Never seen the Link for the Compression Release Kit ..... Only Link is for the Cam that has the Compression Release already on the Cam..... is there a Kit that is for the Compression Release Components Only ? .... that way i can just Replace what is actually Broken .... my Cam is Good..... Thanks for the Great Video.
@@bobbysutton9024 I apologize I worded it wrong. I should have said cam relief kit.
Of you removed the plugs and it sound does that mean everything is working properly or did I just released the compression only?
Man, thank you, I adjusted the valves several times thinking that was the issue. Now I know what it is. Thanks again
thanks for the information, i was thinking my troy built tiller engine had a problem with the valves or the cam shaft. now you identified the entire problem exactly. thanks again
Well explained. I've never seen that much sludge in an engine ...nicely cleaned up.
Great diagnosis Bob, looking forward to video #2!
Thanks Me too!
This will be a helpful video to anyone dealing with this issue, nice job
Yes, I think so, it is getting a ton a views as well could just be the time of year for the video.
More videos I watch better info! Your video was very helpful! Showing the intake/exhaust valves & mentioning how u can see if compression release was wrkg helped me a lot!!!!
Waiting for part two, chop chop! Good video. I think you said Techumseh, but the links are got Briggs parts and none for compression release. Keep em coming!
I'm waiting on parts and excited to get part 2 out. I'm really busy at work and in the shop, so hopefully I can find time to film it. I still have that tractor hanging on the hoist taking up room in the middle of my shop.
Oh good. You checked the valves. That was the issue with my free Craftsman last year. Thanks for the further data.
You bet. Thanks for watching and taking the time to comment.
Damn man, nice find! Like a pro!
I don't know if it is worth the effort that tractor will sell for at most $300. I have 2 hours in it already plus going to pick it up.
Nice work DW6!
Thanks Tony!
Great videos on the Compression relief. Didn't know they where there. Do you know where I can purchase the kit without the entire camshaft for a Kohler CV13S? Thank you
Thank you! Now I think I know the problem I have with my tractor.
Appreciate you posting doublewide6! Just a little tid bit of info for the people interested in tackling this job. It's a good idea to remove the spark plug and push rods before cracking open the cranks case / sump. It will release the compression load on the crank if you need to rotate it and spring load on the cam for easy removal.
just loosen spark plug will kill compression
Set Intake valve clearance to .004 tight. If this doesnt help, your compression release mechanism on the camshaft has went south.
This is the trick. I've seen .006 not be enough but .004 did the trick even when compression release didnt work
Hope you get it back together and running like a champ. I know you will!! Do all over head valve engines have the compression release? I adjusted the valves on our zero turn a while ago and it doesn't have compression release as far as I know.
I don't know. I don't think so. The bigger the engine the more likely it will have it perhaps.
I'm glad to see you tackle a vertical shaft single cylinder engine. I don't know why, but most of the people I like to follow don't tear into these too often.
It is a lot of work getting the engine off the tractor and you never know what your going to find inside. Who else do you watch on youtube?
I watch everything 805Roadking puts out there and Zippo Varga too. I used to follow a few others as well but dropped them for various reasons.
Okay thanks I watch Zippo I will look into 805.
The 805RoadKing group is fantastic! They do some truly amazing things with engines. Another good one is TaryFixesAll. He does silly little skits with all his repair jobs and he is goofy as all get out, but he knows his stuff.
Thank you!
Great show brother 👏
Getting ready to put in a performance cam and tabit in a motor. Can I use just reg. grease for assembly lube,, or is royal purple 90 weight on the parts good? I do not have any specific assembly lube thus the question
What were those two gears you took out from the left and right. I know the crank, and the cam.
nice job.
It would be nice if you could explain what and how the gears work. Also how you can tell when the timing lines up. I like your videos and am learning more and more on small engines
the woooruff key in the crank shaft and fly wheel set the location of the mag built into flywheel as the magnet passes the coil it generates a spark while piston is located a tdc on compression stroke
I’m having the same problem with my mower but mine has a flat head, to would it have the same decompression vale probably?
Wow, it has a set of balance shafts in it? Looking forward to the next video. That oil is yuk!
As you can probably tell I am not really at all familiar with these Tecumseh engines. It is an interesting system of how the timing works with all the balance shafts.
