In this video I show my findings as I was diagnosing a no start condition on this troy bilt lawnmower. It is powered by a briggs and stratton 500 series engine. They are very common engines found on most newer model troy bilt, craftsman, MTD, and toro lawnmowers.
This video just fixed my mower sir. I have that engine on a Snapper. VERY difficult to start last summer Removed the valve cover today and the intake rocker is very loose. Headed out to adjust them now. Thank you. Great video.
That’s so great to hear. I hope you got it dialed in and running good again!!
Glad I came across this while researching hoping to see that I was right in determining which valve was which.
I think I was told I was wrong. Just trying to confirm I got it right.
Mower runs good. I set one at 5 thousandths, the other at 6.
I have to back to try to get the intake where it will stay adjusted.
Should I set both of these at 5 thousandths like you did that one?

I have the same issues. All I have left to check is the clearance. Sure hope this solves the problem. Thanks!
Alex, this is exactly what brings me back! I look forward to your videos. You have such a calm way about you and explain things so well.
Thank you. I’m hoping to make things easy and clear for people to understand. I really appreciate your support and continuing to come by the channel. 🙏
What is that silver flat tool that you are using?
You're awesome in your repairs..cool,calm, and collect and very adamant but not obnoxiously induced
I really appreciate that!!
Great job on the valves and good information, thanks
Thank you for stopping by. Hopefully this helps fix some people with preventing issues, or fixing issues they have with their valve lash.
Great tips as always . I got one I think I need to do check the valves on here soon as it has some chatter on startup . Congratulations on 300 subs 🔧👍🤘
I overlook these a lot. Hopefully it’s an easy fix on the one you have with a little chatter. Thanks you as always for stopping by John. I really appreciate it 🙏
Cool I haven't set the valves on a push mower yet! Good find and good lesson!
I’ve shown a few of the carb cleans on these machines, but yet to show a valve adjustment. Hopefully this helps someone, and glad I got to the bottom of the no start condition. Thanks for stopping by as always 🙏😎
@@freedommowers420 Definitely helped me!!!
Tha is for this video. I HV one that i mest with and didn't understand how to set it back. Now I HV a idea of how to do it. Just got into the small engine thing. Luving it. Fix's about five in my first two day.
And once again you popped up without your beard and scared the crap out of me!! 😯🤣
Good job on the catch and nice job on the video bud, she's purring like a kitten now. 👍
Thanks John. It’s easy to get scared by this face. I do the same every time I look in the mirror 😂. I was glad I figured this one out. Other than valves it most likely would have just been a worn out engine.
LoL.... you did good, saved another one brother. 👍
Nice how to video Alex. Alot of mowers get tossed because of that valve issue. That mower is ready for sale. Your probably cutting grass already. Our grass is starting to green up but we had about 1/2 inch of snow 2 days ago. 👍🇺🇸🎥Roger
I’m guilty of overlooking the valves on these motors a lot. I’m glad I caught it though and it’s ready to be sold. I’ve got a toro revival video coming soon thanks to someone awesome. Yes I’ve already been cutting this season, but I hope it stays warm your way soon. Thank you as always.
I’ve got one just sitting in my garage. I’m going to use it as my first project now thanks
These machines are pretty easy to do a lot of repairs. Thank you for stopping by. Feel free to ask questions if you need.
@@freedommowers420 You definitely boosted my confidence, my problem I’m scared to make the problem worst, thanks!
Very nice work brother! I hope all is well down your way! Keep up the awesome work!
Thank you brother. Yes all is well this way. Very busy, but that’s a good thing. I hope the same your way. Thank you for stopping by 🙏
Very clear instruction and understandable. My timemaster Toro has problems starting and bogs down easily. Not sure if it is this issue or head gasket or both.
Great instructional video. Thanks.
very nice work
Thank you for stopping by! I’m hoping this helps some folks out, and keep those mowers running longer.
Great video. Good job brother. Thank You very much.
Glad you liked it!
How's she goin'? Nice repair Alex. That was a good find to check those valves. Man that intake was some loose eh!! All fixed up now and ready to go mow!!! Take care!!!
Hey hey!! Hope all is well your way. Thank you for stopping by. Yes I’m glad I found the valves to be way out of spec and give me a chance to make a video. It’s running great now and ready to mow some grass.
I have the Troy built 240 and it just quit running after I cleaned the carburetor and flushed the gas tank then I opened the valve cover and walla, lose rocker arms and a quick adjustment and now it's running smooth. Thanks for the help.
