Almost everyone of these videos on KZread get the exhaust and intake valves backwards. Briggs uses aluminum push rod for intake and steel for exhaust. Very easy to see the color variation in the video. Also just remove intake or exhaust manifold and look to confirm. Both intake and exhaust ports are near topside of head. The intake passage goes down at an angle to bottom valve.

I have the same motor with the same problem, followed your vid and it runs great again. Thanks, you saved me a lot of money.

I have been working on small engines for 40 years and the way to set the valves and it has never failed me, is if one valve is open all the way, then set the other valve, then rotate the engine to open the valve you just set until it is fully open and set the other valve clearance. Try it one time and you will do them all like this, It save a lot of time and guess work.

Great video. Tomorrow I am replacing push rods on a briggs and wanted to double check procedure for adjusting valves. Valve lash moved and threw the rod and bent the crap out of it.

thanks for the video man it runs fantastic now even with a brand new battery would barely moves open up the cover and the valve is loose as hell did my adjust and bam fired right up

thanks a lot! been searching for days an this is the only one that helps

man i used to build car engines, went to school for it. so used to hydraulic lifters i didnt realize this. had a husqvarna mower for years with a 15hp kholer engine, and it had started to get a little finicky to start but ran great. well my blade clutch locked up so i bought another mower today for $125. i planned to use it and some parts off mine. well we got it home and i couldnt start it, same issue. this motor was briggs and neglected. real dirty. well you just saved me a lot of trouble man

TY, i was completely lost and thru trial and error and some google'n.......i needed to try and learn how to adjust my valves on a Briggs and Strat 21hp zero turn. My mower was doing EXACTLY what u said and not turning over but it was working with the plug out. Great video and TY for saving me money!

The intake valve is on the bottom, exhaust valve is on the top.. Aside from looking at the manifolds, Another quick way to tell on these engines is the intake pushrod is aluminum, and the exhaust valve is steel.

right, don't mix them up.

ive found that some times the extra bump on the cam for the compression release gets wore down from use if you adjust the valves correctally and turn over the motor slowly you should be able to see the valve move slightly out then in just before it opens all the way if it dos not its probbaly the cam that needs replaced

good job of explaining the problems with blown headgaskets

TY u saved my ass , didn’t have feeler gage but tightened exhaust and f’er fired right up!

Hey man...nice work. Your video is great! You explain things things very well. I had no idea how to do this. Now thanx to you i believe i can handle it. Thnx again.

Thanks for the really informative video!

the intake valve on single cylinders is located on the bottom and use the alumin rod the exhaust uses a steel rod

Thanks for the immediate response. I did what you recommended and the rod is straight and no other visible signs of wear. Any other suggestions would be appreciated. Thanks.

My new lawn tractor was making a rattling noise, after adjusting the valves, it's quiet! thanks for the video

Fellow youtubes the intake on most these single cylinder intec engines 28 or 31 cubic inch are typic 3 thousand to 5 thousands of a inch for intake and 5 thousand to 7 thousands on exaust there is a special val lash for some 31 cubic inch engines with a Q in there model number [reamber the alum push rod is used on the intake and metal for exaust ] also check your rocker arm studs they can loosen over time causing the valves to go out of adjustment more frequently . Briggs recommends you set your valves every season but this is rarely done in pro shops[rocker arm studs tork at 100 inch pounds and valve covers as well as rocker arm jam nuts tork at 65 inch pounds] if your rocker arm studs are loose use 242 Loctite and apply to the treads that are on the stud to head surface .

Thanks man..... best instructional video on Briggs & Stratton valves.... the push rods came out before I started watching your video.... great what you did. Great instructions... question from a fan.. Which push rod is on the top (intake) the steel or the (maybe aluminum) light one? Also mention that you adjust or check clearance on both intake and exhaust. But really great vidieo... watched it twice and will check out your other videos.

yes when you adjust them correct with the plug out by hand turn over the engine and look at the exhaust valve it should move out slightly like 1-2 mm and back in then out to fully open the valve the lobe can wear down and not open fully causing it to not allow it to crank fast enough or not at all causing the no start or hard start

Thanks so much. Replaced head gasket and would fire, but not start. Re-adjusted valves and it started right up.

the lower valve is the intake with aluminum push rod. my 15.5 hp has the intake on the bottom and the exhaust on top. please check this and let me know. Thanks Ben

Half of youtube instruction videos get that part wrong. It got me confused at first, when my aluminium push rod broke and I was looking on how to fix it. Do your homework before posting videos!!

i havent dug to far into the internals on any motor but i would pull the head on that side and check dose it run and have spark on that side could be a stuck valve or if its a ohv a bent pushrod

thank you for this video. It is a great help. I'm hoping you can help some more. I have readjusted my valves on a 16.5 B&S, twice now, a few days apart. On both occasions I seem to get it to work fine but then after starting the engine a few times it seems to slip out of adjustment. I just readjusted per your advice and tested it with the plug in but wire off and still with the valve cover off. It spun like a top. I was so happy. After I put it all back together I hit starter and it fired. Excited I shut it down and then tried it again. This time it stumbled on the compression, but then kicked over and fired up. great. worried about the stumble I tried it again. NO GO. it stuck just like before adjustment. Any ideas?

