Thanks Jeff, I was about to throw mine away today(husqvarna lawnmower). Every video I saw was concerning the carb. And mine was perfect. Watched your video, and that was exactly my problem. Saved me $500 and it now runs beautifully. Thanks again for the great video.
I've got a GCV190 on my mower that is very hard to pull. It runs fine, just getting it to turn over is a challenge. I haven't spent much time diagnosing it as I haven't had it long. But I think I know exactly where to look now. Thanks Jeff!
I have a Husqvarna self-propelled AWD that I was ready to scrap. I remembered having a similar issue with valve train on a B&S 21HP on my old John Deere D120. I googled it, to confirm, and found your video. Lo and behold, I have a cracked exhaust rocker arm. I'm going to do the same as you, with the new seal. I found another thread, where the engine guru suggested Loctite 620 on the guide, before driving it back into place. I think I am going to do both. Better safe than sorry. Thank you so much Jeff!
_"They always seem to loosen up a little bit... after you tighten them down."_ Makes sense. The locking nut is pulling the screw outward as you tighten it. Thanks for sharing with us, Jeff.
Thanks for the great vid !, my karcher pressure washer with a honda 190 has been pulling the cord out of my hand for two years and never knew why .Last week i was stripping the stain off my deck in the hot sun(90 degrees) and it finally died, saw your vid and sure enough the exhaust rocker cracked and bent, I.ordered the Honda rockers from Amazon only to realize the pivot pin that holds the rocker was trashed too. I replaced and gapped them and the engine starts easy again and runs great.$25 fix So before you order, check the pivot pins. Thanks so much!
Lightweight is good and what did I use it for it’s a lawnmower ua-cam.com/users/postUgkxTPN04aT-Qdjr_KS3ql7ng8wnU3wwsCqk also recommend Yes it is lightweight so hence not as robust as our old one. But if you take care it does the job really well.
If you look down at the flywheel there is a dowel sticking out. Line that up with the notch in the case where the valve cover mounts. It does not matter if it is compression or exhaust stroke on this engine.
Watch for exhaust guide moving up and stopping valve movement, which breaks the arm, can put the intake valve seal with rubber removed on exhaust and new intake seal installed once guide is driven back down 😊😊😊 It works and will stay put 😊 Thank You 🙏
Engines, stick edgers, weed esters, pressure washers, they all work dandy when consistently used. They all seem to get issues when sitting too long (like over the Winter). Regular use, oil changes, ethanol free gas, and you're golden. Except with pressure washers, I've always had more troubles, not with the engine, but with water pump. It's like $150+ service around here to have it reconditioned. For that price, it just might be time to replace the pump DIY.
Mine was so hard to pull the kickback was enough to pull your arm off. Pulled the valve cover and no crack on the rocker arm, but the exhaust valve did seem like it had too much play in it. So I set the gap to the OE specs, and boy it's like night and day. Pulls with little effort now and starts on the first pull almost every time! Thanks for the help as I was getting frustrated in why this was so hard to pull!
Thanks for a great video. Just a little suggestion, TDC on COMPRESSION stroke. Combustion stroke or Power stroke is downward. Sorry to point that out. Great video . Thanks
Wow man thank you so much you saved us from having to replace a pressure washer! That was a great video well instructed no BS. Thank you very much I greatly appreciate what you did. I had the exact same problem with the exact same exhaust rocker arm and now I know exactly what to do thank you
The reason I’ve cracked my intake valve before is because the guys weren’t practicing proper pump operation paying attention to the pump itself and making sure they always are doing a pressure release after shut off. They’d go to shut it down and wouldn’t release the pressure after shut down and then would not perform one before Pull starting it. They’d just go to pull start it not giving attention to the extreme compression all of the sudden and instead of taking the wand and pulling the trigger to release the pressure they’d just muscle it like they’re kick starting a Harley. You’re only going to make that mistake so many times until the engine or pump or both give up on ya. So yeah it’s real important to release the pumps pressure after shut down and before start up if you want the pressure washer to last.