Nice job!! Best of success with your site! 😃
ALEX YOU ARE THE BEST! I've been ready to throw this mower into the ocean out of pure frustration! I went through the whole thing! lol the plastic carb bs and I've been so frustrated! You have saved the day bud! Thanks again Alex! 👨🔧🙏

I’ve got a 7hp Briggs on a Toro, I’ve cleaned, fixed, and adjusted everything but this so far. It’s a hard start condition. A couple pulls on the rope, or cranking forever with the electric start, it doesn’t start like it should. I’m going to tart his next, thanks,
Thought I had already posted this. Glad I came across this. I been trying to confirm which valve is which.
I adjust them on one for a friend and chose the top as exhaust like the one you show at 3.34.
I was thinking someone told me it was not but mower ran good for the minute or so I ran it. Now I need to make sure the intake ( bottom) one stays where I put it.

I did not adjust them the same as you.
I adjusted these at 4 and 6 thousandths.
Should I adjust them the same as you did that one, both at 5 thousandths??
Same problem you showed. I've adjusted the valve's before. But when I check by rotating the engine (mtd yard machine e300 125cc b n s) the rocker arm come loose again, won't stay adjusted. Found a small pice of metal (spring pice). Rods are not bent and feel no resistance rotating the engine. Going to check how the valve's feel next and check guides also. Wonder if there might be some internal issue also? Had this mower over 10yr. And I change the oil.
Excellent for my Husqy/ B & Strat.
Great video thank you. I just have one question about the push rod, does it just sit in there all loose?
Great, thank you.
Good video thanks you for video
Thanks for stopping by and showing support joe 🤘
If it’s 2 years old adjust the valve lash 😊😊 it’s going to need it
Awesome video
Thanks for stopping by! 🙏😎🤘
Good content in this video, I never would have thought it could be a valve adjustment issue. That's a cool specialty license plate you have there, is your shop in Ohio?
You set the exhaust to the same clearance as the intake? Shouldn't there be a .002-.004 difference? My motorcycle
set at Intake .004-.006 exhaust .006-.008.
Du you have a video on setzing the fuel needle right - on an older (i.e. 1990s) Briggs & Stratton push mower motor (those that have only one ! governor spring)?
A good video thanks. Do yourself a favour and get a table to place you’re mower on, easier to work and less stress on your knees ect. I have a adjustable one and saves my back picking mowers up. Once again, thanks
Like your videos
I know I am old fashioned but I like the flat heads better they rarely had problems unless they got burned or a seat came loose, but these over head valves seem to need adjusting a lot,, I am gonna have to to that to my Hustler mower with a Kohler engine, the engine starts but it tries to kick back some before it starts, I am guessing the valves are out of adjustment.
I agree. I had much less issues on most flatheads, besides the valve seats coming loose like you said. Seems to be a common trend to over complicate everything. It certainly wouldn’t hurt to check them on your kohler. Hopefully that does the trick.
I just watched your video and I liked it a lot.. you explained everything very well for what I needed to do, so I'm subscribing to your channel hope to see more of your video's.. 👍
Thank you so much for stopping by, and for the kind words. It means a lot!
great video nicely explained
Glad it was helpful!
I believe that if the blade is unbalanced the vibration will make the valve adjustment to be out of wack I did a.video on weed.eater line spool head maintenance. To.make sure you are able take it apart for keeping it clean
I agree. This one had a bent blade on it when I first looked it over. Most likely the bent blade vibrated the valves so bad it eventually loosened up.
@@freedommowers420 I agree with you on this matter a bent.blade on a direct connect to the engine is always a problem in the waiting
Alex, have you ever had a cam lobe move on one of these engines? My daughter hit a stump and now it won’t do anything. Flywheel key is fine. When I picked up the mower it doesn’t pull through like the compression release is working. Been waiting on a new cam from Jacks for about a month now.
Yes the cam lobe can move and several have 😢😢😢
Plastic cam
Great video. The valve over on my 11yr old 550EX is stuck. I tapped on it and even tried to grab in with large channel lock pliers, and it would not budge. How can I remove it ?
Had a 163 cc on a toro ran crappy until adjustment
I'm having possibly the same problem intake valve is a little loose went through the carburetor cleaned in numerous times it'll fire up if you hit it with starting fluid and that's it fresh gas and everything could this be the one problem problem
you just help me thank you
Do you have a video on the flywheel adjustment you mentioned in this video?
Nice work! Seems like these late model Briggs engines are somewhat prone to this. Lack of attention to torque specs at the factory?
Thank you. Yes it could very well be a lack of torque or maybe lock tight. This one did have a bent blade on it when I got it and I think they let it vibrate for a long time. I greatly appreciate you stopping by.
In our shop every engine gets the values lash adjustment to start with if it’s over head values, they AllWAYS are out of spec,once it done it’s starting fluid , tool clamps on plug wire and try to start
THis worked for me!! thank you!!
