Flooded Crank Case Briggs Fuel Solenoid is NOT the Problem! Needle and Float IS!

- The Solenoid is NOT the culprit as I stated in this video. A faulty Needle and Seat/Float is to blame. The Solenoid is intended to stop backfire conditions by shutting the fuel off when the key is shut off. My apologies for inadvertently misleading anyone. Zip~
This happened to me with my Craftsman but I was lucky to realize what had happened when the mower started smoking like crazy. Got it turned off and totally changed the oil and put a shut off on the fuel line. Just had to remember to turn it on and off before and after use but never had that problem again. Thanks for this good video.
Yep...i ground down that valve...and put a fuel shutoff
This happened to a friends 17 hp inter motor. She said it had a weak battery and it wouldn't start. I jumped it and nothing. I thought it must be the starter. I didn't know if it had a compression release. I took out the plug to see if that would make it easier to turn over. Regrettably she was in front of the mower when I hit the key. She got hit by a stream of gas that musta went out to 12 feet or better. Your video has help tremendously. She said she filled the tank when she put the mower in the shed. The tank was enpty. Thanks again for posting your video. It will no doubt be responsible for saving her motor.
Sorry to hear your friend nearly turned into a human torch. Good thing no one had an open flame. And I'm glad this video helped! So long as she remembers to turn the fuel off before turning the key off, the problem won't happen again. Cheers! Zip~
Great video. my coil went bad on my riding mower. pulled the plug out so I could see if it would spark when I cranked it.
no spark. I ordered a new coil. I am going to put a shut off valve on right now! tell the man that had that mower that you shared his loss for our gain and we all feel real bad for him. what a learning lesson. Thanks again for a great lesson.
Just happened to me on my 13 year old Snapper with a 17HP Briggs. I was “lucky” to have had my started go out and I’ve been pull starting it for a while now. I pulled, Bamm! I almost broke my hand. I kinda guess what the problem was as it was running perfect the last time I ran it a week before. I was able to pull it a little bit and saw some gas come out of the exhaust. I knew then. Put on a new carb, drained the oil, new filter and oil... Lucky. I will put a shut off valve now. Thanks for the video.
Job well done. Almost a decade later nd still saving small engines you the real MVP
Thanks Scrooge! Been at this RUclips thing since 2007! Cheers! Zip~
@@ZippoVarga most welcome
Just added a shutoff to my fuel line. I also had to rebuild my carb. The crankcase was FULL of gas. Thankfully I was lucky this time. Thank you sir!
I'm glad you got it sorted out before damaging the engine Shaun. Cheers! Zip~
One of the Best videos I've seen on saving an expensive engine.
Thank you so much. The Lord bless you on sharing this knowledge.
Started having the same problem on my craftsman mower after 11yrs. Took me a few hours to figure out.Took spark plug out turned motor over a few times an a lot of gas shot out of plug hole .Bought a $3.00 inline fuel shutoff valve at ACE HARDWARE install it an made sure to change oil& filter ,problem solved.I heard the part was expensive,so opted to less an easy fix ,just have to turn valve on or off when needed. Enjoyed your video.........
It's a common issue as these single cylinders age and the easiest band-aid is the fuel shut off for sure. Glad you didn't blow your engine before figuring things out! Cheers! Zip~
I bought a Husqvarna with a Intek 18.5 Briggs on 8/28/2018 and about a week ago, the mower refused to start. I traced the problem down to the fuel shut-off solenoid not opening when 12 v was applied to it. I pulled the solenoid and cut the end off right above the threads and then cut the fuel line and installed a manual fuel shut-off inline. They wanted $86 for a new fuel shut-off solenoid. I paid $6 for the manual shut-off and two clamps. Problem solved and it will also prevent the fuel from leaking past the shut-off solenoid problem as you described in this video.
Man, this was so helpful. My engine was filled with gasoline. Engine didn't start. Somehow I decided to change the oil and wow , it was more gasoline than oil. You are an Angel.
1 week of chasing symptoms and cleaning and replacing parts - wish I saw this video a week and a day ago! Thank you.
This video saved me. I had gas drain into crankcase and lock up after engine died from lack of fuel. Replaced fuel filter. I had to order solenoid and I put a shut off inline. Thanks for the information.