Nice fix Jeff: I found that if I changed my customers over to synthetic oil that it helps to stop valve seizing on those engines that run hard like on pressure washers. Thanks for the video.
Not in my case. I use Mobil 1 and last week it refused to restart after a long run. Just get one backfire when I pull the cord. I haven't opened it yet (I was here to learn), but I fully expect a stuck valve and/or cracked rocker. This video gives me the confidence to move ahead. Thanks!
I know this is a stupid question but I'm still learning and I don't want to screw this up.... When you spray lubricant before closing everything up are you just spraying WD-40 or is there something more appropriate for engines??
I have got a gcv200 mower, man was that hard to pull start. Just done valve's couple times so not happy. I went to the spark plug first to take out, found that the spark plug was not tightened up, simplest fix.Easy to pull now, starts OK. Not experience at this, I tried the stick method for top dead centre found tricky, I tried small led light in spark plug hole a little better for me.But hey thanks for you help, not to be rushed couple days thinking out is better than couple weeks down shop.
I have a GC190 on my pressure washer vertical version. Upon looking at the valves the intake rocker was really loose. If you adjusted to the .006 the adjusting screw was almost all the way in, not enough threads to install lock nut. Looking for what would cause this? I now have taken the engine apart and ordered new valves and springs. Have not pulled the flywheel off as yet so I have not been able to look at the valve itself.
After tearing it apart it was the valve seat had wobbled enough to come loose from the aluminum block I'm going to try to stake it to keep it in there for future years
Jeff should have let the cover sit for an hr before cranking the piss out of it with his worn out 10mm. That way the body builds up in the sealant. I found that out with my transmission on my Dodge Journey. After I ran it down finger tight I let it sit all night and it sealed up finally tightening it the next morning.
I have a very similar power washer but could not find the model and serial number to purchase the water inlet tube.Could you please tell me what is the model and serial number of your GCV190? Thanks for your help
Thank You for this video also, after I took the cover off I discovered a stuck intake valve. A little soak with WD40 ans a small tap it popped up. Thank You!
I've seen the cracked exhaust rocker on enough of these Honda 160&190's to conclude it's a bad design that too many are suffering from. Honda really should have addressed this by now, or they make a lot of money from selling so many rockers?
Yep, product recall, folks getting hurt from pulling kick back. Put some heat on Honda they can afford to fix their f up. At least offer the part for free. Reputation...
I agree the exhaust valve is not getting enough oil and it’s trying to stick to guide You can count on where the problem is every time and on hundreds of them 😢😢😢
Hey Nice Input. What can it be on a GCV530 a cold start is on point but if the Engine was hard on work and I Stopp it and will do a warm start the Engine turns but no Start in 90% of cases. Compression is 4,2 Zyl 1 and 4,8 for Zyl 2 (6-8Bar) Sparkplugs Ignition Coils are new, carb is clean. Cause my fault is exactly the opposite of yours. With Choke the warmstart works...
@@JeffsLittleEngineService thanks for answer. On weekend i checked the valve and they are in good condition. The cam wheel and decompression works fine. So the last two things are the carb and in worstcase the piston rings
On my gcv 190 the valve guide/seal slide up out of place which caused the valve to lock up. In turn cracked the rocker arm. The valve was not actually stuck or siezed.It could not go down since the guide came up and out of place.
So, those engines do have markings on the cam gear, two little lines that level out horizontally with the edge of the cylinder block (would have been facing down with the orientation of the camera/engine), and the crankshaft has a line/arrow that lines up inside (had to replace the crank on one of these), once those are all lined up respectively you can re-install the timing belt and re-assemble. I am now curious though to check my valves, as I am also having a hard time pulling mine/getting it to turn over. So thank you for this.
Can you confirm that the cam lobe is dead center with the piston at max height? I'm doing mine now but the lobe is off to the left at max height. Does this matter?