I’m really excited to hear that this helped. Thank you very much for stopping by.
Why why why...... The tightening bolts on the input and output do NOT have a center set screw. I don't understand. I have a Toro, Briggs & Stratton GTS 140cc, model 21352. ¿????????????
I have a 6.25 briggs troy bilt, leaf vac, I have been troubleshooting and stumbled on you video, maybe u can help me, I've went through the carb and fuel system, it all seems good, it turns over and runs but will not get to full throttle....seeing your valve adj video, im thinking that may be my issue, is tht possible, my apologies if this content isn't for Q & A...thank u in advance.
Like Stella says. First pull!!
Hi how do you know to use the .005 gauge to adjust that lawn mower Thank
Mine has horrible kickback and the flywheel key is good. How does someone check the compression relief?
On these ones I’m not sure. I haven’t had one apart yet.
I opemed the ohv cover 😢 and ever since my lawn mower leaks from there a lot of oil. Did i not seal it back properly?? Pls help.i did screw it back ans now it wont last when its on
Most likely the gasket or seal has an issue. You can use a high temp RTV or new gasket.
What model is that boombox with dual cassette deck in the back, lol?
Nice video, thank you! One bit of feedback, "go ahead and..." could make zero appearances in your commentary, and it would make a much better impression.
Thanks
How do you find a engine serial number? I keep trying to use Pro Chaser to buy carbs for my power equipment which is all Troy Bilt. But I always get sorry we can't help you. ..I use the model numbers like 11a-542q711.
There should be stickers on the side of the plastic cover on the engine or on the side of the engine block. Sometimes they want model and serial number to get an exact match.
I have the same problem
On my B&S engine model#09P702-0190-F1 140cc the valves don’t look like valves you just adjusted , I can’t see a set screw or locking screw to release the adjustment nut . The rocker bolt doesn’t have a center cut out for any type tool, be it a torx, or Allen wrench. I’m hoping that I could find some information on how to adjust the valves on you tube. Thank you and I enjoyed your posts . Please help me if you can,
It’s a self locking nut, just turn it to adjust lash/ clearance
@@philliphall5198 May I ask you, how did you learn about that self locking nut ? Thank you, for your reply to my comment. I’m interested in learning more about that, my research on that was unsuccessful, so if you can let me know where I could learn more then thank you.
Sounds like you might have what I think is L shaped motor with no adjustment nut on the valves.
@philliphall5198 That was my question. I figured it was some kind of fancy built self adjusting thingies. I'm a 78 year old female. I adjusted it maybe 50 times and still cannot fix it. I even have forwarded it 1/4 inch and set it. It still does not work.
@@heyheyyo2389 Great to hear from you, ! I bought the locking nut studs to install in my mower, tried to adjust the self locking adjuster but still have a backfire when I shut the engine off. Am now waiting for offseason to make the replacement with the new parts , adjuster stud and locking mechanism, hoping that will resolve the misfire issue. If you have any other ideas that could be helpful please let me know. Thanks
I'm assuming this would cause knocking if it would actually run but still out of spec? I have the same engine and mine makes a loud noise when starting and stopping the engine. Wondering if this could be the issue.
Very well could be the valves tapping. It could also have something to do with the pull rope recoil on these. I have had some before that would chatter.
Hey Alex, it was a good video. I got mine at 4000 it’s getting fuel and it’s got spark but it still won’t start. About the fifth bullet pops any idea what’s going on with this mower.
It sounds like it could have an issue with the flywheel key. It’s common on these and the timing of the spark won’t be when it is supposed to. I would take a look at that next.
@@freedommowers420 yeah I checked the kids just got a little weird to it. I flipped it around it’s not that far off. I went over your carburetor cleaning, and I did not take that centerpiece out and clean it so I’ll do that again, but I thought it was getting gas.
Cleaning the way you do it still doesn’t start
How much should be 5 to 7000 in millimeters?
Hi why do I get a pop sound after turning off my lawnmower Briggs and Stratton engine 5.5 only after it's turned off.
Maybe it is running rich and has a backfire on shut down.
@@user-bg3kk2pi7b I’ve got the same problem with mine, cleaning the carb didn’t make a difference, so I went and checked the valves. The valves were out of specifications both the intake and the exhaust ,readjusting to specifications helped mine.
@@freedommowers420Fuel solonoid?
Pinched flywheel key possible?
Needle not sealing properly?
Why can’t you just leave the feeler gauge in
I’m sorry I didn’t explain what I meant I was just thinking if you put the feeler gage in the gap why not leave it in there and tighten the bolts and then pull it out and you should have a perfect gap??
You can. Honestly I’m not sure why I didn’t just leave them in. Thank you for the suggestion!
