off topic question sir, what other probable cause for engine to die when under load? but runs half choke..already clean na carb jet, adjust the valve, changed spark plug, changed fuel, cleaned air filter... it runs fine when not under load (unchoked)...thanks keep up the great videos BTW
Mr. Steve, love your content, thank you for the information. I'm trying to send some President's Choice Light money, but I'm caught in a PayPal security challenge loop. I'll keep tryin', brother.
Had close to the same scenario with an old auto tech I worked for. We both raced dirt track cars. He was adjusting the valves the same way you do, but due to the overlap of a race cam, the lifters are NOT on the base circle of the cam. It takes longer, but I always use the "exhaust just starts to open, adjust intake", "intake Almost closed, adjust exhaust". He was amazed how loose his valve lash was once he tried it my way. Many thanks to my grandpa that taught me that 45 years ago.

I learned how to adjust valves on small engines at my dads lawnmower shop when I was 12 . He owned the the store for 9 years, best time of my life! That was many years ago and I wish I was back there now
I used to do this on vehicle engines. Put your finger over the sparkplug hole, when the pressure builds, you can feel and hear it. Now watch the piston. Thats TDC. A must know when working on any four stroke engine. Great video!!
Wow, hard to believe a mechanic would not know the positions of cylinder on a 4 stroke motor. I could see an amateur making this mistake. I usually plug the spark plug hole with my finger to make sure I am on compression stroke as it will build up pressure in the cylinder. Easy to feel with your finger or thumb covering the top of the spark plug hole. Love the vid though brother. Well done and to the point quickly.
Learned this in grade 7 shop class. Right before teach got someone to hold spark plug wire and block while he turned flywheel ;-) Imagine doing this today. Suck squeeze bang blow.
Love it Steve. Also worth mentioning is to only adjust valves on a COLD engine. Some pushrods are steel and will expand when hot. They need to be cool to get the proper adjustments.
Steve. The generator looks just like mine. I’ve taken mine into a Honda repair shop after leaving gas in it for over a year. I usually run it out of gas but got side tracked and had to bout it away. Out of sight out of mind. Since I only use it for emergency I thought I ought to check it by starting it up. Well it wouldn’t start. Honda guy rebuilt the carb. So I put gas stabilizer in and always run it out of gas. Even better I have no gas in the tank. I eventually installed a tri-fuel addition. So it runs on NG, propane, or gas. I check it out on NG. I’d love to see a carb rebuild video especially for a Honda like you have there, what to carry as spares in case, and how to long term store. This video was excellent. Even though I know, it’s always good to have a reminder. Thank you sir. Oh, I’m in Las Vegas an temps that get extreme make storing gas near impossible so propane is better.

Very valuable, time saving, bit of information, thanks Steve. Finally getting back to the B&S 5000w generator. With my being memory challenged due to a major head injury I am re-watching all your pertinent videos. You are the best! I love all your closeups on specific details that prevents any misunderstandings. Thank you for the time and effort you put into all your videos.
Head injuries are nasty things. I was assaulted and just stopped working on things for a couple years. When I wanted something to try to get the brain working again, but not too much frustration or challenge,I began to tinker with my old mowers hoping the mechanical activity would help jump start new neurological connections. I have been told since that it's a great plan. It seemed to help me.
Another awesome production! Not only are you a master mechanic you are also a MASTER educator! I have no idea what the "best" channel on RUclips is and never will, but Steve's Small Engine Saloon is right there among the top contenders. Thank you!
I've only adjusted valves a handful of times on my Stihl tools and once or twice on a small 800w 4 stroke generator, but I started wondering about this exact thing yesterday when I took the valve cover off a 2500w scrap generator I've acquired. Great to have it confirmed that which stroke it's TDC on is crucial to correct adjustment!
Great 👍 video Steve!! The way I adjust valves is not TDC... I do exhaust open, adjust intake.. intake open adjust exhaust. I hasn't failed me yet. I also do Stihl the same way with the special TOOL. Thanks again STEVE!! Keep the great videos coming!!! You r tha man!! Still would love a shop tour video, as we are reorganizing our parts department.
Hey Steve, I just wanna say thanks for all the FREE information. I've been an automotive technician for over 15 years and recently was laid off from my job because of the virus at a Ford dealership. I took a new line of work in small engine repair. I always knew the fundamentals and how they worked overall but your videos have shown me those things, those little details one only learns from years of hands on experience. Thanks bud!