Soooooo many people think that solenoid stops fuel flow! Thanks zip!
Yep....This is an older video so I made it a point to change the TITLE so all who watched knew it was the float and not the anti backfire solenoid. Ironically, it's one of my top viewed videos, but the bottom line is an ounce of prevention. Thanks for stopping by Buddy! Cheers! Zip~
Zippo every time a see a craftsman vid with engine problems I recommend this vid so our friends on RUclips will know how to prevent disaster.
59chevt I appreciate that 59!! I hope it helps save blown engines!! Cheers my Friend!! Zip~
A friend had her mower blow up. I didn't look to see if it was cracked like this, but it had definitely blown up inside. Now I know why. Thanks for the education.
Good to hear you say that the solenoid is not the problem. Fuel in the crankcase is a float/needle valve problem.
I left the video up to show we all make mistakes and I certainly own mine. It's a popular video with other good information, but the anti back fire bit me with my statements. Thanks for your support Martin! Cheers!! Zip~
Both
Thanks Zippo. I've seen a crankcase overfull several times & always caught it during Pre-start oil level check. I bet that gentleman will double check it from now on. I never thought of it Blowing up though! Wow! Great tip on the fuel shutoff valve, I've been doing that for years now. I fixed a solenoid stuck down because fine sediment settled around the plunger, locking it down. It took a while to blow it out with air gun & brake cleaner & finally oil to work like new!
Great video. We've also seen those fail to retract causing a no-start, but much more commonly to just leak. I like to use the kit for earlier models that comes with new gaskets and traditional bowl bolt and add the in-line shutoff valve, eliminating the solenoid altogether.
Always remember to check your oil before starting an engine!
I made it 14 years with my very similar Briggs & Stratton before it started to drip, the fuel smell tipped me off I was lucky. Feel sorry for that guy he took such good care of it.
Added one of these shut-off valves to my B&S 14.5HP Intek several years ago. It works great and I also use it to kill the engine after each mowing. I never leave gas in the carburetor.
That's what I did / figured too, but such a hassle. Various circumstances, we want to stop and do stuff then start again>PIA. Same thing happened with my motor bike. Rebuilt carb on it, plus put a little two cycle oil in the gas. Think it's the ethanol.
Never ever
I just want to say THANK YOU SIR !! you may have just prevented me from destroying my 90 year old mothers engine. OMG that could have been a disaster.
Thank you Im in the processing of cleaning the carb on my 2003 yardman 18HP briggs and stratton, It keeps flooding into the oil pan, I putting a cut off valve in tomorrow. Thank God it didnt start today with gas in the engine, It poured out. its airing out now for 3 days till my new filter and screen and vacuum hose comes in, I will be putting in that cut off valve Thank You Man God Bless You.
Glad you found it helpful Steve! God Bless You Also! Zip~
This just happened to me the other day, but my engine hydrolocked. I popped out the spark plug, let it drain. I have a fuel shut off on it now and I guess I need to get a new spring or a whole new cellinoid for it and change the oil. Thank you sir.
Excellent, informative instruction....I learned and that is a good thing....I'm a former HVAC Chief Instructor and appreciate other good instructor's....Very well done.
Thank Vernon! I do try to give clear instruction as best I know how. Cheers! Zip~
I have a 2005 in really good cond. This just happened to mine, luckily I caught in time and it didn't blow. Sure glad I came across this video, It saved my tractors ass. LOL thanks a bunch!
Wow... thank you thank you thank you... you saved my Tecumseh engine. When I bought it used, the previous owner had a shut off valve on the gas line. I always kept it on. Now I know why it's there. I'm going to change my oil and start using the shutoff valve when it's parked.
Thank you so much for the perfect info. I really do appreciate it.Thank you well explained .you are awesome.
Thank you Zippo for your reply I have a small engine repair garage here in Ireland love all your videos
That is awesome!
Damn,thanks for the tip!! I recently bought a used craftsman riding mower and noticed the oil stunk. I'll definitely be purchasing a shut off valve and change the oil asap. Great job Zip!! You my friend have gotten a like and a new subscriber!!👍👍
Another good reason to always check oil level before firing up every time... great video my friend and sage advise indeed.