I would say that yes it matters, even one tooth off could make the difference between running properly with correct timing and not. Just like how a vehicle would not run properly if it was off a tooth on its timing.
No need for all of that top dead center stuff. You can see the cam lobe right there. All you have to do is set the lash when the exhaust rocker is on the base circle of the cam basically when the lobe is opposite the rocker
So I picked up a craftsman 3000 psi 190cc the pull cord wouldn’t move at all took it and spun by hand nothing it spins halfway smh then stops and sounds like it hits a metal. Took the top nut off sprayed it with penetrating oil and spins good till I tighten the but on and does the same thing. Any idea wat it could be
Hello from Australia🇦🇺. Great video thankyou. Did you wait to let the liquid gasket paste set before starting the mower? Also i have 2x 196cc electric start mowers that are hard to pull start even when they were brand new they were hard to pull. Would it most probably be that the valves were not set very well from factory or could there be other reasons why they feel so hard to pull start?
yes I try to let it dry overnight. Hard starting could be the valves or something else. It is not likely though that they were set wrong at the factory but maybe possible. Thanks for watching
Maybe I'm living better than I thought I was. I tilted the machine to the front in a big was tub and shook it the best I could. lol and behold the nut fell out. Now we'll see if there's any damage.
It actually turned out good, sorta. I reinstalled the locknut, adjusted the valve to spec and it started right up. I ran it a couple times for a total of 30 minutes or so. Later it wouldn't start and appears the exhaust valve is stuck open, not fully closing. I haven't gone back into it yet.
Had the same engine Tuliped an exhaust valve Was hard to start from day one Is there any way to adjust timing on this engine? Timing belt timing was correct
The cam lobe on the one I'm fixing now doesn't match dead center when the piston is at max height. Is this a problem? I know the markings on the underside of the cam match the lobe at center with the cam housing. Mine is off to the left at max height.
Hi Jeff. I bought brand new rockers, I replaced them both, adjust the valves, first rope was fine. After that same story, it's ripping of my hand. Any ideas? Thanks
My exhaust valve was stuck too. I pushed the valve into the cylinder and ball honed the guide. After assembly, it about broke my hand trying to start. After watching this I see the broken rocker arm! What causes the valve to seize in the guide?
I have a 3300 ryobi pressure washer with a GCV190 and so far it's been my worst investment ever. It won't even start now. It did after I cleaned up the carb etc. It was fine yesterday as for starting it up. Only pressure for half a second and then nothing. Left it outside and it rained today, started for about 10 seconds and died. After it started pulled the trigger and 3 small rocks shot out of the gun lol. It's barely 2 years old. Then it got extremely hard to pull, shut off the water and tried and pulled easily. Turned water back on still pulls, just doesn't start. I guess next step is to check the spark plug. I know what you mean about those valve clearances. I did a complete valve adjustment on my 2000 Honda prelude and it sounded better than before. Took me 2 days to do that. I am at a loss with this pressure washer so far.
I have seen the pumps fail and make the engine hard to pull the rope/hard to start. The rocks may have gotten into the pump too.Try using starting fluid to see what happens
This Ryobi pressure washer has oil burning white smoke coming from the pull start after it starts up I stuck a camera down the cylinder and it looks like the cylinder bore has deep gouges from the rings I would thing but I'm definitely getting annoyed by it
Hi you mention in the video you tapped on the valve with a hammer to loosen the stuck value, I’ve had problems on 2 of these engines a had the rockers crack due to valve guide slipping, I think that is what happened to yours. I tapped mine back into place it lasted a little while then slipped again. I’d be surprised if this machine lasted very long before the problem came back as it will slip again. I just swapped the engine in the end. I’ve only had it happen on the 190, the 135 and 160 I’ve never seen it happen on those. Good video.
Pressure washers have a back and forth torque load while in use causing a shock load known as water hammer. This transfers to the crankshaft and ultimately the valve train causing valve springs to be tested to their maximums. The timing belt is rubber and stretches to absorb the shocks. Remember what happened when your feet slipped of the pedals on your bike when you were a kid? Same principle.
