Life saver!!! I had no compression after messing with this 8 horsepower Briggs & Stratton 4 days, and your video show me how easy it was to at least look in and see the valves. Once I did that I seen the valve stuck open lubed it tapped it down and it started right up! I love you! Thank you so much for this video, it saved more days of wanting to throw tools!
Thanks, I'm glad you liked it.
Carb cleaner is great to clean off old varnished gas. Thanks for watching.
Just purchased an old Montgomery Ward Edger with a 3HP Briggs, did tje compression test and "0" stuck valve. Your video is a big help for me and my 11 yr old son to get this thing going. Thanks
Hey Moe,
I have run across several stuck valves that were caused by the owners running old "varnishy" gasoline in the motor. The Engine, and valves work fine while it is hot, however once it cools the old gooy gas forms a perfect glue and effectively glues the valve into the guide. The first thing I fire down into the valve is carburetor cleaner. If the seizure is caused by gooey gas, it frees up instantly. I use a few squirts of Marvel Mystery where you use ATF. (I simply like the smell!)
Another great vid. Straight to the point NOT telling us the history of the machine you are working on, what you have in your garage, when you built the shop, who you are married too, where you bought your shirt AND then getting to what we tuned in to see. THANK YOU.
+Mark Weaver Haha, hey Thanks.
Lol you must not like movies that much
No shit, when you're watching this, you've just been beating your knuckles like crazy in 10 degree weather. Nice job getting to the point.
Mark Weaver
I gotta agree with you on the " Get to the Point " comment.
I have a low tolerance for long, drawn out videos too.
5 minutes is Great.
7 Minutes is a little Borderline.
10 Minutes or more and I'm using my right arrow to skip to what I need..
Unless I'm doing a complete job or something similar..
You forgot to mention the useless 2 hour introduction..agree, agree, agree, agree agree agree agree (i think you get the point)
This is just what I needed to revive a mower that had not been used. Thanks for sharing your expertise.
+Dillon Menefee GREAT! I'm glad the video helped.
Thanks for coming over and watching. Thanks for the video compliment. -Moe
Thanks for giving your time for the video you helped me get my tiller fixed with no repair shop costs thank you again God bless
You're very welcome. I'm glad the video helped.
Thank you! Stuck intake valve on B&S chipper. Got it going!
Awesome.
Smashing tutorial as allways :-)
love the graphics, it gets the understanding direct to the brain :-)
No over complicated data to absorb, just the bit you need to get it going :-)
Thank you! We just got 10 inches of snow in northern MN and my snowblower woudnt start, it was a stuck intake valve and this fixed it .
Awesome. Glad the video helped. When you put it away, make sure it is on the compression stroke(pull until you feel resistance on the rope). This will make sure the valves are closed, so if they stick then the engine opens them.
Nice video.
Learning from you is easy.
Thanks for showing what can be possible.
My engines with this kind of access have always been down on a mower and facing front.
I shoot them and pull them over to decarbonize valves sometimes, but this gives me more to think about.
Thanks again.
This helped me save a mower from the scrap heap today. After watching your video, I put an engine back together that I was going to part out. After taking off the head, I could see the intake valve was slightly stuck in the open position. I then sprayed a bunch of penetrating oil around the valve and kept tapping it back down flush with the engine block with a plastic mallet when it was supposed to close. I also made sure the valves could be turned by hand.
After putting it back together, it had compression and started right up.
Thanks, I'm glad you liked it.
I have an old Sears 12.5HP tractor that has a sticking valve that pops out the exhaust all the time. I think this will help lots, THANKS!
Hey I really appreciate this video. I didn't know that the valves should be free spinning in the up position. This really saved my mower. Thanks again.
I was working on an old Craftsman tiller with a 5 hp Briggs and Stratton engine. It had been sitting around for a number of years. I was able to get it started the first couple of times without much trouble and then nothing. After I took out the spark plug, I could see that the valve was indeed stuck open. I really had to wiggle the thing back and forth to get it unstuck. I used the penetrating oil and the trans fluid and it began working up and down. It eventually started. Now is running good.