Thank you greatly Lou! I get quite a bit of feedback on this particular video and it's saved a number of engines that otherwise would have ended up in the scrap heap. Cheers! Zip~
I do that and sniff it to to make sure its ok to go
Wow, I’m glad I saw this and read all these comments. Pretty sure you guys saved my engine. Changing oil and adding a fuel shutoff tomorrow, cause I know there’s gas in there!
Oh, and a carb rebuild.
if you have a floooded crankcase check floatin the bowl plunger is stuck open solenoid does not caues this
Thank you for making video, recently discovered the failed solenoid on my engine and cleaned fuel the bowl out and float. I still have good compression engine, I will follow your steps in your video to safe guard my engine . Once again great explanation on the solenoid open & close valve.....and how it works with the fuel ! Have great day !
Replacing that Solenoid is expensive. Disable it and get a Shut Off Valve and do it Manually and it will good for Storage as well. At least you know your Fuel and not flooding the Engine. They made this aka " Solenoid " to make more money out of you. If you look at the OLD Lawn Mowers... They don't' have it and RARELY backfired... Some People claiming that disabling it and it will, BS... I tell you... Save yourself some Money and Disable it... Did you check how much they are? Some as much as $180.00 on Certain Models :(((((
That was a damn fine video!! the first person that gives this a thumbs down needs to watch this again. Your videos are always well explained. Thanks Zippo!
Thank you, this just happened to me on my mower. Luckily it wouldn't start, your video explains so much.
Mine has been doing the same thing since last summer. I would just pull the spark plug, turn the motor over to clear the cylinder of unburned fuel. Throw it back in and mow.
I must be lucky my motor did not lock up or throw a piston rod! Thanks for the tip.
Any time fuel gets into the cylinder, you can bet it'll also drain into the oil. You did get lucky, and I hope with a fuel shut off, that the problem is no longer. Cheers Steven! Zip~
Great detailed video I really appreciated this thank you for explaining the damage this can cause. My 16 hp kohler has fuel in the exhaust every morning
Same mower, pulled the plug out cause i suspected hydro lock engine full of gas! This video confirms! Fuel line shit off installed! Thank's for the video brother!
Great advice it happened on my snapper. It did not have a solenoid but over the winter gas got in the crankcase. We ran it before we figured it out. It did not blow the engine so we changed the oil. After a couple of hrs running it started knocking. $500 later I had new engine delivered, a better OHV one 11.5hp to replace the 9 HP L head.
I've seen several of these. This is good info to get out there. most people just don't know. Good video!
well job done the backfire solenoid just went out of my mother's unit and was not aware that that could be a potential issue good to know and thank you
Yep, just found same issue on a 17hp InTek... drained the oil... way too thin, and smelled more like gasoline than anything. Did not know the details about the fuel solenoid, figured it was a float/valve issue inside the bowl. Will address asap. Great video, thanks for sharing!
Thank you. It was just happen stance to see this video. That is exactly what happened to my mower. I did not blow the engine.
You just save me from misery with your video i have this issue
Great video Special ty
Thanks for the video! I was blessed; the mower didn't start. I've ordered a new carburetor solenoid, but will be installing a shut off valve and changing the oil also when the new part gets here. I bought the mower used but the previous owner had just rebuilt the carburetor before selling it to me, so I don't think it's a float problem. Thanks again!
So glad you found the issue before starting the engine Vic! Zip~
Well, we'll see. It stopped in mid-mow like I had a flooded engine and wouldn't restart. Tried to start it a few days later and still wouldn't start and had a lot of smoke. One friend told me it was because of the oil/gas mix and another friend told me it was because I scorched the piston rings. So we'll see. Ordered a new solenoid that will be getting here this week and drained all the old oil (more like a black oil and gas mixture) and will be putting new oil in it. Am also changing out the air filter (it was filthy; I wonder if that had something to do with it), oil filter, fuel filter, and am installing the in-line shutoff valve like you suggested. There's no crack in the engine that I can see, so I'm hopeful it will work when I get everything back together.
Thank you for your video. I think I just save my mower. I thought it was the carburater. Was getting ready to fire up when I checked the oil and found gas in The oil. Found your video and the solution. Thank you
Well. Now I know why my dad blew up. He just bought a new one, thanks to you I'm gonna get a shut of valve and put it on for him.