STEVE: Great videos. I am 67 years old and have been doing this for almost 60 years. I have a couple of observations. First until the most recent power plants, Engines the valves were in the block and were only adjusted during an overhaul / rebuild by grinding the base of the valve stem. This might not have been apparent to an old timer. I was also a VW mechanic during the "Air Cooled Bug" era so I bring some other experience to the table. Second A very important thing to know is that TDC is not a good place to adjust the valves because by doing so you run the risk of being up on the "COMPRESSION RELEASE" device. If this is done the Exhaust valve will be loose and the compression release will not work causing the engine to crank over very hard and my lock up the starter motor or pull the starter cord from your hand very aggressively. I would watch the valves especially the exhaust valve rocker for the valve lift from the compression release then just past that I would make the adjustments. Keep up the great work. The Zama carb. adjustment video made my weekend! David In Jamestown RI
Yep. On these small OHV engines I adjust lash just past TDC which is the power stroke. This way I'm absolutely sure it's not on the compression release. There's no need to look at the piston through the spark plug hole.
I don't understand why Steve didn't give you a like and skipped right over your comment because you are 100% correct. I am 63 and your comment is absolutely correct. I know that this has been 3 years ago, but I wanted to point out that you sir is right :)
Yes sir. The Briggs manual states before valve adjustment to first place piston TDC on the compression stroke then move the piston down the bore 1/4" past TDC to ensure the tappet is not resting on the compression release ball.
I have run across cases like this, they were either very lucky to hit TDC on the compression stroke on first try or had to make several tries to get valve adj. You opened the eyes of many, thanks for showing this important step..
Thanks Steve! Just last week I went thru at least 10 videos on Adjusting Valves and none of them mentioned TDC on the compression stroke. What a great video! How about a series of neat tips for newbies like this one. Or how about "10 small engine secrets they never told you". It's the little details like this that really make you the goto guy. Thanks Steve!
Excellent insight. Other videoss only refer to TDC - without specifying which stroke (Compression/ Exhaust). I had not considered the importance either way... Thank you for saving me the time and frustration of having to do it over!
Who knew that something as simple as specifying the stroke could make such a big difference? Glad I could save you from the frustration of doing it all over again!
Some mechanics prefer to do their adjustments on the "rocking" principal, ie: when one valve is fully open adjust the other opposing one, and vice versa, both methods work, but lobes on most cams are opposite each other, I'm slightly surprised Steve didn't mention this, as I'm quite sure he knows it. Thumbs up still.
I didn't know this a few years ago (because the videos I watched didn't mention it.) when I adjusted the valves on a Craftsman (19hp B&S), so the mower was parked and replaced. Watching some again because I just bought a 2nd hand walk-behind with the same symptoms (Lol, and "exact" same engine as the rider I parked.), but needed to rule out a couple other possibilities. Good thing I held on to it because I now have electric-start for the use-to-be pull-start walk-behind. Since parking I did learn about the compression stroke, but I wanted to stop in to like/comment/share your video because this video would have helped me out years ago.
Thank you for this video I'm going to adjust my valves soon this is good to know. I have work on small engines a lot but never have had a OHV engine on a lawnmower engine before.
Taryl covers this very subject in many of his video's (also a great youtuber just like yourself) , tdc isn't necessary to adjust valve backlash accurately , just adjust the valves individually making sure to be at the lowest portion of (the round) part of the cam not the peak . I have been doing it this way also and my engines run great.
I feel the same way. It might take me longer to get a job done if I have to teach myself what I need to know, but at least I’ll learn something and do it right. I can’t do everything myself but that’s only because the tool I need might be really expensive. There’s only been a few times I’ve hired someone and only 1 time has it not reaffirmed my do it myself attitude
I didn’t know and as a hobbyist small engine mechanic who does small jobs on the side I’m glad up until this point I’ve only worked on 2 strokes. I have bought the materials to adjust the valves on my old Honda mower and my Stihl backpack blower and I’m glad you put this video out or one of them would have gotten possibly damaged as a result of my ignorance. Thanks Steve!
Great information. Was beginning to adjust valves on my Kohler 18 hp. I knew about TDC but now making sure I'm on the compression stroke for adjustments. Again, very valuable information. Just love your videos...keeps one out of trouble!!
I serviced my stihl fs90 trimmer by myself because you helped me to learn how to do it, and saved some money 😊 Adjusting the valves properly was one of the big things i did and rly thanks for your tutorials... Keep the good work!!!
I have gotten a 4 stroke engine which the previous owner could not get it started once it was reassemble after overhaul. He had timed the engine to the wrong stroke. When I set valves, I just turn the engine to the point where the intake is fully compressed, then adjust the exhaust. Then turn some more until the exhaust is fully compressed, set the intake. I mostly work on 4 and 6 cylinder engines so this saves some time. These are old engines of course, before hydraulic lifters.
People....EVERY four stroke engine needs to make TWO revolutions of the crankshaft to complete its cycle. (This applies to cars as well) A TWO stroke engine only requires ONE revolution of its crankshaft for its full cycle. Best of wishes to all.
@@OOOOOO12345 A four cycle diesel engine is the same. large automotive diesels use hydraulic lifters, which are basically self-adjusting. The small single cylinder 4-cycle diesel engines on portable equipment are the same as gasoline engines. The advice given in this video is still valid.