I just find it interesting a company would spend the extra dollar to put a balance shaft system in a inexpensive engine, especially a one cylinder. I could see one in a four cylinder because of their inherent rotating mass issues.
Mine does that even with a jump from a 6l v8 in my Denali. But it's an 80s craftsman n havnt had oil change in decades
great diagnosis Jim. What a pain (literally) Bruce
I'm happy you liked it, and my good friends call me Bob :}
I knew it was Bob. My comment before was for not2fast4u2c. HIS name is Jim and I got them transposed. My bad but no going back now BOB. haha
That's okay I'm just teasing you. Bob
We all seem to be dealing with "wannabe" mechanics right now my Friend. I'm dealing with the aftermath of a "repair" shop that totally screwed up a 2008 Simplicity Conquest and it's Vanguard engine. It always amazes me what people THINK they know vs. what a proper repair is. Great save so far Brother! Hugs to the wee one! Zip~
If you can't fix it right, you got to know when to throw the towel in. Zip, you are much more of a talker than me, so I think this topic will make for an excellent video on your channel (it is also going to draw a lot of comments). Like it or hate it, you are getting a special request from Doublewide6. Take care Brother.
im having an issue with my Tecumseh motor on my tractor. The previous owner said it blew a gaskit and there is a whole lot of oil at the front end. What would cause that to happen and where can I find that part?
I had the same issue of starting. It ended up being a loose ground to the chassis. Easy fix after adjusting valves.
I'm just wondering where you are from love hearing you talk
NJ
Thanks reckon I have the same problem with my 15.5 briggs
had a similar problem with a lawn mower I went to buy from a neighbor, and it was overfilled with oil... oil poured out of the chamber when I removed the spark plug, and it poured out of the muffler / exhaust pipe too... Once I drained the oil and cleaned it, it ran fine... It had fluid lock / vapor lock.
Sometimes when you see that the problem is a leaky seat. If there is gas in the oil the problem will come back. I have a video on how to fix it on a Briggs 17 intek.
valve adjustment on that Tecumseh you need to adjust your valves and set if you don't you may run into bigger problems that's been to push rod or even break the retainer nut and it's a common problem with that 17 horse Tecumseh
Nice video Bob . Hope you can save the engine . A lot of metal flying around is not good.
Cheers Pete.
Well, you are right about the metal. 95 percent of the metal was on the bottom of the engine sump (I have the engine turned up side down). Anyhow, The battery is new that I was cranking with, so I'm thinking once that compression release broke the engine never started again. Also that jump starter that I used can jump my V8 truck with no battery even installed.
That's good Bob . Might well have saved it.
im 87yrs old worked on eng all my life as a hobby from modle air plane engs to outbord eng lawn mowers my army truck flathead six i dont recall ever having to tinker with valve adj, i did grind the on my army truck to help comp. fixen to rebuild carb on my army -truck need to stay busy -- give out but dont giveup..lol
todays small engines have a compression release built into the camshaft, proper valve clearance is critical for these to work
hello i have same problem with my tractor y check everything and i found the terminals on the battery have corrosion remove it clean real good with metal brush and run like a champ that was my problem good luck for all
Take the plug out and see if it cranks o.k. If it does, it can be carbon on the piston, the crank key can be sheared because the blade is bent, dragging starter, etc. If the rockers are loose, the valve seat can be loose. Pull the head and check. Replace the head. Check the leakdown to check rings, valves, and head gasket.
What is the part number for that gasket that goes between the top and bottom part of the mower?
Haven’t watched yet but my guess is a loose (stuck closed) exhaust valve! Had one with a rocker arm so loose it wasn’t on the push rod anymore
I can't tell you how many batteries I went through with these mowers, I wish I had seen this video years ago!
Always check the valves first.
Jeffrey Dubinsky flooding carburetor will give the same type symptoms,but the gasoline being thinner than oil,it will blow by the piston rings and flow in to your crankcase.
Check for elevated oil level and do a sniff test to the dipstick.
Repair/replace the carburetor and change the oil.
im stuck. i adjusted valves, no luck, so opened up the case, compression release key is fine. What would the next step be?
I have a MTD Lawn General 1993. It has the Briggs 12.5 hp IC engine, glad I don't have to worry about a compression release. Good video.