Dad's. My dad himself did now blow up
Thanks Jack, that is my lawnmower's problem. Happily I checked the oil stick before it blew up.
Good deal Lou! lol...(Unbox Therapy's Lou calls a camera Jack in case you didn't get the reference) Cheers Cliff! Zip~
Whew! Thanks for the information. That is the type of engine in my Simplicity and I had no idea that this could be a problem. I almost always check the oil before starting the mower but you can bet I'll be following your suggestion. Thanks again!
Yep.!!!!! This just occurred on me this week. Wouldn't start at all. Come to find out the oil had about a half gallon of gas in it.
Great vid. Working on this BS now also adjusting the valves.
I've got a video on adjusting the valves on the OHV Briggs as well. Best of luck to you! Zip~
Wow on that video, Today started my craftman YS4500 22 hp started after 3 cranks was sitting bit i cut my back yard, was cutting my front yard and all sudden white smoke poured out under hood and died cold dead, i said what hell, chased problem as fast as i could right to dam fuel solenoid, it burnt up dam black plug-in and connector was clean , it shorted out "WHY" So now i got replace it and Intall fuel SHUT OFF Valve as you mentioned thanks for explaining this in video and Saved me 600 bucks + on new 22hp engine or burnout tractor that these fuel solenoids are problem
Just saved my ASS by watching this did not know about solenoid shut off.Been out of the loop for a couple of years and just like everything else make something that fails instead of leaving things old school like a simple gas supply shut off.Motor casing filled up with fuel,Drained oil,gas,filter,blew out with air let sit added new oil turned over with plug out,changed oil again installed a manual shut off for gas .Up and running no issues good compression Thanks great Vid Zippo
I get a lot of "Thank You Zippo" comments on this particular video and I'm glad I helped to save another engine! Happy Mowing! Zip~
YOUR INSTRUCTION AND YOUR HONESTY, YOU ARE MUCH APPRECIATED, I HAVE LEARNED FROM YOU. THANK YOU AGAIN. SV
I appreciate very much you sharing your knowledge with us, I am sure it will save us lots of headaches in the future. Thank you.
Wow it’s fixed. I drained oil put in for safety a in fuel flow valve. Then tackled smartly removing wire plug on bottom of solenoid from carburetor bowl. Checked voltage with meter 12.67 volts good. Turned key on and off to see voltage change from 0 zero to 12.67 volts all good. With 7/16” wrench I removed backfire solenoid. There it was ! stuck in retracted position. I had to use pliers to lightly pull the plugger back out. Worked it a bit. Used a little lid cut away bottom of water bottle with small amount of gas to wash the plunger side of the selenium back and forth. Gas color turned brown “rusty look” then it worked freely back and forth. Then I hooked it back to the plug and used tractor key on and off repeatedly watching plunger go in and out. Worked good. Reinstalled the solenoid. Then wasn’t sure if once install again was it working inside where I could not see, confirm. Testing with key I could neither here or feel the solenoid working. How was I to know whether or not I had a possible bad fuel float needle valve problem? How could I test it inside there a top the float. Started up ran great no longer strong fuel smell. I cut grass it Used less gas. Engine ran better. Then it dawned on me to test for sure if fuel needle valve was working properly and it did not need to be replaced as well and it also wasn’t also a cause of leaking fuel, I disconnected the wire harness plug from the bottom of the solenoid while engine still running at low rpm. If working right the solenoid plugger would release spring which would push up the float in carburetor bowl causing the fuel flow pin valve to shut and the engine would stop. Bam! The engine stopped mission accomplished with very minimal work. Thank you guys all of you for your help. You guys are awesome especially our leader. You saved me from accidentally ignoring what would have blown my 20 hp motor cracked block costing me $500 to $800 bucks what a God send you all were. That guy who did the video of the cracked block was awesome too.

I'm glad I kept looking so I could find this video!! I've been having this same problem for awhile. Had people work on. I've done what I can. But this is the FIRST time ANYONE has said that's a fuel shut off. They told me it was for back firing. I must be extra lucky. Been a year now. As far as I know motor is fine. Going to pit fuel cut off on and change the oil. Thank you very much!!!!!
Thanks for the video! That just happened to me. I wasn't sure until I dropped the oil plug and 3 gallons of fuel poured out. Now I need to determine next steps.