@@vincentrobinette1507 Actually most larger diesel engines have manual lash adjusters, they have a valve lash adjustment interval called out in their maintenance schedule. The GM 6.6 duramax also has manual lash valve adjusters.
You just solved a problem with a generator I got. (I did not know about this) Been working on stuff for many years too.....Thanks Steve. Really like the channel, hope you keep going.
It amazing how many times that mistake gets made. My procedure is to turn engine until intake valve is fully compressed, then adjust exhaust valve. Then turn engine until exhaust valve is fully compressed, then adjust intake valve. No fiddling with finding TDC. :-)
Find where the valves " overlap" then turn the crank one full turn.. it doesn't have to be right on TDC, just can't be on the intake or exhaust stroke.
I'm going to adjust the valves on my generator motor tomorrow, for the first time ever. I ran out of daylight today. I would not have known the difference. I watched the Champion video on how to do it, but it said nothing about checking to make sure the valves were loose before you start. Your title of the video saved me.. I figure if a mistake is to be made, I will make it every time! Thanks!!
Hey Steve, I've been watching your videos for a while now and they've been super helpful for me. I know a lot of work goes into making these and I hope you keep it up, so I decided to chip in a little beer money for you on paypal. Cheers buddy!
Steve, I'm smiling. Been setting valves 10years and never thought of what TDC cycle I'm at. I don't look at piston I hold the rockers to find TDC . LOL
I really enjoy watching your videos Steve their brilliant for someone like me being informative as well as giving the confidence to have a go at jobs myself 👍🏻
This guy is spot on. You do have to make sure you are checking valves at top dead center on COMPRESSION stroke. You can also watch the valves move as you rotate the engine and the intake valve opens during the intake, closes at the end of the intake stroke, and stays shut until it's at top dead center. EXCEPTION: Some engines have compression realeases, which open the intake valve a very tiny bit during the compression stroke. It will close again before top dead center. DO NOT check the valves until top dead center when the valve is supposed to be fully closed.
You can always find the compression stroke by putting your thumb on the spark plug hole while you’re rotating the engine by hand. The compression will blow your thumb away from the hole as you approach TDC
Thanks Steve for this tip. Adjusted my valves and no compression on my snow blower. Rotated to the compression stroke and adjusted again and she runs like a champ now. !!
I made that mistake and it was on a eu2000i ... i ran it that way for a few hours until i realized my mistake. So i took it apart to see if anything was damaged and the cam on the timing sprocket had worn severely in that short amount of time but i decided to leave it and just correct the valve mistake and to my ongoing amazement it has run almost 10hrs a day for almost 4!/2 yrs with the only thing needing replacing other that plugs and oil was the coil. There is no loss of power and it always starts first pull pretty much. A truly amazing little generator!
There is something to be said for growing up in an era when things got both built and fixed or you did without. If you are out of the country and parts are six months away, you have a very different approach to most things you buy... can it be fixed. So, I said it was on the wrong TDC and my wife asked how I knew. Was it model engines, the lawnmower, jeep, truck, my Dad? Thanks for the trip.
Steve thanks for this video because I'm one of those that didn't know that, I thought that it didn't matter on what stroke for turning the valves as long the piston were TDC, thanks again
No thank you, you are my inspiration to try to get out there and try to work on small engines myself. I need to get ahold of a junk carb so I can look into it and maybe try to rebuild it to see if I can. Love your videos keep them coming I look forward to watching more
Good advice. If it's not on the compression stroke, it's on the intake/exhaust valve overlap TDC point. You're right that the engine would probably run but there would be quite a bit of valve clearance with a lot less lift on both the exhaust & intake valves. It was a good move on your part to not have to work with that inexperienced mechanic any more.
I didn't know the TDC had two different strokes either, but I'm not a small engine repair guy who made any valve adjustments. I'm learning and thanks for this critical tip.
Yeah, I maintained a snow blower before winter and checked everything including running it. Got the call during our biggest snowstorm of the year saying it won't start. I determined the valves were too tight and adjusted them while my fingers were turning blue. No complaints after. : )
I had to stop working on engines in the cold like that. I did it too many times and damaged the circulation system in my hands. Now when they get cold, they do not function. Funny thing is my father did the exact same thing only he damaged his from ice fishing. After that ,when exposed to the cold his hands would turn ash grey and stop working. Thats me now. Too many years working on snowmobiles without gloves in sub zero Temps.
Glad I randomly checked this video. I knew that when I adjusted them but went to double check them and was thinking why are they so tight and completely forgot about that part. So now I’ll double check and they are probably good.
If you remove the plug, there will be no compression. The best way, is to put a finger over the spark plug hole, and turn the engine until air blows out between the head and your finger. You will know for sure, that it's on the compression stroke, as the piston moves to TDC. With an open spark plug hole, it's hard to tell weather its on compression or exhaust stroke.