Link to the next video would be highly appreciated.
A large problem with the Tecumseh motors in particular is the issue after you got to put those bolts back in the bottom to mount it back up use Teflon tape on the threads or the bolts will work themselves loose on ya and fall out... I've had how many of em here over the years after mister shade tree mechanic replaced either that compression release or a leaky sump gasket the mounting bolts work them selves loose. You can't really use locktite because of all the oils in those bolt holes it don't stick to anything.. If you folks want to totally avoid breaking a compression release and avoid making junk out of your tractor use Synthetic 30 weight heavy duty Motor Cycle oil in the crank case and drill a dime size hole on the bottom of the muffler on the same side as the header pipe is at. The mufflers were too tight to begin with and most usually spring a little rust hole anyhow. However there are places in the southern USA where they don't get the rust like we do in the northern USA so breaking a compression release around here is not that common because people change their oils here and we have a shorter cutting mowing season here so the machines are not used as hard and oil usually gets changed. But for those of you with no pin holes or rust on the muffler make that dime size hole you will gain a little power too.
So drilling the hole in the muffler then what let’s moisture out so it won’t rust inside the muffler?
Is this engine a Briggs and Stratton? Thanks, I'm having the same situation with a 20 year old Murray 👍🏻
Check and se if gas is in oil if so replace needle in carb it took me a while but I figured it out
My 1999 Yardman sounded just like that until I adjusted the valves
my bottom valve (intake) wont move, I know I adjusted them right per the specs on troy bilt pony with briggs 15.5 hp engine. both rods are not damaged, I have no idea what happened but days before it would start up and run then stall. I am thinking broken compression release in engine. On my engine the exhaust valve is on top and intake on bottom. Now it hard to turn over and never starts even with jump starter hooked up and batery and carb are new. New fuel filter and air filter. There was gas in engine oil before carb replacement but after carb replacement it ran then stalled after 20-30 seconds.
I can't stand buying these machines from hack repair guys anymore. I've bought huge lots of snowblowers, garden tractors, mowers, etc and they all have more wrong with them than before they started messing with it.
I try to stay away from other "mechanics". I have had it happen about 4 times in the last 3-4 years. I should know better.
I only made one mistake and it was to buy a rebuilt (That's what I thought) riding mower from a certified " backyard mechanic". Everything else I own, was free and I intend to keep it that way. I do my own repairs with the right NEW parts. When my neighbors wants me to fix their machines, I just show them the way to the small engine shop near here. I'm not going to back stab the guy livelihood. That's my motto.
Very true; If they cannot offer you a decent warranty,don't buy it!
I don't mind buying them until i see some people weld the rims to the axles and they weld pulley wheels to the shaft
Very Informative, Good Job!
the quick way to tell you probably have a bad solenoid is to short across the two big lugs on the solenoid if it spins then replace solenoid --- the way a solenoid works is when you turn the key switch on it conn batt. to the winding in the solenoid which closes the contacts inside to conn. 12 v batt, to the starter ..if this dont happen all you get is a click........
I am confounded. My Briggs and Stratton 14HP Vanguard (Model #261777, Type #0144-01) engine's starter turns over very slow or not at all when the starter is installed. I have checked valve adjustment. I turn off the gas when I turn it off so no gas can siphon into the crankcase.
When starter is removed, starter runs as should be expected. No binding or noises that I can detect. I disassembled the starter this past Saturday and cleaned up the brushes and armature. And lubed the end cap.
I'm very tempted to buy a new starter but have this feeling that I don't need a new starter...that I'm missing something.
Could a failure in the compression release mechanism/system be be the problem?
Do you have any advise/council?
Great video by the way.