Next step is to let the engine air dry for a couple days with the spark plug out, the oil drain open and oil dip stick out. The fuel will evaporate naturally. Pour a little transmission fluid in the spark plug hole and spin the engine over for a few seconds, or purchase a can of PB Blaster LMT (Lawn Mower Tuneup in a can) and spray that in the spark plug hole. Then, install a fuel shut off in line near the carburetor and always remember to shut that off BEFORE you shut the engine down. Fill with oil, add a new filter and you're back in business. Cheers!

My mower stalled while mowing. I did some brief quick electric checks before towing it back to the garage. The switch had Off Run and Start. In the On position, the solenoid is retracted.. I forgot and left it in the On position. Left it there to go look at the electrical print, grab some food and take a little nap. When I returned the garage floor was covered in gas, probably a gallon had spilled, and it was dripping steady out the exhaust. The float needle is deformed so I ordered a new one. Just wanted to tell that story because it made a VERY dangerous condition. The garage was heavy with evaporated fuel and in the garage is a massive old central vacuum of the kind with ancient motors with open cages where you can see a heavy circle of sparks around the commutators as it runs. Scary to imagine if someone had turned on the vacuum.
when you check the oil stick a match to the oil. if it burnes there is gas in the oil. if no burn there is no gas in oil.easy but good check. hope this helps someone.
Doug Lee mom
@Joe Johnson you would have to go through a whole box of matches to get the just the oil to light
Good tip Doug.
I got so much contaminated oil out of a mint Craftsman I scored for $75(nearly two gallons?) I put it in an old chainsaw and it never skipped a beat
I have at the wire harness connector a cut white wire and no after fire solenoid on my first repair 31H777. Had a rough looking screw and washer in the carb bowl and was missing a rocker arm lock screw and half the nut on the aluminum rod rocker arm. Fixed that and gapped to 0.003" and 0.005" respectively.
However, noticed fuel smell in the oil and seemed thinner, so changed oil (probably will again after this) and just swapped carbs with one that has the shut off solenoid. Since was after firing if the fuel wasn't throttled down low when turning off. Plus was misfiring sounded like when throttled below the notched throttle position. Not sure if too lean and RPM's need to be set or governor or needle and seat in carburetor. That's why I figured I'd swap carbs first. Spark plug gap is in spec at 0.030".
Measured 12V is coming out of the cut white wire at the connector. Figure I can tap into that if the plug comes out of the connector, since putting on a afterfire/backfire solenoid. I'm not sure what the current rating is so if needs a resistor to current limit. So I don't don't fry the backfire solenoid... figured I'd ask and see if there is a current limit or what the rate current is on the backfire solenoid. Guessing from the one wiring diagram I found online everything is the same current coming from the starter solenoid. Figured better check though.
Update: yesterday I installed a brand new aftermarket carburetor on my 21HP Briggs platinum engine. It too has the very same fuel shutoff solenoid on the bottom of the bowl. I heard it working properly and expected that the fuel from the tank would not be depleted. I was correct in my expectation, the engine is no longer flooding out, and the new carb and fuel shutoff solenoid is working perfectly to make sure that the engine isn’t full of fresh gasoline. Thank you again so much for the video and explanation and you may have just saved me several hundred dollars in repairs or a new engine.
I would also install a fuel shut off for piece of mind Justin. Another issue that can creep up is the needle and seat in the fuel bowl can fail and fill the cylinder with fuel. Food for thought. Zip~
Justin090587
Just had a fuel pump go bad on my JD LA135. Wanted to find out whether or not a shut off was a good idea or not. Thanks for a great video and explanation!
I'm "lucky person" number 398 (398 and 399 if we're counting lawn tractors). Great info. Thanks!
I hope it helps you out Ray! Cheers! Zip~
My Briggs does this. Gotta remember to use the shutoff, otherwise, I drain a quart of gasoline out of the crankcase every time. Stumbled upon the problem when it ran terrible and I checked the oil only to find it was all gas in there! Bad situation. Use a shutoff! Good video bro!👍👍🇺🇸
Excellent info Bro ! I'm having that problem as we speak. I'll save my engine. HooAh !!