@@andreboy1 He didn't mention placing his finger over the hole, to feel the compression. If he's relying on the feel of the pull cord, he won't feel anything, except maybe, the valve springs. That would almost ensure he's on the top of the exhaust, rather than the top of compression. Who knows: maybe that was implied.
As a Mobile Small Engine Mechanic, I didn't realize this until 6 months after I started! Maybe I need to find a Community College Class to refine my knowledge. But, after 8 Spinal Surgeries, I am out of the business, but still have 3 dedicated Customers for whom I Season their Equipment every Spring & Fall.
Great way to know your on the compression stroke is to put your thumb over the sparkplug hole when turning it over. If it blows, it's on compression stroke.
When I buy any fuel powered machine, I always spend the extra for the official factory service repair manual. The one for the EU200i was $35 but way worth it. Years back I attended a six week factory sponsored outboard motor refresher class and EVERYTHING was done off the manual. It's just a habit of mine and I know there're on line but call me old fashion. Thanks for this video. I subscribed. Stay safe everyone.
Thank you very much for sharing with us. I'm preparing to do this for the first time on Champion generator. Never attempted this before. Your video has help me understand greatly!!
You made a very good point. I actually didn't think of this myself until you mentioned it. I can say now my generator runs awesome. Couldn't figure out what I was doing wrong. Not a one to let small things get to me but finally started trying to get specs and couldn't get any info. The info that I did get was completely wrong, but after watching your videos I was able to effortlessly get my generator that is an older one running. Thank you for those videos.
I was an ASE automotive technician and this was one of the questions asked in a test. I was the youngest one there and the ONLY one to get the answer correct.
most mechanics that non mechanically inclined people go to do not know much. Why do you think I started watching car repair videos on RUclips? I got sick of paying someone LOTS of $ to do a crappy job. Now I do all my own car repairs/maintenence boat maintenence and small engine stuff too.
Harry Rembe most of the time its not economical anymore. Especially a shop that wants to get a job done quick as possible. Now, doing it yourself, yes can save some money rebuilding stuff. I picked up some junk mowers today to fool around with and see what I can learn.
@@StevesSmallEngineSaloon do you have a video showing how to adjust the valves on a generic Gen with the rocker arm push rod style OHV. not the standard type shown in your video
I had an issue on an OHV motor on a snowblower. Seemingly one of the rocker arm bolts worked it's way loose. Motor was still running but poorly. Once retightened the nut on the stud and checked the other valve rocker nut/stud. Haven't had an issue since. We've had the unit since brand new it was a unit from Sears/craftsman.
@@StevesSmallEngineSaloon I have to admit, I did get a chuckle out of that. It was almost, "I'm not going to mention Timmy's name, ..." By the way, I never realized there are two TDC's, either. I understand 4 strokes, as I'm sure Timmy does, and I've watched valve clearance measurements many times, but until today, never actually heard anyone spell it out -- two TDC's. Of course!
The key word is 4 strock! I actually knew what you were talking about. Actually first experience was a 230 Chevy engine rebuilding. Putting the disturber in 180 degree off.
I have watched a couple of videos by other mechanics and none of them mentioned this. I will be adjusting the valves on 2 different mowers soon and wouldn't have known the difference. Thank You.
I'm coming up on my fifth season in small engine repair business. I was never really completely sure until watching this video. It was always a bit of a mystery. I knew there were 2 top dead centers. I had to turn the flywheel a number of times to try to figure out which was the compression stroke and which was the exhaust stroke. Thanks to your video, now I will know immediately. No more guessing. In my last 4 years, I have probably addressed it a dozen valves. Frequently, I would sit there and always wonder if I adjusted the valves on the crack stroke. I figured that I must have because the engine always ran well and I'm started well afterwards.

Another awesome production! Not only are you a master mechanic you are also a MASTER educator! I have no idea what the "best" channel on RUclips is and never will, but Steve's Small Engine Saloon is right there among the top contenders. Thank you!
Wow, thanks!
I've only adjusted valves a handful of times on my Stihl tools and once or twice on a small 800w 4 stroke generator, but I started wondering about this exact thing yesterday when I took the valve cover off a 2500w scrap generator I've acquired. Great to have it confirmed that which stroke it's TDC on is crucial to correct adjustment!
Great 👍 video Steve!! The way I adjust valves is not TDC... I do exhaust open, adjust intake.. intake open adjust exhaust. I hasn't failed me yet. I also do Stihl the same way with the special TOOL. Thanks again STEVE!! Keep the great videos coming!!! You r tha man!! Still would love a shop tour video, as we are reorganizing our parts department.
Hey Steve, I just wanna say thanks for all the FREE information. I've been an automotive technician for over 15 years and recently was laid off from my job because of the virus at a Ford dealership. I took a new line of work in small engine repair. I always knew the fundamentals and how they worked overall but your videos have shown me those things, those little details one only learns from years of hands on experience. Thanks bud!
Nice work!