Great video and thanks. I have a Briggs and stratt 19.5 intek. Starts fine on initial contact but after motor warms up I don't have the option of shutting her off because she won't refire until completely cooled down. Any advise?

well you can try to fish it out but i would pull the head if i know somethings in the head like that its probbaly wedged between the valve and the head ive never used anything except a philips screw driver to find tdc but when you have the valve cover off its not needed you just have to adjust them when the other is fully open i didnot use anything to fine tdc in the vid

i believe i have oil seeping from my rocker cover gasket. i`m going to change it myself, first time doing this. can i change the gasket and not have to worry about the vales. makes me nervous because i`ve never adjusted valves and really just want to change that gasket and go

remember because when the engine is not running the compression release valve is in the open position, you will have to drop the pistion 1/4" past top dead center or adjusting the intake will be off as much as 0.005 thousands off from where they need to be.

I had this same problem last year. 17.5hp. I did what you did in the video and it worked. No problems all winter snow plowing and cut my lawn about five times this year. Now this year same problem. I adjusted the valves the same way. Still barely turns over. Batt. is fine, valves adjusted to .003, have spark, gas, etc. :-(

Actually i just reset the valves again and got a new battery. No problems now. My battery was 3 years old. Thank you though.

I had a mower guy bust my chops for not setting the valves in my mower, its seven years old. I explained to him that running premium synthetic oil controls the heat and wear more effectively, there is no issues with compression loss. I used to do a lot of L-Head valves that were tight, I would add .001 to the intake and .002 to the exhaust and never touch them again. This setting would boost cylinder pressure and allow for wear.

Thank this will save me money!

First off awesome video, secondly i just did this and my bottom valve was too tight i adjusted to specs for my mower and still the same results. It will start i manually spin flywheel with my hands. Any suggestions

thanks for my first comment from France glad it worked for ya

Briggs ohv engines have a decompression valve on the intake side this allows it to drop a small precent of the compression by opening the intake valve sooner on the compression stroke so the starter can spin the flywheel up to speed.

Ok... If you have adjusted the valves correctly you could have a more seris problem such as came lubes wore down. This means that no mater how many times you adjust it, it wont ever work right with out replaceing the cam. You need to see how much movment the rocker arms move now as for adjustment they are usely set for a twin between 0.004 to 0.006 thousandths of an inch.

Thanks brother. This video is exactly what I needed and fixed mower. Cheers man

Very good video , and informative as well . Thumbs up , mate

I have a honda gx240 8hp with OHV. Its an older pressure washer from 1989. I looked up the specs and intake=.15mm and exhaust=.2mm. The intake valve was already to spec. The exhaust valve tappet was way in, it has no play, no gap or anything. The motor was at TDC. When i put the exhaust tappet at .2mm clearance the engine became difficult to turn over, almost impossible. When i put the exhaust valve back in to where it was it works ok, but is hard to start and runs a little rough. Why is the exhaust valve tappet needing to be pushed way in at TDC?

Thank You. This Video helped out a whole lot.

What gaps did you set the tappets at (in mm if possible)?

i did that on purpose because on some mowers are different and you should go by the manufactures specs but .004 thousands is what i used on both sides

I had what was a compression problem with similar issue as you showed in your video. I adjusted the valves and it started fine and I ran it in the garge for a few minutes.

What's the valves set on a 18.5 briggs stratton huskvanra ride mower

So tweaking the top/intake fixed the lethargic start up. But....the damn exhaust/bottom valve keeps coming loose and the spring seat cap keeps coming off and the engine won’t restart as it needs to be readjusted. Hope it’s not ruined because that bottom push rod sometimes doesn’t even move when I’m turning by hand the piston. Like it’s not seated and then I find TDC + 1/4 turn to .009 clearance...then it runs fine to that bottom valve bounces loose again. May try to go .002 and see

this is perfect mine is the same thanks

Thanks, this helped greatly

I was adjusting my valves and one of the plastic piece broke and I looked in my parts manual and I know its a part number is 1034 and I can't find that part, I was wanting to know if it's ok to run my mower without that plastic piece?

the ohv briggs intake valves are on the bottom and the exhaust is on top of the head smokeing after you worked on the head could be valve cover gasket leaking which is common if you don't replace the valve cover gasket and leaks on to the muffler, or if it is coming out of the muffler then it could be leaking from valve guides blown head gasket or leaking past the rings which means a rebuild in the future. I/C means it is industrial and commercial built with a cast iron sleeve in the cylinder.