This happened to me ,I thought it was my battery at first , so I decided to pull spark plug an then cranked it over a few times an gas shot out like water , put plug back in , it fired up like normal.Did a oil change an installed the fuel shutoff valve ,runs great!!!
I'm restoring a Husqvarna with a 15 hp kohler that has one of those anti backfire solenoids. It was toast, the wire corroded and fell out. They will do as you said, fail and fill the case with gas. Not good! Great video, what a nice looking AYP mower. Too bad the motor blew.
Craig Arndt The story on the Craftsman went a little deeper than what the video depicted. Turns out, the previous owner sabotaged the engine to justify to his wife that he needed a new mower. It worked, as he now has a brand new zero turn, but to intentionally drain all the oil and run the engine until it blew was just sacrilege. The Craftsman will get a new lease on life with a heart transplant and go to a good home I'm sure. Now to source a decent V twin or higher HP single Briggs and bring it back to life. As always, Great to hear from you my Friend! Cheers!! Zip~
Disable it... They are telling you BS.... I have disable these on 5 of our Mowers so far... None backfired... Best is to get a Manual Shut Off Valve. During Winter Storage... Shut off your Valve... Let the Engine Run until the Carb empty and die... Push the Mower in your Garage or Shed... But let Engine Run on it's own outside so no fumes. You will be good for Winter Storage :)))
The needle and float was the exact problem with flooded crankcase. Solenoid was not an issue on 9 year old craftsman 21 hp Briggs. Carb rebuild kit fixed along with new oil and filter. Was fortunate nothing got damaged.
You're exactly right Aaron. I corrected this in the title and description, but I REALLY need to shoot another video on the dreaded flooded crank case. Cheers! Zip~
Just what I was looking for, almost. I just had the same problem. I went to start a mower I had been working with it. I noticed that the gas tank was way low and I thought I had left some in it. It would not start, in fact it wouldn't turn over. I had been working on that very problem and was disturbed to think it was back. I had adjusted the valves to try and fix a 'too much compression' issue. I decided to pull out the spark plug and put it back to prove it was compression causing it. Well, that is when gas poured out of the plug hole, pure clean gas. I cranked it until only a gas mist was coming out of the plug hole. I thought it was weird my oil level had gone up recently, and it seemed a bit thinner too. Now I know why. It just so happens I had added a fuel shutoff valve to address a bad solenoid (rusted opened), to fix a backfire issue. However, I had forgotten to close the gas shutoff valve the last time I ran it... So I put the plug back and tried starting it and it did run, perhaps louder than normal. I think I need to flush and replace the oil... I assumed this problem was caused by a faulty solenoid and me leaving the gas line open. Reading your comments, you are suggesting a needle valve may be the actual cause??? I didn't want to mess with the carburetor yet, so for now, i'll change the oil and be sure to close the shutoff valve and see how that behaves. Maybe the needle valve wont matter, we'll see. Thanks for sharing the info.
Definitely going to do that I have the identical engine and fuel shutoff solenoid. My problem at present is that the solenoid isn't opening preventing fuel flow through the carburetor. I looked at another video that recommends cutting the plunger off with a bolt cutter so that fuel will be able to flow. He said that he didn't see any problems after he's done this to multiple engines. He apparently repairs mowers for a business. He does say to install an inline fuel shutoff, but it's late in the video and somebody that says "Great problem solved" and doesn't watch the video through to the end is going to miss this important step.
I did that on my kohler courage, works fine but you need the shut off unless you want to leak fuel.
as updated by video maker the ABS only shuts off fuel to the main jet , it won't stopped bowl from flooding if needle/seat fails in its job.
Thanks Ken! I always keep my flubbs and mistakes left on the videos and make sure I let everyone know where I went wrong. I appreciate your input!! Cheers!! Zip~
I had the same issue with mine purchased new Solenoid and fuel shutt off valve not to mention it's nice to store mower on a empty carburetor
The deal is to always without fail, check your oil every time before starting the engine
You're spot on with that advice Ray! Zip~
Thank you. I believe you saved my engine. Thanks for the explanation.
No problem 👍
When you are done mowing, close the shutoff valve and allow the engine to idle until it dies from lack of fuel. Leaving ethanol fuel in your float bowl when storing your engine is a really bad idea!