STEVE: Great videos. I am 67 years old and have been doing this for almost 60 years. I have a couple of observations. First until the most recent power plants, Engines the valves were in the block and were only adjusted during an overhaul / rebuild by grinding the base of the valve stem. This might not have been apparent to an old timer. I was also a VW mechanic during the "Air Cooled Bug" era so I bring some other experience to the table.
Second A very important thing to know is that TDC is not a good place to adjust the valves because by doing so you run the risk of being up on the "COMPRESSION RELEASE" device.
If this is done the Exhaust valve will be loose and the compression release will not work causing the engine to crank over very hard and my lock up the starter motor or pull the starter cord from your hand very aggressively. I would watch the valves especially the exhaust valve rocker for the valve lift from the compression release then just past that I would make the adjustments. Keep up the great work. The Zama carb. adjustment video made my weekend!
David In Jamestown RI
This advice is spot on!!!
Yep. On these small OHV engines I adjust lash just past TDC which is the power stroke. This way I'm absolutely sure it's not on the compression release. There's no need to look at the piston through the spark plug hole.
I don't understand why Steve didn't give you a like and skipped right over your comment because you are 100% correct. I am 63 and your comment is absolutely correct. I know that this has been 3 years ago, but I wanted to point out that you sir is right :)
@@TimsToolTime-bx1esq
Yes sir. The Briggs manual states before valve adjustment to first place piston TDC on the compression stroke then move the piston down the bore 1/4" past TDC to ensure the tappet is not resting on the compression release ball.
I have run across cases like this, they were either very lucky to hit TDC on the compression stroke on first try or had to make several tries to get valve adj. You opened the eyes of many, thanks for showing this important step..
Thanks for sharing
Thanks Steve! Just last week I went thru at least 10 videos on Adjusting Valves and none of them mentioned TDC on the compression stroke. What a great video! How about a series of neat tips for newbies like this one. Or how about "10 small engine secrets they never told you". It's the little details like this that really make you the goto guy. Thanks Steve!
You're Welcome...
Excellent insight. Other videoss only refer to TDC - without specifying which stroke (Compression/ Exhaust). I had not considered the importance either way... Thank you for saving me the time and frustration of having to do it over!
Who knew that something as simple as specifying the stroke could make such a big difference? Glad I could save you from the frustration of doing it all over again!
I am so grateful that I saw this little bud very important difference.
Right on
Didn't know about the TDC on the compression stroke but thanks to your video, now I know. I am not a mechanic but just love to learn stuff.
Some mechanics prefer to do their adjustments on the "rocking" principal, ie: when one valve is fully open adjust the other opposing one, and vice versa, both methods work, but lobes on most cams are opposite each other, I'm slightly surprised Steve didn't mention this, as I'm quite sure he knows it. Thumbs up still.
I didn't know this a few years ago (because the videos I watched didn't mention it.) when I adjusted the valves on a Craftsman (19hp B&S), so the mower was parked and replaced. Watching some again because I just bought a 2nd hand walk-behind with the same symptoms (Lol, and "exact" same engine as the rider I parked.), but needed to rule out a couple other possibilities. Good thing I held on to it because I now have electric-start for the use-to-be pull-start walk-behind. Since parking I did learn about the compression stroke, but I wanted to stop in to like/comment/share your video because this video would have helped me out years ago.
You do a great job Steve and really help a lot of people. Keep those videos coming!
Thanks, will do!
Thank you for this video I'm going to adjust my valves soon this is good to know. I have work on small engines a lot but never have had a OHV engine on a lawnmower engine before.
Glad to help
thanks steve great vid. what an easy way to find top dead center on compression stroke thanks again
You're Welcome...
Taryl covers this very subject in many of his video's (also a great youtuber just like yourself) , tdc isn't necessary to adjust valve backlash accurately , just adjust the valves individually making sure to be at the lowest portion of (the round) part of the cam not the peak . I have been doing it this way also and my engines run great.
Mechanics like Timmy are why I don't trust mechanics. If I want my engine messed up, I'll do it myself for free.
Fine. Get Timmy to fix your lawn mower.
I feel the same way. It might take me longer to get a job done if I have to teach myself what I need to know, but at least I’ll learn something and do it right. I can’t do everything myself but that’s only because the tool I need might be really expensive. There’s only been a few times I’ve hired someone and only 1 time has it not reaffirmed my do it myself attitude
Been forced to do the same.
Lol
@@oldoldpilgrim7898 🤣
I didn’t know and as a hobbyist small engine mechanic who does small jobs on the side I’m glad up until this point I’ve only worked on 2 strokes. I have bought the materials to adjust the valves on my old Honda mower and my Stihl backpack blower and I’m glad you put this video out or one of them would have gotten possibly damaged as a result of my ignorance. Thanks Steve!
You're Welcome...
Great information. Was beginning to adjust valves on my Kohler 18 hp. I knew about TDC but now making sure I'm on the compression stroke for adjustments. Again, very valuable information. Just love your videos...keeps one out of trouble!!
