I keep hose elevated. Is this normal? Maybe fuel pump issue? Thanks
If the level of gas in the gas tank is higher than the end of the hose, gas will run out. Sounds like you also have a flooding issue. I would check and make sure your float is good and your fuel shut off solenoid is working properly.
I swapped the carb on my B&S 20 hp v-twin engine following your info video and I appreciate what you shared but, when I finally got it started , it runs wide open while I am trying to adjust the throttle. The throttle cable moves a silver plate under the carb but it does nothing. What can I do to fix this problem?
Sounds like you have an issue with the governor, I’d check to make sure that all of the linkages are put back on the way they came off or that you’re not missing one. I’ve done this a couple of times when I removed and installed a carb just getting in a hurry. That’s where I would look, good luck. 🍀
Exact problem I was having. The plastic was warped in the same spot. Gasket maker seems to have fixed it. Thanks.
Fuel pump hose to valve cover number ????
596163 is the number I used
Yep, the linkage on the left as you look at it from the front.... having a hell of a time getting it back on...still fighting though. Also had the warpage as well but the little shim and extra gasket seems to have worked so far. Thanks gor the video
Does the 22hp have under carb have two springs
Excellent video. Thanks
Liked, Sub'd, Belled.
Make sure and install new seals every time on plastic manifold or it will leak for sure
I got a husqvarna 22v46 riding mower it was surging so I removed the carburetor to clean it after I put it all back together it now starts with the rpms racing easily hitting 5k rpm
Linkage issue maybe? Maybe the governor arm loosened and slipped? 🤷🏻♂️that’s all I can think of that would make it over rev. I’d check anything to do with the governor.
I have had more issues with this engine than anything I’ve ever worked on. When I tore into it there was mismatched gaskets, no gasket on one of the intake sides. Just garbage.
Good Feller there.
I Need to do the same for my Briggs, The problem is that my Old Carb Is Not the same as the ones' you have in this video. Mine is Engine 44R877 Type 0001G1 CODE 150128YG I sent you a Picture of it
I have the same issue - missing a linkage aperture in all the new replacement carbs for a "air vane" - still trying to figure it out.
5 m socket for studs
These are my favorite engine to rebuild and there really dependable plus they take a over haul really good and last a long time
I hate the plastic manifold and sometimes you have to grind a little for replacement carb to clear manifold
i agree, the governer linkage hangs up on the side of the manifold.
Thanks for the detailed help, especially showing the shim placement on the carburetor between the two gaskets. A 1/4in socket also works on the four torx head screws,
Excellent. Liked gasket install sequence AND, point out warped manifold ... appreciate posting. I believe a 12 point socket can be used to remove the four bolts... vs special torx socket set
Really appreciate you! Hubby and I have spent 4 days trying to find out where one of the springs attaches correctly. Your video was the only one that showed enough detail. Turns out, our manifold is also warped! Thank you so much for taking your time to help us💞
So glad it helped!😊
Am I the only person who noticed he is spilling gasoline in a workshop heated by an open wood fire?
It’s not an open wood fire, the wood stove is enclosed. There was extremely little if any danger here. I can appreciate your concern though.
Yes.
3 minutes in and we are gonna finally hear about this mower.
Sorry for the inconvenience, I hope you got something out of the video.
Fuel tank vent plugged will cause sputtering.
I have a YTH22V46 and it has a completely different, smaller carb with a different manifold and intake. Have you seen this before? Can't find any info on it. Already ordered a supposed replacement and it doesn't fit of course. Thanks!
Yes, I believe that there were a few different variations of those engines with different intakes and carbs. The mower model number probably won’t get what you want. Try to find the model number of the engine and use that when ordering parts.
It's a single barrel carb. I got lucky and found the part number on a forum. (595216) in case you ever run into that. @@beesprojects2692 Thanks
