DW thanks for the tip on checking the exhaust valve on the Tecumseh engine. B&S uses the intake valve. So I was having classic symptoms of a failed mechanical compression release. I could not see the little bump on the exhaust side of a 13.5 HP engine. But when I carefully felt the push rod I could feel it move ever so slightly. So I checked my valve clearances Both intake and exhaust were loose. I found an 80 page online real Tecumseh manual (that I down loaded) which said both valves were set at it at .004. After resetting the values I could see it the exhaust valve bump. I put the plug back in and it fired right up. I had never seen your channel until this week when I was trying to figure out why my starter was hanging up on the compression stroke. I had no knowledge of a mechanical compression release. It lead me down the right path. I was right on the cusp of pulling the motor when I felt that exhaust pushrod move leading me to check clearances and beating the odds of a broken MCR on the camshaft.
Doing this same job to a 17 horse. Thanks for the tips on the pressure relief part that I have to order. Great job by the way.
excellent video, seems this is a much more common occurrence than we believe it to be in my opinion. I Am retired now and feel the need to find and repair these kind of issues. I am not sure but i think i must have been some kind of a maintenance person or possibly a mechanic in a previous life . I Will be taking on this job alone next weekend, a 13.5 H. P. Tecumseh, it is the only possible solution, i will also do a valve job reseating the valves, i am sure after twenty years it needs it, but it is not the problem. When you think about what is going on in side an engine it is not far from an engineering marvel . These small engine companies designed these things to be tuff , i am positive that changing the oil every 50 - 60 hours of run time is the key to longevity
Nice video man. Direct, to the point, and very informative for each step, along with the tool(s) and resources used to complete the task for the repair.
Nice work
The first sounds of and engine back together and running are always the best.
Yup, now I need to clean it up and straighten out the carb.
This was the first video I have seen on a compression release valve replaced and it was interesting to watch but, I am no skilled lawnmower mechanic and I would never try to do such a job but it seems you did an excellent job.
Great video. I knew that they had a compression relief in them but i didnt know how they worked. Thanks for the education.
Your right, that was no easy fix. You did make it look easy though. Thanks to you I did learn a lot today. I appreciate your time. Thank you!!
Thanks again for putting this one up, Bob. It was interesting and, as you said, one of only a handful of videos showing how it's done on a vertical shaft engine.
Well actually, I realized it after reading your comment from the Part 1 video.
I finally got mine on the camshaft. Just have to put the sump cover on tommorow and new gasket. Pulleys and put back on the mower. Hopefully I'll have mine back running tommorow. This unit was the 14hp tecumseh
I found these two videos very interesting. It's a whole world I did not know about! Thank you.
Thanks for the video, you did a good job. Funny you bought a mower off a guy who does not know the difference between SAE and Metric threads. Keep up the good work!
Another super job, DW. Keep us posted on the carb. I've only seen the plastic one once.
Taryl, has a great video on the plastic carb just watch that one. I only worked on the plastic carb one other time.
That's where I saw it! Keep us posted.
doublewide6, I, too, have run across the problem of a part being shown in a diagram but no part number being listed. Whenever this happens to me I find the Customer Service number and I call and speak with someone there. I have found that even though the person with whom I speak is not a mechanic and perhaps cannot immediately answer my question about the part number, he or she is normally pretty good about researching the information and getting me the answer I seek. Sometimes it takes a bit of time; however, if you really want the part, hey...what's a little time? I have even had the representative find the information later and send me an email when the information has been found. I just thought I would mention it as I truly appreciate your videos and the care with which you present your information. You have helped me more than I could ever tell you and I thank you for that. I hope you, your son, and the rest of your family are doing well. You all are in my prayers. I also put the Customer Service phone numbers in my contacts list to save having to find it again later.
Thanks I do not want to invest in the time to call and wait. I got lucky the seal is holding up well. I just ordered a spring the other day and got the wrong part, it never ends.