Could be that the exhaust valve guide is migrating out of the case, and contacting the rocker arm. I made a video in which I address this issue. ua-cam.com/video/zZz0MRqxGX8/v-deo.html
Gragg Cain if you need an IPL, go to ereplacementparts.com. , there you can see a diagram and find part numbers, and order parts if you want. Great company to do business with, though I think shipping is kinda high. Or shop on the webernet
Why did it get stuck in the first place? I loosened my valve by tapping on it but it still sticks a little but I can push it down. How can I determine the reason for this?
My 190 gcv engine in my pressure washer would not start after shutting it down to move some items in my deck. Checked the fuel system, found no problems so I removed the plug and checked for spark. Had spark. Checked for compression, none. Removed valve cover and noticed about 1/8" gap between rocker arm and valve on the compression side. Noticed the exhaust valve was stuck in and I took a screwdriver and popped it out. There were no cracks in the rocker arm. Don't know if the piston has clearance for the valves or what could have gone wrong or if this thing is worth fixing. Paid extra for the honda engine on the husky washer. Engine only has 40 hrs on it. My mistake.
Carburetor could have flooded and filled the cylinder full of fuel. If this is the case,the rings won't hold all of the fuel in the cylinder,your oil level is going to be high and your dipstick will smell of fuel. The carburetor float valve and or float valve spring are your typical culprits.
Mines been wonderful except I’ve not been able to figure out why my soap ain’t coming out ‘? I’m sure it’s on my end. maybe anyone know. I’m watching your video now just started 🤞!!
Jeff my pressure washer runs but if you let off of the gun handle and stop spraying water it immediately turns off but of you keep spraying after a few seconds it starts smoking and smells like rubber is burning idk what’s going on
Most likely culprit is the unloader valve. This valve circulates water when you release the handle, thereby relieving the load on the engine. Almost every pump uses some form of an unloader valve. This is also a temperature relief valve that exhausts water to the outside world if the water gets hot enough from recirculation.
Thanks Jeff, I was about to throw mine away today(husqvarna lawnmower). Every video I saw was concerning the carb. And mine was perfect. Watched your video, and that was exactly my problem. Saved me $500 and it now runs beautifully. Thanks again for the great video.

_"They always seem to loosen up a little bit... after you tighten them down."_
Makes sense. The locking nut is pulling the screw outward as you tighten it.
Thanks for sharing with us, Jeff.
THAT is the second reason for the square head - to stop that movement. The same concept for all valve adjustments.

I’m pretty sure this is the same issue I’m having… I’ll find out this afternoon

wow that is crazy!
Thanks for the tip Jeff, I think that's my problem. My buddy's mower has been pulling hard for awhile , now poping through the carb.
Heating up the valve cover helps in removal
I agree on heating up cover and look very closely for a cracked rocker arm
Mine is impossible to pull ; now I know why . Thanks for a great video.
WOWZ I just got one of these from my friend for free. Having the same problem. About to get working on it. Thanks man!
Nice fix Jeff: I found that if I changed my customers over to synthetic oil that it helps to stop valve seizing on those engines that run hard like on pressure washers. Thanks for the video.
Good tip!
Can you please tell me what kind of synthetic oil should use with Honda GVC190 and the weight??

Super repair Jeff. Any ideas as to why the exhaust valve got stuck?
not sure. possibly a low oil situation.
@@JeffsLittleEngineService Thanks - and keep up te good work. Really enjoying you videos

Hey Nice Input. What can it be on a GCV530 a cold start is on point but if the Engine was hard on work and I Stopp it and will do a warm start the Engine turns but no Start in 90% of cases.

warm start problems often indicate that the carburetor is flooding and needs to be rebuilt
@@JeffsLittleEngineService thanks for answer. On weekend i checked the valve and they are in good condition. The cam wheel and decompression works fine. So the last two things are the carb and in worstcase the piston rings
Better for valves being a little loose versus too tight, they might rattle some but will not burn a valve if too tight...