MY FAULT but you saved me a ton of work. I tried using some 'older' gas (just to use it up) in a new rebuild. Big mistake. The 8-HP B&S started and ran but after it cooled down, the intake valve stuck open with NO compression. FIRE shot out of the carb.
I used PB Blaster but now I think carb cleaner would work even better to dissolve the varnish deposits on the valve stem. Freeing the valve using a screwdriver was not easy. After tapping hard several times, the valve finally snapped shut, compression returned and now the generator works just fine. Thank You.
Hello, this video sounds extremely useful to me, as I have a similar Tecumseh 10HP, with the valves stuck, I believe. It was running great, then standing in the open for quite a few years. Now I tried to bring some life to it, it has no compression at all, and I could see through the spark plug hole that the valves did not move when I cranked the engine. I thought to open the engine, but after watching this video, I might be able to save some job there. Thanks!
Easy and simple way to diagnose/fix valve issues without having
to pull the valve cover and head............Great video thanks.
Hey Thanks.
That's great to hear!
Nice i was going to take it apart but this worked for my snowblower.I noticed it lost power and the muffler was glowing red at night.Now i an tossing snow 20 or more feet and no more stalls or spits and sputters.Thanks a bunch and have a great day.
Awesome.
Awesome info man.. Thanks.. would have cost me a ton of money to fix. Appreciate your time in making this video.
Thanks for your video! In 5 minutes we had our tiller up and going without needing to buy a new engine!
Nancy Holland Awesome.. I'm glad it helped.
That's great to hear.
Thank you. That was really helpful! My generator wouldn't start this morning, no compression. I suspected the valves. After watching your video I took the plug out and shot some WD40 on the exhaust valve. I couldn't turn it around because it was too tight to get a screwdriver in there. Put the plug back, and it started first time. Have compression again! Cheers.
That's GREAT. I'm glad they video was helpful.
Great video. Mine wouldn,t start after lunch although had been standing a couple of years. I'd already taken off the head so lubed and turned the valve by hand.
Easy fix and back running in 10 minutes.
Thanks.
+Neil Tong Thanks for watching.
I really like this vid!! simple, polite and respectful, to the point, familiar with the details, short and sweet message. Good style bro!!
Thanks, I'm glad you liked it.
@@sixtyfiveford
yep.
BTW, im 65 and my first ride was a 65 custom. 4 door cruiser, white over black, 390 interceptor with the pull cable overdrive. No door handles in the back seat, made dates antsy,ha! first gear to 30, let off the pedal, and then to warp drive!! Well, at least back then...
and war pigs or black dog on the speakers!!!
You saved me from tearing a troybilt horse techumseh head off. Took a couple soaking over two weeks but it freed up. Zero dollars for a working tiller. Thanks
Awesome
Great tip. I have two small engines to try this on. one is a generator and the other is a modified lawn tractor with a bucket lift. Thanks!
Thanks, I'm glad you liked it.
Thanks A lot! I got a free engine that had no compression and this revived it!
That's awesome.
Very good trick and explanation ( originally I could see the edge of intake valve but wasn't positive it was really it and or if it was stuck ,it is and was ) but I was so involved trying to turn it with the screw driver I almost total stripped out the Spark Plug Threads !,!
Thanks for this! Got my Briggs running again.
Thanks, I'm glad you liked it.
Had this problem (no compression and could not start), squirted in some PB Blaster, let that stand for an hour or so and then squirted in some transmission fluid and worked the valve loose. Hammered a chopstick on top of the valve to pop in back in fully and this really had it going when I spun the blade. Started and blew out some smoke but seems fine after this. Thanks for the advice and the video.
That's great. I'm glad the video was helpful.
thank you, one of the best how to videos I have ever seen.
Danny Manha Thanks, I'm glad it helped.