Nice to see you get the Tecumseh back in running condition 👍👍👍👍👍👍😀😀😀😀😀😀
Thanks for posting When we had this we use to loosen the plug but tighting a fire plug is no fun
Great job. I have not done one of these. I will remember this for the future Bob
I have not dealt with the Tecumseh engine all that much on lawn tractors, but I have to say it is a well made engine especially compared to Brigg's Intek side by side. I also like the fact that you don't have to replace the entire cam like you do when Brigg's compression release fails.
Great video. I'm about to do the same with a Kawasaki 17 hp. I think the biggest problem I will have is the weight of the engine. Won't be easy to get it in and out of the tractor and I'm not as young as I used to be.
Ok. Great video part 1 and 2 together.
I have a 2004 B&S 8 HP vertical shaft with both electric and pull start. It pull starts usually on the first or second yank. Have to admit, the oil has not been regularly changed. Very irregularly. Anyway, for about the last year when the engine shuts down it's a rough stop instead if smoothly coasting to a stop. No metal banging. Just sounds like there is still compression in the cylinder. Am I looking at the same issue you just addressed in this video? Or could it be just a valve adjustment? That has never been done. When it's running, it runs real well.
Great pair of videos!
Great video dude! i just happen to have a riding mower that i couldn't figure out and it will soon be running now! again thanks for all your video's!
My 18hp briggs is doing the same thing, is it the same as that one on parts?
great job and video
Thanks for watching, happy to have you aboard. I just watched your loading and old start cold start of Mr. Moss. I'm thinking about putting a winch in the back of the truck, but not sure on how to attach it. Then I saw you hand winch and that looks promising and easy for loading tractors in the back of a pickup. I will search to see if you have a video on your winch install.
That ole Tecumseh sounds really good Bob!
I got to get to the carb, it was not sounding as good today. Thanks for watching. Bob
Great video .My new 21hp b & S motor has maybe 2hrs.on it and now have same starting prob.Gonna ck valves tomorrow.without plug spins like a som B,with plug gets stuck . Motor prob put together on a monday.
7:41 You couldn't find the crankshaft oil seal? Did you try calling a bearing supply house? They stock those!
Very interesting video, thank you, keep up the good work.
Thank you
Nice work!! Obviously you have some substantial experience! This is a bit beyond my scope and range unless my life depended on it!! (LOL) Since I'm 70 years old it's hard to crawl under a motor and bent my neck so i can see where the mounting bolts go so I probably won't tackle a job like this myself. I have a Troy Bilt Super Bronco and I'm getting power to the starter but it acts like the compression is preventing it from turning over fast enough most of the time to start it but i usually can coax it into eventually starting. I'll will check the battery connection and starter solenoid tomorrow but not sure if this has a stupid compression release or not as it's just one more thing to break or fail. It might just need a valve adjustment too? Impressive Video!!!!! Where are you located? PS. the motor runs great when it starts.
A work around is to remove the air cleaner and place your hand or something like a piece of rubber inner tube over the intake of the carb while cranking.
That creates some vacuum on the intake side which results in lower compression.
After is starts, higher compression is not a problem.
It's a bit of an art but if you have trouble getting this procedure to work, spray a little starting fluid into the carb then palm the intake as completely as you can. As soon as the engine start rotataing faster, remove your hand.
Great videos. The problem I have is the engine is turning but it’s not starting. I cleaned the Carburetor, and still no luck. Can you give me an idea of what might be the problem?
i have the same problem how long did it take in hours did it take to do complete job. it will probably take me double that time.
Very detailed & informative video.
I have a 1992 kohler command CV14hp that will not start. I have confirmed that i do have fire to the plug. I am getting fuel to the plug. My compression measured 120psi with a standard compression tester. I have sprayed a little carb cleaner in the intake just to rule out fuel supply & it would not start. Do you have any other suggestions that i could check?
Nice job. I found the 2 part series interesting.
That's good. Thanks for letting me know.
I know what you mean by having people"lie"to you about something when you buy it.You have so much work in it and unless selling to make a lot on it.You pretty much have to keep it or trade it for something really good.Love Tecumseh motors"hate"that Tecumseh parts are way more than Briggs.Ex.Briggs push mower air filters between 3 and 5 dollars.Tecumseh push mower air filters 10 to 15 depening on where you get them.