Glad it helped
You the man Steve. Most mechanics don't want to show you ANYTHING.
Right on
I serviced my stihl fs90 trimmer by myself because you helped me to learn how to do it, and saved some money 😊
Adjusting the valves properly was one of the big things i did and rly thanks for your tutorials... Keep the good work!!!
Great to hear!
I have gotten a 4 stroke engine which the previous owner could not get it started once it was reassemble after overhaul. He had timed the engine to the wrong stroke. When I set valves, I just turn the engine to the point where the intake is fully compressed, then adjust the exhaust. Then turn some more until the exhaust is fully compressed, set the intake. I mostly work on 4 and 6 cylinder engines so this saves some time. These are old engines of course, before hydraulic lifters.
People....EVERY four stroke engine needs to make TWO revolutions of the crankshaft to complete its cycle. (This applies to cars as well) A TWO stroke engine only requires ONE revolution of its crankshaft for its full cycle. Best of wishes to all.
You're exactly right: This video applies to ALL 4 cycle engines, not just small engines!
@@OOOOOO12345 A four cycle diesel engine is the same. large automotive diesels use hydraulic lifters, which are basically self-adjusting. The small single cylinder 4-cycle diesel engines on portable equipment are the same as gasoline engines. The advice given in this video is still valid.
@@vincentrobinette1507 Actually most larger diesel engines have manual lash adjusters, they have a valve lash adjustment interval called out in their maintenance schedule. The GM 6.6 duramax also has manual lash valve adjusters.
@@OOOOOO12345 If it is a four cycle engine, it is just diesel powered, therefore it requires two revolutions as well.
You just solved a problem with a generator I got. (I did not know about this) Been working on stuff for many years too.....Thanks Steve. Really like the channel, hope you keep going.
Happy to help my friend!
It amazing how many times that mistake gets made. My procedure is to turn engine until intake valve is fully compressed, then adjust exhaust valve. Then turn engine until exhaust valve is fully compressed, then adjust intake valve. No fiddling with finding TDC. :-)
You get the Nobel Peace Prize
Same here...works like a charm!
Find where the valves " overlap" then turn the crank one full turn.. it doesn't have to be right on TDC, just can't be on the intake or exhaust stroke.
Both rocket arms were tight on this video, he's got it better
I do the same thing.
I'm going to adjust the valves on my generator motor tomorrow, for the first time ever. I ran out of daylight today. I would not have known the difference. I watched the Champion video on how to do it, but it said nothing about checking to make sure the valves were loose before you start. Your title of the video saved me.. I figure if a mistake is to be made, I will make it every time! Thanks!!
You're Welcome...
Hey Steve, I've been watching your videos for a while now and they've been super helpful for me. I know a lot of work goes into making these and I hope you keep it up, so I decided to chip in a little beer money for you on paypal. Cheers buddy!
Thank You...Right on Jimmy...
Steve, I'm smiling. Been setting valves 10years and never thought of what TDC cycle I'm at. I don't look at piston I hold the rockers to find TDC . LOL
I really enjoy watching your videos Steve their brilliant for someone like me being informative as well as giving the confidence to have a go at jobs myself 👍🏻
So nice of you
Steve's Small Engine Saloon ironhorse 07
This guy is spot on. You do have to make sure you are checking valves at top dead center on COMPRESSION stroke. You can also watch the valves move as you rotate the engine and the intake valve opens during the intake, closes at the end of the intake stroke, and stays shut until it's at top dead center. EXCEPTION: Some engines have compression realeases, which open the intake valve a very tiny bit during the compression stroke. It will close again before top dead center. DO NOT check the valves until top dead center when the valve is supposed to be fully closed.
You can always find the compression stroke by putting your thumb on the spark plug hole while you’re rotating the engine by hand. The compression will blow your thumb away from the hole as you approach TDC
Good point!
Thanks Steve for this tip. Adjusted my valves and no compression on my snow blower. Rotated to the compression stroke and adjusted again and she runs like a champ now. !!
Nice work!
I use my thumb on the spark plug hole as I roll the engine to feel for compression on the compression stroke. Thanx for the video, you made me laugh.
That's because you're smart.
@@acetech9237 The subject was well done with a bit of humor, liked iit.
I made that mistake and it was on a eu2000i ... i ran it that way for a few hours until i realized my mistake. So i took it apart to see if anything was damaged and the cam on the timing sprocket had worn severely in that short amount of time but i decided to leave it and just correct the valve mistake and to my ongoing amazement it has run almost 10hrs a day for almost 4!/2 yrs with the only thing needing replacing other that plugs and oil was the coil. There is no loss of power and it always starts first pull pretty much. A truly amazing little generator!
Appreciate these videos man, you've saved me a few bucks and headaches, clicking like is the least I can do in return.
Thank You...
Steve, you are Mr Saturday night! Better entertainment than what's on TV. More fun, more educational. Keep up the good work! Respect from me in the UK
Wow, thanks!