Excellent video, thanks for sharing that with us 👍
I appreciated the diagrams and the suggestion to look under the spark plug hole. The intake valve was stuck open and I was able to free it up.
Glad it helped
I would check for spark when it dies. Your symptoms are that of a failing ignition coil.
Another option is a plugged vent on the gas cap. Check this by loosely attaching or removing the gas cap and trying to get it to run.
Good deal! I started using the Sea Foam Deep Creep and seems nice. Funny, is I use the WD40 more to coat thoroughly what's sitting outdoors. Thanks for sharing!
Thanks for watching Bill
-Moe
Excellent work sir! Thanks for your time. Helped me a lot.
Nice fix. Thanks for another great tip!
Very Good 65! I have a similar video showing how you can remove the muffler and pinpoint lube the valve guide as another option to free a stuck exhaust valve. I can't count how many vintage engines I've acquired with this very issue and I've used your method as well. Again, Great execution on the explanation of how to free a sticky valve! Cheers!! Zip~
Thanks. They always seam to stop with a valve open.
I heve a similar one on the pullcord black case hase no code or nothing
Great video, well explained. I will be using that method to free up a stuck open exhaust valve on a 6,000 watt Generac generator that has a 10 hp Tecumseh engine.
Great tip I have that very problem on my snow blower. Thanks
Robert SLOAN JR. Thanks, hopefully it helps.
Thanks for the video. Same problem with a Briggs on a small tiller. I'll give it a shot this weekend!
You're welcome. It's always something small with these things.
That's actually a difficult question. Most of these small engines have a cam mounted compression release that deactivates at a couple hundred rpm. This throws the off your compression reading. With that said most engines I have tested are around 70+ psi. If it is lower and adding a little oil to the cylinder dramatically increases the compression reading then the rings are shot.
Great tips, sixtyfiveford! Thanks for sharing the info. You got a "thumbs up" from me. It is my experience that a good mechanic will share information because it is his/her desire to help others. Yes, I called you a good mechanic. Lol
Thanks. I hope it comes in handy.
Thanks Joe.
Thanks a bunch. You saved me a lot of work and or buying a new generator.
great vid! gonna give this a try on a 8 hp briggs powered manco 3 wheeler I just got.
Thanks for your video and explanation. I'm going to try this on a tractor.
Wayne White Sometimes just a little tap and they fall like their supposed to and sometimes they take a little work. Let me know how it goes.
Very nice! Easy to follow video.
I’ve had great luck with marvel mystery oil: engine treatment. Half the bottle in the gas and the other half in the oil. Worked on a Mitsubishi Mivec engine that went +30k miles on an engine change and a Toyota pickup that sat for years
I had the same problem today . great video
Thanks, I'm glad it helped. Remember when you put it away, to pull the motor over until you feel resistance. This will make sure it is on the compression stroke, so both valves are closed.
Saved me a ton of time! Thank you!
Thanks for the response Moe. You were right, the engine loses spark when it gets hot so i guess I'll be trawling ebay for a new coil. That is unless you've got a "how to fix an ignition coil without trawling ebay for a new one" video that I've not seen yet. ;-)
Thanks again for the advice and all the very best of luck with your channel.
Excellent! I hope this works. I need my tiller!
You are the man! We have another big storm on the way. My old Craftsman is ready to go. I thought it was junk. Thanks.
Scott Skinner Great.. Glad the video helped.
Thank you sir.
You are a very clever man. Thanks for your video.
S. Dogantimur Thanks Buddy.
Thanks for the vid. Really easy to follow.
Thanks.. Glad you enjoyed it.
Great advice, thank you.
Thanks, I'm glad you liked it.
Thanks for the tip! Great Idea!
I'm glad it was helpful.
Great info, Thanks.
Bill
For sure...
Great video Moe.
Great video . Thanks
I HAVE A 5 HORSE BRIGGS WITH A STUCK VALVE, AND AM GOING TO TRY YOUR METHOD AND HOPE I DON'T HAVE TO REMOVE THE HEAD. THANK YOU FOR SHARING...