Double check method re Valve setting. You should be able to start your engine with some Starting Fluid if your fuel pump is pumping clean fuel and you have no water in carb bowl. Drain and clean carb bowl just a little water will keep it from starting. Are plugs good, cylinder dried of any remnant water droplets. If you have spark, can get it to start, you will know if your valves are correct,

Hi,I have a Craftsman 4 years old Riding mower 21 hp Briggs & stratton engine . Motor hard to turn with starter ,new starter & battery--It make 3/4 turn & if if make 1 to 2 turn start right up. When starter can not turn it heat up ,without Spark plug engine move ok , I checked the valve clearance .004 & .006 -- Do you think it is a Compression release valve ,how I can be sure of that. Please help ,what other thing it could be?

Bent push rods are a good sign of very poor maintance on the owner, this means that at one point the valve starts to hang up and isn't as free as it should be. this could cause bigger problems such as the valve could get stuck in the compressed position and hit the top of the piston or could cause seize to the valve guide and push it out of the way resulting in pushrod failure also. look around the area of the valve spring and check for any discolored like it got hot this means it may have bigger problems.

You gave it gas it look like but It turns over smooth but not catching. The carb is rebuilt new solenoid. can there be any other electrical problems or if it turns and not catching is it most likely the valve? . It was hard to turn over before I took off the starter and replaced the gear and before I put the starter back on, I manually turned the top of the engine till it moved smooth. Once the starter went back on it spins great but still no start.

This will come in Handy for when it comes time to replace the cylinder head on my sisters friends (Smith) Intek lawnmower as she thought she hit a rock when mowing the lawn which means she thought that the key for the magneto pulley sheared off as the backfiring through the carby & exhaust manifold is a symptom of that. I put my finger over the spark plug hole while cranking the engine where I felt absolutely no resistance against my finger, I removed the valve rocker cover only to find out that the valve collet for the exhaust valve had sheared off & the valve had dropped down into the cylinder. When I removed the cylinder head , to my surprise the valve had been pushed through the exhaust port in the cylinder head without any damage to the bottom end of the motor which means the Aluminium cylinder head must have become very hot almost to the point of melting (I have heard of someone in Australia who melted a cylinder head on a Nissan RB30ET engine which was fitted into a Holden VL Commodore,in the 1980's Nissan signed a contract with General Motors Holden to say that legally the turbocharged engine could only be factory fitted into a Holden so the Australian built Nissan R31 Skyline was never fitted with that engine). Yeah , I don't know , she traded in her old lawn mower for the Intek one & paid $1000 AUD for that one when they (the lawnmower shop) could've chased up a brand new Briggs & Stratton engine for the same price & bolted it onto the old one she had which was still good - what was wrong with the old one? My guess is the conrod snapped as she noticed a clunking sound,I thought they were going to rebuild it at the shop,that would've been the other option,I think they fail because I think she probably never changes the oil in it,I have heard of people saying Briggs & Stratton engines are a heap of crap only to find most of them never get an oil change done on them over here. Yeah & I am a Jones! Why is it that I get that a Smith is all like that over here in Australia & they're getting a bad wrap with all of that stuff? (i.e. never looking after things & getting ripped off by dodgy people left ,right & centre !!)

I'm glad I watched your video, since I'm used to the Honda system where the nut functions as a jam nut and the torx equivalent is the actual adjuster. Does your engine have a plastic cam? I'm in disbelief at all the plastic that B and S uses in their engines, like the 6.75 HP on my snapper mower. It has a plastic carb and the only metal pieces are the screws, jet, float hinge pin, one end of needle valve and the throttle/choke plates. The genuine replacement was $40. The starter dogs and assembly are cheap plastic, but B and S does not offer a rebuild kit for this particular model, and it is a newer engine. You must purchase the entire engine cover to get the starter parts. B and S discontinues parts availability too soon and those with their classic engines may have problems finding certain parts if not kept on-hand (like you do with the extra engines), or end up getting Chinese clones, like starters, carbs, magnetos, etc..I just don't have additional room for extra engines and parts. I have a couple of shops around here that have Junkyards with old abandoned equipment I can usually depend on, but the small horizontal shaft engines are always in short supply, like the engine on my edger. Thanks for the information, and I subscribed to your channel. Not too many people even tinker around like we do. I also work on Echo equipment and service my neighbor's equipment, but B and S and Honda/Honda clones are the only two engine types I've owned. Never had a Tecumseh engine because of all the bad s**t my dad would say about them. I also tinker with cars for the past 45 years.