There is something to be said for growing up in an era when things got both built and fixed or you did without. If you are out of the country and parts are six months away, you have a very different approach to most things you buy... can it be fixed. So, I said it was on the wrong TDC and my wife asked how I knew. Was it model engines, the lawnmower, jeep, truck, my Dad? Thanks for the trip.
Steve thanks for this video because I'm one of those that didn't know that, I thought that it didn't matter on what stroke for turning the valves as long the piston were TDC, thanks again
You're Welcome...
I hope that you are
Going to start filming again, I love every single one of your videos.
Thank You...
No thank you, you are my inspiration to try to get out there and try to work on small engines myself. I need to get ahold of a junk carb so I can look into it and maybe try to rebuild it to see if I can. Love your videos keep them coming I look forward to watching more
I understand which TDC for adjustment of valve . Tanks good teaching.
Glad it helped
Good advice. If it's not on the compression stroke, it's on the intake/exhaust valve overlap TDC point. You're right that the engine would probably run but there would be quite a bit of valve clearance with a lot less lift on both the exhaust & intake valves. It was a good move on your part to not have to work with that inexperienced mechanic any more.
Steve great video I didn’t know how to set my valves on my mud motor for my boat. Thanks
You're Welcome...
Hey Steve now what do you think about setting the lash off the cam on a V twin vanguard 35hp with performance upgrades vs. Off the piston on TDC?
I didn't know the TDC had two different strokes either, but I'm not a small engine repair guy who made any valve adjustments. I'm learning and thanks for this critical tip.
You're Welcome...
Hey! No glass breaking at the tail end of the intro!? It’s always one of my favourite parts, Steve!
Yeah, I maintained a snow blower before winter and checked everything including running it. Got the call during our biggest snowstorm of the year saying it won't start. I determined the valves were too tight and adjusted them while my fingers were turning blue. No complaints after. : )
I had to stop working on engines in the cold like that. I did it too many times and damaged the circulation system in my hands. Now when they get cold, they do not function. Funny thing is my father did the exact same thing only he damaged his from ice fishing. After that ,when exposed to the cold his hands would turn ash grey and stop working. Thats me now. Too many years working on snowmobiles without gloves in sub zero Temps.
I Learned something in this video thanks.
Glad to hear it!
Good call Steve many people don’t know this ,glad you set the record straight
Thank You...
I bet he was drinking the wrong beer. Steve you need to set a beer chart on the correct beer for the job!
hahahahaha Blair has it right Steve !!
You are a Treasure, Steve. Thank you so much for all you do.
Stay gold.
Thank you kindly
‘Timmy’ didn’t have the wrong beer, he had too many 💥🍺💥
Glad I randomly checked this video. I knew that when I adjusted them but went to double check them and was thinking why are they so tight and completely forgot about that part. So now I’ll double check and they are probably good.
Good luck!
Just to be sure I take the plug out and turn the engine slowly , when I feel compression , then I get the engine on TDC.
If you remove the plug, there will be no compression. The best way, is to put a finger over the spark plug hole, and turn the engine until air blows out between the head and your finger. You will know for sure, that it's on the compression stroke, as the piston moves to TDC. With an open spark plug hole, it's hard to tell weather its on compression or exhaust stroke.
@@vincentrobinette1507 He said when he "feels" compression just as when you put your finger over the hole. Dumb comment.
@@andreboy1 He didn't mention placing his finger over the hole, to feel the compression. If he's relying on the feel of the pull cord, he won't feel anything, except maybe, the valve springs. That would almost ensure he's on the top of the exhaust, rather than the top of compression. Who knows: maybe that was implied.
Quality tips gets the thumbs up.All your videos get it.this is how to teach people.I'm a mechanic myself and I love your simple smart videos.👍
Wow, thanks!
As a Mobile Small Engine Mechanic, I didn't realize this until 6 months after I started!
Maybe I need to find a Community College Class to refine my knowledge.
But, after 8 Spinal Surgeries, I am out of the business, but still have 3 dedicated Customers for whom I Season their Equipment every Spring & Fall.
Great way to know your on the compression stroke is to put your thumb over the sparkplug hole when turning it over. If it blows, it's on compression stroke.
Nice tip I watch the valves but nice tip
i was gonna say that, you beat me to it!
When I buy any fuel powered machine, I always spend the extra for the official factory service repair manual. The one for the EU200i was $35 but way worth it. Years back I attended a six week factory sponsored outboard motor refresher class and EVERYTHING was done off the manual. It's just a habit of mine and I know there're on line but call me old fashion. Thanks for this video. I subscribed. Stay safe everyone.
Right on Rand! Thank You...
I guess he was just lucky 50% of the time...
Thank you very much for sharing with us. I'm preparing to do this for the first time on Champion generator. Never attempted this before. Your video has help me understand greatly!!
You're Welcome...