Duane Hampton
Let me know how it goes.
thanks
Now you just need some snow and you're good to go. Thanks for the vid.
Thanks, I'm glad it was helpful.
Very common on these Tecumseh snow blower engines is the valves loose their clearance due to wear, in which case you can re-grind them and lap them. A bit of a daunting task if you have never done it, but still perfectly doable.
Yes, I've done many a valve jobs on Tecumseh engines.
For some reason i assumed the spark plug wasnt directly above the valves like that. Thanks for the video.
Thanks, I'm glad you liked it.
I highly recommend lubricating spark plug hole if you have an issue starting, let it soak in penetrating oil it will free it up
Love it, I have a john deere that had been sitting for a while and did start up and ran but every now and then would start smoking and finally will not start. I am thinking its just what you are talking about.
There's a good chance if it feels like there is very little compression after it dies. If the smoke is black it could be flooding the engine with gas. Then it would be a carb issue.
thanks for the video very helpful
I'm glad it was helpful.
Great advice thanks-wish I would seen this video 15 years ago. lol
This is a jedi engine trick my boy.
You just saved the galaxy👍
Very nice! Good tips!
Great video. Very helpfull, keep it up
I'm glad it was helpful.
Good video. Never really thought of doing that. I will defiantly try that trick.
Alan Williamson Hey Thanks.
Thanks for the info
Learned something today! Tnx
You bet!
Well done. Thanks!
Thanks for watching!
Moe, what is the minimum compression on a 6.5 Tecumseh?
Thank you
I bad spring is rare. It is more than likely just the valve stem sticking from carbon buildup. Make sure you're rotating it as well as moving it up and down. Try a couple types of lubricant and/or even carb cleaner to dissolve whatever is holding it up.
Thanks a lot .
Smart tip on putting you machine away for long periods . . .park the piston on the power stroke so no moisture will enter through the valves . . .I like that!
Thanks for watching.
Thanks, thought I was going to take the head off!
Hey Thanks. I must have too much time on my hands if I'm playing with animations in my videos.
Thanks Moe
Thanks for sharing!
Thanks.

Good tip, thanks
Thanks, I hope it helps.
i have this exact engine on a yard edger, and i have already forced it down with a screwdriver a few times, then put liquid wrench in there, then forced it down a few more times, then it kind of slipped off of my to-do list. as i was walking around bored yesterday i popped off the spark plug and it was still sticking after soaking for a few weeks. i am pretty sure the valve spring is screwed, or mabey the lifter?
Marvel Mystery oil works the best for this.
It should have a spring, washer and oring on it. These all keep it from vibrating in-out.
Here's a good question. I have a tecumseh powered MTD snowblower, and it likes to vibrate the mixture screw on the carb out after a bit. I can fix it temporarily by super gluing the screw in place once I get the mixture set perfectly, but eventually the vibrations break the glue joint and it goes lean anyway. Really frustrating, especially when it happens halfway through snowblowing the driveway.
Thanks Buddy, almost same motor with same problem, I subscribed to your channel
Awesome. I'm glad you liked it.
sixtyfiveford but mine a 8hp n looking in the spark plug hole, looks like 3 valves moving,, is that correct?
thanks great video......
I'm glad it was helpful. Thanks
Thanks for the great vids. I will try this on my briggs and Stratton pressure washer tomorrow but don't know if it'll work. Thee
The engine runs sweet for 5-10mins then stops and won't start again until it's gone cold. Could it be something other than a sticking valve?
Atb and keep up the great vids. I feel like I'm back at school but this time I'm enjoying it.
thanks a million WE are getting 15 to 20 cm. dumps of snow here..I have an 70s Canadiana snowblower with a briggs and stratton engine .. Back fires ,,,sputters.and stalls under load ..Im hoping the valves are just sticking
Carb would be my first look with those symptoms, followed by a spark plug.