Exactly right Roy!! I can't tell you hoe many carburetors fall victim to the effects of Ethanol. Cheers! And thanks for posting this! Zip~
A local shell sells ethanol free fuel for tractors and such here, so Im switching to that. It costs a little more, but its worth it in the long run.
You're a good man, may God bless you.
Thanks bud. Very useful informations. Keep up the good job.
i have same soleoid 21 yrs still working fine ---old chrsftsman mower
Thanks for the great info!! I have avoided detonation.
Thank you. You just probably saved my engine and solved my problem.
Excellent video. I'm having drama's with a 23 hp horizontal, missing & backfiring, but I'm getting there. Briggs & Stratton are stumped as to why it happening as well. Grrrr.
Check my videos on the Conquest tractor Slim. I cover a lot of common issues in that video series as well as some not so common. Lifter drift, bent push rods are a possibility due to engine over heating which causes the valve guides to move. I also have a number of videos on that subject. Good luck with it and keep me posted on your progress. Zip~
Problem solved. Finally. The shop gave me a 2nd hand engine to remove the carbie from, & fit it to mine. Ran like a dream, so I ordered a new barbie, put that on today, & away it purred.
My Briggs & Stratton V-Tech 25 horsepower is 15 years old and finally had to replace the carburetor as I didn't find rebuilding it worthwhile.
Thanks , I had this problem yesterday , going back today to change oil and inspect block, although it did run for 45 minutes after stalling the first time and then I just disconnected the fuel line and it ran out of fuel, but the manual fuel shutoff is a cheaper fix.
Yep... had gas in my troy bilt 19HP. Dealing with it now. Thanks bro!!
Thanks for sharing, Zippo!! I've got 2 of these engines. Great tip.
Thank you! This is just the information I was looking for!
I hope it helps out! Cheers!! Zip~
Noticed the Allis Chalmers in the backround 1957 ? Awesome ! That tractor is the one worth talking about.
Thanks Gordon! That's a 1964 Allis Chalmers B-10 as is the one sitting in front of the Craftsman. Their names are "The Old B-10" and affectionately, Ugly-Alice. I've had both of them in numerous other videos in the past. Cheers! Zip~
When I was about 8 years old (1971) my stepbrother found a B-10/1957 at the local tractor store They could not seem to get it running and sold it for $25.00 with delivery. My stepbrother had a 1947 Aeronca Champ plane he was also working on. He had the tractor up and running shortly after the delivery guy dropped it off. We mowed the three acres that evening. I owned that tractor until I was 35 replacing minor things along the way. Finally sold it working 100%. I miss dear old Allis.
The first year of the B-10 wasn't until 1964 unfortunately. In 1957, Simplicity (makers of the Allis Chalmers line of Garden Tractors) was just launching their 4 wheel tractor line up and the first model was a 1958 Simplicity Wonderboy 700. The B series Garden Tractor for Allis Chalmers wasn't introduced until 1962 with the B-1. Prior to that, the smallest available tractor by Allis Chalmers was a Model G, It was a rear engine model designed for work around the homestead to plow small gardens, mow and grade driveways and other less Herculean tasks usually left to the bigger Brother Allis line of machines. You can go to Simpletractors.net to view the timeline of Allis Chalmers which runs in conjunction with the Simplicity line up. Cheers Gordon! And yes, they're amazing machines! I mow 3 acres with a 54 year old Allis B-10 and it never lets me down.
Good job so true ~ Any mower i send out the door has them on it .
How often should I change the Carb Fuel shut-off Solenoid? I get the impression it should be changed on a regular basis so that the fuel doesn't enter the engine in mass quantities causing a cracked block, etc? How does one avoid that happening from the guy's tractor engine? Please be more specific as to why the gas incident to the engine occured...
So a shutoff valve should be installed on any mower where fuel is supplied by gravity. Correct?
It's an ounce of prevention DXT. Even with mowers with the tank below the carburetor, fuel can still siphon into the crank case. It's just good practice to install fuel shut off valves in general. With the Ethanol (that pulls moisture from the air) in our fuels, the down time these mowers see in the off season can easily cause cavitation to occur which will in turn cause carburetors to oxidize and fuel line linings to deteriorate. So, install the shut off, turn the fuel off and let the engine run until it stalls. This will protect the carburetor and fuel line forward of the shut off. Try, if you can, to run the mower out of fuel at the end of the season or treat the fuel with Sta-Bil 360 SMALL ENGINE formula. Zip~
Thanks!