Wait until you get a customer who wants you to adjust the valves on a 2 stroke . 🤷🏼♂️😂😒
Maybe it's got a Reed valve
Ya learn something new everyday. Thanks!
Happy to help!
I went through the same thing with compression/exhaust stroke; he wanted to argue so I let him make his own mistake.
You made a very good point. I actually didn't think of this myself until you mentioned it. I can say now my generator runs awesome. Couldn't figure out what I was doing wrong. Not a one to let small things get to me but finally started trying to get specs and couldn't get any info. The info that I did get was completely wrong, but after watching your videos I was able to effortlessly get my generator that is an older one running. Thank you for those videos.
You're Welcome...
Must be a serious topic....no mention of beer.
Thank You Steve for showing the difference in the two T D.C 's !!
Our pleasure!
How the hell can any mechanic not know this? Isn’t this one of the basics?
I was an ASE automotive technician and this was one of the questions asked in a test. I was the youngest one there and the ONLY one to get the answer correct.
RNR 420 there are very few mechanics , there are a lot of parts swappers out there. Me thinks this guy is a mechanic.
@@heknows5418 and the numbers of the latter are growing, l work with several. Rebuild not replace, unless economically not worth it, is my belief.
most mechanics that non mechanically inclined people go to do not know much. Why do you think I started watching car repair videos on RUclips? I got sick of paying someone LOTS of $ to do a crappy job. Now I do all my own car repairs/maintenence boat maintenence and small engine stuff too.
Harry Rembe most of the time its not economical anymore. Especially a shop that wants to get a job done quick as possible.
Now, doing it yourself, yes can save some money rebuilding stuff. I picked up some junk mowers today to fool around with and see what I can learn.
glad i found this page i had no idea about TDC and out of all the video about gens this is the only one.
Thank You...
@@StevesSmallEngineSaloon do you have a video showing how to adjust the valves on a generic Gen with the rocker arm push rod style OHV. not the standard type shown in your video
Oh how I’ve learned the hard way! I triple check for the correct TDC before I adjust valves! Thank you!
Right on
If you did not know that then you probably have no business messing with the valves to begin with.
I had an issue on an OHV motor on a snowblower. Seemingly one of the rocker arm bolts worked it's way loose. Motor was still running but poorly. Once retightened the nut on the stud and checked the other valve rocker nut/stud. Haven't had an issue since. We've had the unit since brand new it was a unit from Sears/craftsman.
Poor Timmy probably dropped in to see what new video his old buddy Steve put up. Now he's crying.
OOPS...
@@StevesSmallEngineSaloon I have to admit, I did get a chuckle out of that. It was almost, "I'm not going to mention Timmy's name, ..." By the way, I never realized there are two TDC's, either. I understand 4 strokes, as I'm sure Timmy does, and I've watched valve clearance measurements many times, but until today, never actually heard anyone spell it out -- two TDC's. Of course!
I thought their were 4 top dead centers for a 4 stroke engine.
@@whitelightning3263 Well, now I'd expect a TDC at the top of two of those 4 strokes, and a BDC at the bottom of the other two of those 4 strokes.
Thats the only reason I havent adjusted my valves on my golf cart.Now I know and THANKYOU so much.
You're Welcome...
180 off,. alot of people get confused with this
A lot of people also don't understand that "alot" is not a word.
He might have mainly worked on 2 stroke engines
Yes, alot of people do get confused with this because it's actually 360 degrees off not 180 :D
50 yr's I've been screwing my valve puchie wrong! Thx Steve
Nice work Steve, amazing the people who work on engines and didn't know that
Indeed!
like the way steve talks, for any layman to understand and gets to the point
Thank You...
A great reminder for all us diy'ers,thanks Steve.😊
You are very welcome
Thanks for posting this video. I am about to do this for the first time and your video saved me from messing up this crucial step.
You're Welcome...
The key word is 4 strock! I actually knew what you were talking about. Actually first experience was a 230 Chevy engine rebuilding. Putting the disturber in 180 degree off.
I knew this and it's been so long I would probably make the same mistake. Thanks for reminding me!
Happy to help!
Very nice, I did not know to check that. I am not a small engine mechanic but I have to deal with them every now and then.
Good luck!
I have watched a couple of videos by other mechanics and none of them mentioned this. I will be adjusting the valves on 2 different mowers soon and wouldn't have known the difference. Thank You.
You're Welcome...
I'm coming up on my fifth season in small engine repair business. I was never really completely sure until watching this video. It was always a bit of a mystery. I knew there were 2 top dead centers. I had to turn the flywheel a number of times to try to figure out which was the compression stroke and which was the exhaust stroke. Thanks to your video, now I will know immediately. No more guessing. In my last 4 years, I have probably addressed it a dozen valves. Frequently, I would sit there and always wonder if I adjusted the valves on the crack stroke. I figured that I must have because the engine always ran well and I'm started well afterwards.