Great Save Bob!! Hugs to the Little Man! Zip~
My kohler command pro 23 is extremely hard to rotate by hand even with both spark plugs removed. Won't start and very hard to crank. Shows no compression in one cylinder and 100 lbs on the other. Won't start. I'm lost. Any suggestions please. And how do I contribute to you patreon
Good job. I like it
Awesome video getting ready to do this on my engine....
Theses are better than any of b/s junk and fixable also
OK, so this has compression release built in; good to know. How does that affect the compression readings I'd get on a gauge? Cranking compression is going to appear "low," right? IOW, the engine could have 120 psi at running speed, but 90 when it cranks?
Great video, very educational. Thank you!
No Problem I'm happy you liked it.
sorry about first question . i got the time it took later in the video
how do i donate one time or occassionally
Did this and changed head still having this issue.what do you think
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?
Thank you
Do you happen to have the part number for the Mechanical Compression Release as I'm having trouble just finding that particular part. I have been able to locate a full camshaft with the MCR installed but can't seem to find the MCR by itself.
I have just completed your 2 part set. I have a question for you. I really don't too much about a Murray tractor I own that I have had problems with. Q: when you start the engine, Does it matter where you set the the throttle, I have a turtle on one end and rabbit at the other end. Is there a position needed to engage the compression release? This tractor came with the house I live in and did not come with a book
thank you for reading
The compression release is automatically engage at low rpm *like when starting*
As soon as the engine fires up the compression release swings out of the way and is not used at al while the engine is running. (centrifugal force overcomes the spring tension that hold the compression release in place - i.e., so it sits on the exhaust cam lobe so it will hit the valve lifter)
Doublewide6 what are those other shafts with gears you had to line up besides the crank shaft and the cam shaft? What function do they have?
Now do you know they size of feeler gauge to use?
Job well done buddy !
Thanks!
" I was going on this other guys word" ... Been there.
They always were running last year. Bet.
I have the same engine but mine was leaking right at the center of the block but I can't determine where it's leaking. what do you think is causing it to leak where it leaks?
Thanks for a very informative video.I will subscribe.
Where to buy compression release kits
11 tho clearance seams way lose with only 4 tho on intake is that why it rattled on start up ?
Nice job!
You have great talent, don’t waste it on junk! What a piece of crap! Now I know why the industry is going cordless. Times are changing for the better. What an eye opener!
Old gas, old oil, frayed electrical connections, failed internal Engine components.
Horse & buggy, model T. Say bye to this old technology!
Good video man
So where did you buy the pin and spring from?
Hey there. Hope your family enjoys a great Mother's Day. Is there anyway to do patreon as a one time and not just a monthly?
We had a really nice Mother's Day thanks for asking. I don't know Patreon, but I think the idea is to be monthly. Thanks for looking into it. Bob
Good video thanks
where did you get the relief kit from?
You actually did get lucky with the engine. An engine produces power a motor convert it, just saying fella. Well you are real lucky the gears did not get damaged from the metal and parts inside the pan or the crankcase bearings journals cracked from being spread from metallic compression of metal between the gears. Industrial supply should be able to get you any seal you need by size you tell them. You should of know when a so called mechanics sell a tractor he know there is a serous problems with the item. Interesting video to say the least. One more point to remember, the older engines where so well made that the new ones just cannot compare. Simplicity was there claim to fame. The new engines are just always in need of something. When the youngbloods get there hands on them watch out. You get the roll of the diec with outcome. Most of the time negative for sure. Good day and peace. VF
nice job.
that looks easy now that I've seen it done.
Easy but time consuming. Just don't forget to line anything up correctly when putting it all back together or it is not going to be an easy job.
How did you get the parts so clean?
Sounds like sarcasm? But if you are serious, I used a scraper on the gaskets and carb cleaner. I used kerosene and a paint brush to clean out the inside the best I could.
For sale????
Not yet need to straighten out some other stuff.
Whats the engine in the video intro? CAT Engine?