Hope you got it figured out .... I always go thru those steps and most of the time if the mower is over 5 yrs old , it ends up being a ground wire !! Clean , put a bit of grease on bolt etc . Tighten it up and that usually solves the problem !! - Thanks

Its the compression release period it breaks the centrifical part you have to get a new camshaft youll find it in the bottom of the case the pin breaks and take the oil pump out when u put it together then put it in last
I have same problem with too much compression I just hope it is valve adjustment and not this job...we will soon find out
moat people want to in crease compression . more comp more power?????
the valves are either closed or open to make them work right no in between
Good video, but a showing of the kit and install would have made it great.
i know a good way to tell about comppression is to put a little oil in spark plug hole recheck comp if it goes up its the rings are worn if it dont go up its the valves they need grinding
don't need light bulb tips 2wide LOL
I’ve never had a Walmart battery that lasted over 1 season... I will not buy one. I buy a good one from the Auto parts store, it’s still good after 4 years..
i usually use napa lawn and garden, interstate or federal are my choices never had a problem napa is my favoite the price and they work good for my mowers
Yep learned my lesson
less landfill xD
JUST WATCHED THIS VIDEO AND I'VE GOT THE 17.5 BRIGGS AND STRATTON INTEK ENGINE THAT I JUST REBUILT IT'S DOING THE SAME THING THAT THE ONE IN THE VIDEO IS DOING. WHAT IS THE CORRECT VALVE SETTING ON THIS ENGINE 31C707 IS THE MODEL. THANKS FOR YOUR VIDEOS THE'RE GREAT
Same motor and problem im having
Most of the Briggs Intek and similar engines for riding mowers are:
Intake .003-.005
Exhaust .005-.007
take plugs out to reliev compression if its still stiff its been run with low or no oil and ruined the crank shaft or the rod looking at those gears its been cooked
My Mtd Yard Machines ran fine til a few weeks ago. Now it won't start. Replaced the battery twice. Find out, it will crank over fast with the spark plug removed but very slowly when the plug is in. What is the exhaust valve? I tinkered with my exhaust/muffler cause it is rusted and I bolted it so it doesn't leak anymore.
set both valves @ .003" so compression release will work, then it will turn over fine
What does it mean when fuel runs out of the exhaust pipe on a Kohler engine. Also had problem with compression getting stuck at top ,dead ,center. But was able to turn crank with wrench.
Your carburetor pin isn't working right to stop the flow of gas to the engine. I had that problem until i put a new carburetor on plus a gas shut off valve on the carburetor gas line
Without the gas shut off valve i use to park the mower at a good slant to keep it from flooding the engine with gas it worked that way for awhile
You might just need to adjust your carburetor pin or it may need a new carburetor bowl solenoid put on you'll need to change your oil and oil filter too i have cv16s Kohler pro and cv491s Kohler command engines
Hopefully I'll be getting another cv491s but I do away with the cheap gas pumps cause they can leak gas into the engine so I don't want that
@@Mike-su8si the backfire solenoid on bottom of carb is sticking, and letting fuel in after it is shut off
@@DWinnie67 it wasn't though because i put a new one on and still had the problem until after i put a shut off valve on and it fixed that problem
Then I seen on the solenoid rubber tip was to skinny to block the hole so it wasn't doing much good my original rubber tip was wider
@@DWinnie67 what was wrong with that was the wrong rubber tip and i couldn't find the right replacement rubber tip
I appreciate the thoughough trouble shooting.
fascinating
You got to know what your looking at.
sometimes if overfilled with oil, or flooded, will hydro-lock.
fleamine Yep. Too much pressure on the piston
Hi... maybe you can help me....I try everything but my starter gear won't pop up????
A very simple way to relieve compression is to take out the spark plug. If it then turns freely problem lies elswhere
Blackie Chong hi there I've got this problem with a quad bike any idea's
Exactly....spock would be good at these. Live long and prosper
Im gonna try that with my john deere 318, thanks a lot
Looks like to me ,you win all the way around .
I guess when I get stuck with a tractor that needs a major repair it makes for really good video footage because most don't take the time to fix them.
Lol I was like how can this happen and then I thought ah exhaust port?
Do know why this happens?
I wish somebody would answer this question: If you take the spark plug out, does that release all the pressure????? I ask that because MY MOWWER STILL TURNS SLOWLY WITH THE SPARK PLUG OUT. Anybody have a answer???????
Maybe you're magneto is resting against the flywheel
@@Mike-su8si It turned out that the "NEW" battery was was fried after continuous charges due to failed starting attempts. It turned out the starter was fried too after all the failed attempts to start it. In other words the engine refusing to start caused the battery and starter to die.
The thing that caused all these problems was unadjusted valves. The exhaust valve was so late in opening that the pressure in the cylinder was greater than the starter could overcome and that extra pressure wore out both battery and starter.