Thank you for the good video. Now the question comes up - Why did it crack? Perhaps the gap was incorrect at some point and put too much stress on it?
..... Engine operated vertically and/or low on oil ?
valve stem dries & ceases, rocker tries to compress valve & cracks ?
The valve was stuck when I opened it up
Rob Robbie only the cat knows an he ain’t telling. Sometimes stuff happens, Honda parts are plenty available and inexpensive.
On my gcv 190 the valve guide/seal slide up out of place which caused the valve to lock up.
In turn cracked the rocker arm.
The valve was not actually stuck or siezed.It could not go down since the guide came up and out of place.
Love the education you share! Greatly appreciated
Nice repair sir! I never have seen that on a honda engine. Nice catch! Roger
The arm band helps . thanks for posting this fine video. I will never trust honda the same.

The cam lobe on the one I'm fixing now doesn't match dead center when the piston is at max height. Is this a problem? I know the markings on the underside of the cam match the lobe at center with the cam housing. Mine is off to the left at max height.
Hi Jeff. I bought brand new rockers, I replaced them both, adjust the valves, first rope was fine. After that same story, it's ripping of my hand. Any ideas? Thanks
I would recheck valves or possibly a sheared flywheel key
@@JeffsLittleEngineService OR the exhaust valve guide partially pulled out.
Nice and clean job, tnk'u with the video helps me a lot, saludos desde Michoacán México mil gracias
Gracias amigo
Thank you sir, great workshop
STAY SAFE
Thanks, you too!
#1, Make sure there’s no pressure in the hose or at the pump. Without pressure she pulls right over.
I remove every water pump that comes in shop first thing
I’m not buying them a new washer pump period
My exhaust valve was stuck too. I pushed the valve into the cylinder and ball honed the guide. After assembly, it about broke my hand trying to start. After watching this I see the broken rocker arm! What causes the valve to seize in the guide?
since I have seen a few like this it must have been in error made at the Honda factory
I have a 3300 ryobi pressure washer with a GCV190 and so far it's been my worst investment ever. It won't even start now. It did after I cleaned up the carb etc. It was fine yesterday as for starting it up. Only pressure for half a second and then nothing. Left it outside and it rained today, started for about 10 seconds and died. After it started pulled the trigger and 3 small rocks shot out of the gun lol. It's barely 2 years old. Then it got extremely hard to pull, shut off the water and tried and pulled easily. Turned water back on still pulls, just doesn't start. I guess next step is to check the spark plug. I know what you mean about those valve clearances. I did a complete valve adjustment on my 2000 Honda prelude and it sounded better than before. Took me 2 days to do that. I am at a loss with this pressure washer so far.
I have seen the pumps fail and make the engine hard to pull the rope/hard to start. The rocks may have gotten into the pump too.Try using starting fluid to see what happens
This Ryobi pressure washer has oil burning white smoke coming from the pull start after it starts up I stuck a camera down the cylinder and it looks like the cylinder bore has deep gouges from the rings I would thing but I'm definitely getting annoyed by it
Heck ya I thought my pump seized up but turns out same thing is wrong with my engine. I noticed it starting puffing black smoke and shut off.
Very helpful information. Thanks!
Hi you mention in the video you tapped on the valve with a hammer to loosen the stuck value, I’ve had problems on 2 of these engines a had the rockers crack due to valve guide slipping, I think that is what happened to yours. I tapped mine back into place it lasted a little while then slipped again. I’d be surprised if this machine lasted very long before the problem came back as it will slip again. I just swapped the engine in the end. I’ve only had it happen on the 190, the 135 and 160 I’ve never seen it happen on those. Good video.
Pressure washers have a back and forth torque load while in use causing a shock load known as water hammer. This transfers to the crankshaft and ultimately the valve train causing valve springs to be tested to their maximums. The timing belt is rubber and stretches to absorb the shocks. Remember what happened when your feet slipped of the pedals on your bike when you were a kid? Same principle.