ZippoVarga i installed a new carburetor and a fuel shut off but still getting gas in my oil . What’s next ?
@@michaelsimsplaya4199 what i do when I'm finished with the tractor I shut the valve off let it run dry,no more gas in my oil.Restarting open the valve no problem.
It's almost worth it to just convert to propane. Just a hundred bucks or so could get you a conversion kit and save you a whole bunch of hassle. It burns cleaner and the valves right on the tank.
I'm that "lucky person" tonight.....THANK YOU
I hope it takes care of things Man! Cheers! Zip~

The solenoid is called an anti backfire solenoid. It prevents fuel from going into the main jet after the motor is shut off but still turning, to prevent backfire. The intention of the solenoid is not completely shut the fuel off. The needle and seat going bad is the culprit in this situation. The needle valve and seat is suppose to shut the fuel off once the bowl fills.
You are 100% correct and this has been discussed in length in the comments section. I'm always subject to being wrong, and I don't shy away from my mistakes. Instead, I embrace them, and learn from my mistakes. Thank you very much for your input. I've left this video up as a reminder that I am not infallible. Check the description of the video, where I've expressed my apologies for misleading the viewers. A new video will be posted soon correcting my mistake. Cheers! Zip~
Excellent and very informative video . Thank you ! Your videos are excellent!
Good video.... have the matching block - the cracks
Possibly saved my engine ! Thank you !
Glad to know this helped Carbide! Zip~
I wonder how often this happens, if the float valve is sealing there would only be a bowl full of gas to leak into the engine. it's not too uncommon for a float valve to leak,. the older engines didn't have the fuel shut off solenoid, I believe the purpose of that solenoid is for instant fuel shut off when the engine is shut off so the engine won't try to keep running after the ignition is placed in the off position.
MissouriOldTimer This is very true and correct OldTimer. The immediate shut off is designed to deter backfiring. It also can allow fuel to continue to flow once the spring weakens and in conjunction with the notorious bad needle and float in these carburetors, fuel can fill the crank case. The shut off is simply a quick fix to a more complex problem and is the cheapest route. I don't often encourage a bandaid fix, but many want the easy way out, which was the reason for the video. I will post a "how to fix" video in the near future and have done other Briggs carb videos in the past. Thanks a ton for your input. It's spot on with the root of the problem. Cheers!! Zip~
I think every time you start mower check oil . You can usually tell if there is fuel on the dip stick i may be wrong.
Very true Saleem! Also, the level will be quite a bit higher if there's a problem. Cheers! Zip~
This is my second Craftsman with the B&S engine. First one never had this problem. The second one after a few years developed the problem. This was about the time all regular gas had ethanl added to it. I think what happened was the the ethanol ruined the seal on the float valve. I added the fuel shutoff valve and that cured the problem. As long as the engine is running it keeps up with the leakage at the float valve.
Kohler has the same trouble, my oil filled 3 times with gas ,was fortunate to see it before.I installed a shut off valve .When I stop the tractor I shut the valve off let it run dry,to stop the surplus fuel from the carb draining into the oil pan thus damaging the engine slowly.
I believe mine is stuck in the closed position because I have a gas starvation issue, and it will run like a champ with a spritz of starting fluid and the fuel pump is working fine.
I bought the mower for my mother and my sister used it, and she complained that it wouldn't start.
I disassembled the carburetor and cleaned all the varnish and everything looked great, but it still won't start and that solenoid was nasty.
THANK YOU ! WE LIVE ON A FARM AND REALLY DEPEND ON OUR MOWER ! IN FACT THE TRUTH BE KNOWN ! I REALLY OVER WORK THE POOR THING ! OH MAN WE JUST CAN'T AFORD SOME THING LIKE THAT !

Those electric shutoff valves are expensive!
I’d check to see if that were the problem by removing the carb and lowering it to see if gas starts flowing out of it. It’s all gravity fed and will flow through the fuel pump.
Just an idea. There should be a replacement program for this disaster waiting to happen.
It’s a sealed unit with no method of accessing the spring.
They are not. They are around 15 bucks.