I got a new starter and battery, adjusted the valves and now it starts good.
@@Hooverdarnit oh my top valve was loose one time before on my cv16s Kohler pro I didn't have the right tools so i just tightened it a little bit and its still working good
if you want learn how fix your mower get a wiring diagram and learn how to read it if you can read a road map you can learn how trace wiring learn what every thing means for instance on relay contacts NO stans for normaly open so they would close as the relay is operated also if it says NC it means they go open as the relay operates the key switch --on makes this happen you learn how to use your ohm meter its is very simple to use you get a meter for less than 10$ it will test any thing for the average homer owner all you need on you meter is ohms ac-dc volts dont worry about reading amps you get volts ohms fixed current will take care of its self im a retired tech still use my meter almost daily wiring on my truck restoration
Take air cleaner off seal off all air to intake turn over when it spin open air to intake. Pain in butt but its running.
I have brigg ridermower 1987 need helping wiring
I just took out the spark plug, turned the engine over and blew all of the crap out, then replaced the spark plug, took off the air cleaner cover, covered the air intake with my hand, turned it over and once it starts spinning I take my hand off of the air intake, Vroooom!!
the problem i have had is low compression never have i seen too much how much is too much if it want turn over its not compresion just loosen spark plug see if rotate then it sound like t he wrong spark plug in stalled (too LONG ) ---- weak battery could give this problem also try putting compressiion gauge in spark plug hole measure compression 120 psi is good 85 -90 is low but still will run
Spark plug 😀
That's too difficult for me to even think about attempting..... good video tho
Well hopefully you never have to attempt it. It is not the most common thing.
Same issue with my crapsman 20 minute job and my 100$ mower is like new.
Heres a tip kids ....line up all timing marks before removing any parts....also ...DO CLAMP PLYES TO ANY SEALING SHAFT
4000ths both !!!!!!!!!
I get a chuckle from a lot of these TH-cam mechanic videos where their workshop is junky backyard with rusty machines everywhere out in the weather, then they rag on what they call "crappy" manufacturers or poor quality. I've got 3 lawn tractors, 45, 33, and 25 years old, all run perfectly. Ya just gotta take care of them, keep them out of the weather, and properly maintain them and they will last almost forever. Great video, thanks!
thats right, just keep them out of the weather,and fresh fuel in the tank
If the battery is only showing 12 volts it needs to be charged before load testing it.A fully charged battery should read around 12.4 or more
from all that sludge it looks like they were using Penzoil in it.
There was a ton of sludge.
I'll use any oil as long as it keeps it wet
My buddy would have this torn down and rebuilt looking brand new in one night no new parts nothing he would refurbish whatever you could and swap out from other ones
The fuses that’s
new cam needed
My same engine as that one needs a new flywheel
How much would a repair like that run at a small engine shop????
Probably half the price of a new driving mower my one neighbor use to get his worked on every year just to get a new plug air filter oil change and gas filter and he paid $325.00

Once the compression release quits working, DON'T run your motor anymore! Fix it! It has those little parts floating around inside the engine, basically banging against other moving parts and could ruin more parts or get lodged in places you don't want them. I've seen some horror stories caused by those little parts and you can actually ruin the entire motor if not fixed in time.
They just don't make any of those starters powerful enough. upgrade to a chevy 350 starter similar to older bolens or cub cadet.
Will mount on the same
You should of stuck a clean plastic bag inside air intake so no air gets through preventing compression - motor will run and start, as soon as it does pull the bag out.
why not just use the choke insead of a bag???????
High compression Get a high torque starter and get some diesel
No
there is fine (FUCKING HUGE) line between a tractor and a lawn mower
I would replace the engine for something better,plastic part in it not worth it,tbh:/
On ya for persistence & effort tho xD
Rember you don't make yourself look better by putting someone else down
You can jump start the battery with a battery charger just put it on about 6 amps.
i think some one is barking up the wrong tree about the too much comp. no such animal more comp more power///???????
.10 is way to much .04 is the right
Go ahead and burn the starter up..valves need adjusting...just left 3 mins in the video
GREG McCarter lol wrong answer smh need to know before you comment
Find a s.t.x.30 john Deere ?