Could be that the exhaust valve guide is migrating out of the case, and contacting the rocker arm. I made a video in which I address this issue.

Jeff how do you find specs for value adjusting, compassion on different brands or what?
if I don't have a manual I look it up on google
Gragg Cain google
Gragg Cain if you need an IPL, go to ereplacementparts.com. , there you can see a diagram and find part numbers, and order parts if you want. Great company to do business with, though I think shipping is kinda high. Or shop on the webernet
Very interesting, I have a Troy bilt tiller with a similar Honda that MIGHT have this issue?!?
Thank you
I had the samething happen just now.. except the retainer screw is lost in the abyss
Owners need to keep extra exhaust rocker and timing gear
They will need them
So how do you get it unstuck without braking anything? Just lube it first??
yes and work it free gently if possible
what is that measuring ruler called on 8:24 ?
A feeler gauge
Jeff, is that a common problem on the 160 and 190? Great repair.
teh60 I’ve never seen it before. Not too common is my take on it
Not real common but I have seen it a few times
It’s getting to be very common now and I started stocking the rockers now
Scot h bright pads work great removing gasket and sealant debris
I saw the spark plug over there. Tried to tell you.
I searched for about 10 minutes..
@@JeffsLittleEngineService New Sub In The Net Work U R TY
Thanks. saved a visit to repair shop.
Why did it get stuck in the first place? I loosened my valve by tapping on it but it still sticks a little but I can push it down. How can I determine the reason for this?
good question. lack of oil or a manufacturers defect
Very good video...Appreciated.
My 190 gcv engine in my pressure washer would not start after shutting it down to move some items in my deck. Checked the fuel system, found no problems so I removed the plug and checked for spark. Had spark. Checked for compression, none. Removed valve cover and noticed about 1/8" gap between rocker arm and valve on the compression side. Noticed the exhaust valve was stuck in and I took a screwdriver and popped it out. There were no cracks in the rocker arm. Don't know if the piston has clearance for the valves or what could have gone wrong or if this thing is worth fixing. Paid extra for the honda engine on the husky washer. Engine only has 40 hrs on it. My mistake.
I have seen that before. you can ping around the guide to help keep it in place if needed
Peen, humm , thanks for the tip Jeff, again..
Holy over torque bolts much?
Awesome sounding machine
great explanation,perfect video.thanks
Great and interesting video. Well done w very nice detail. Thanks a bunch
thanks for watching
Very helpful video. BTW I thought I found you spark plug LOL!
Could you weld it and her her donebob?
maybe
Thank you for the video.
Thanks for watching Buck
Great video!!
great video. Barely heard the chickens.
LOL Got That Species Too Lot Of Work & Worth Teaching Thank " You" , & Jeff
Thanks for sharing
Thanks for watching!
That is exactly what happened to mine
You need to seal the valve cover with Honda bond
Thanks John.
I have the same issue the engine is locked I opened that cover everything is good I don’t know what else to check thank you
Carburetor could have flooded and filled the cylinder full of fuel.
If this is the case,the rings won't hold all of the fuel in the cylinder,your oil level is going to be high and your dipstick will smell of fuel.
The carburetor float valve and or float valve spring are your typical culprits.
Mines been wonderful except I’ve not been able to figure out why my soap ain’t coming out ‘? I’m sure it’s on my end. maybe anyone know. I’m watching your video now just started 🤞!!
what is the spark pug socket size?
Mime is 13/16"
Jeff my pressure washer runs but if you let off of the gun handle and stop spraying water it immediately turns off but of you keep spraying after a few seconds it starts smoking and smells like rubber is burning idk what’s going on
sounds like the water pump may be bad Trey
Most likely culprit is the unloader valve. This valve circulates water when you release the handle, thereby relieving the load on the engine. Almost every pump uses some form of an unloader valve. This is also a temperature relief valve that exhausts water to the outside world if the water gets hot enough from recirculation.
Thank you sir❤
