I always check the pivot studs too, they can loosen up and really cause problems with the valve adjustment, or ejecting the pushrod and giving you a dead cylinder.
I have repaired three Briggs single cyl that the pivot stud on the intake had come loose and off course the engine wouldn’t run past idle. Upon removing both studs the exhaust had a sealant, locktight, and the intake had none. Cleaned and used locktight on the reassembly of the studs and have not had any issues as of two years ago.
@@hester781 I’m thinking that the assembly trays of the two different valves may of had an application inconstancy as the trays come with sealant already on them. Or maybe the engineering thought the intake didn’t need any as the valve doesn’t experience the extreme expansion and contraction that the exhaust does.
You can certainly follow the manual. However the rule I follow and have followed for years is the valve being adjusted must be fully shut with no overlap happening. Which is why myself and most other technicians will simply rotate the motor until one valve is fully open which means the other valve by default cannot be open. Then repeat for the other valve 👍🏻
The decompression valve does not come in to play when you’re doing a valve adjustment in this fashion. The whole theory behind it is if one valve is open the other valve isn’t being affected at all by the camshaft👍🏻
Good afternoon! Friend, I have an engine like this here in the Amazon and I have a question: Is it possible to use this engine horizontally, with the heads facing up? And how would the lubrication be? Hugs and thanks
I'm a newb, but I need to check this issue on my own engine. I was wondering how you were turning the engine over? I've seen others take the fan cover off. Thanks!
I can't remember on this one if the cover has to come off or not but you are correct I was turning the flywheel by hand. However with both spark plugs out it would be just as easy to reach underneath and turn the crankshaft as well 👍🏻
@@hester781 Thanks, will see if I can do this on my own set-up without having to remove all my covers and air intake. My engine is in the tub of Max 2 6 wheeler
Hey Hester great video - what was that little black hose called at the end of the video (that gets cracks and affects fuel pressure)? I've been fiddling with that thing for 3 years to get my lawn tractor to run properly (Intek xrd 724cc 23 hp) I don't know how to order one.
So there are a few different styles of these fuel pump vacuum hoses. Here’s a link to an example of one, luckily amazon has all of them. Hope this helps 👍🏻 Welironly OEM Briggs Fuel Pump Vacuum Hose Part# 793147 ;from#killian3790; TRYK8291759296696 a.co/d/4khVcA1
You got something against English Hester? Ah ha, nice video bud keep up the good work, my engine seems to be English or 3/8", 7/16, 1/2", 0.005" gap. It's a Briggs! Cheers. U.S.A.
You are correct! I realized this after editing and someone else pointed it out in the comments. Although I’m actually pretty surprised you’re only the second person to catch my mistake! Good eyes 👍🏻
@@hester781 It's all good , I run a small ATV-Mower Repair Shop and I've goofed up way worse and many more times than I care to admit !! Thank you for what you do , and sharing your knowledge with others , not many can do, or want to do what we repair for others or to be self sufficient !! It's a dying profession !! 😉👍🏻

Very good point! So many lovely issues with these heads 😂
Excellent tutorial as always Hester! You make it look so easy! 😃👍
Thank you Scout! 👍🏻

Interesting, I’ve had and fixed that same problem but never removed the exhaust stud if they were tight. I wonder why they wouldn’t just do both?

I'm getting ready to do this, but I have to replace the heads first as I finally bent my push rods on my 24 horsepower intek.
Ugh, sorry to hear that
Well done video, however I did notice that it looks like you are using a .06mm feeler gauge which is about .002". Might want to recheck those valves.
you are correct! I don’t know how I missed that… thank you for letting me know 👍🏻
So, is this the correct size in the video? Also do u have a part number for that hose? Thanks, great video.
@@andymartinez5528 I believe the specs are around .014” or .355mm. Don’t know about the hose.
Peter griffin ??
Sound like most are going at 0.005"
What happened to the 1/4 past top dead center?
Not sure what you're asking
@@hester781 The manual says set cylinder 1/4" past TDC, compression stroke. Check valve clearance .005".

@@hester781 I understand, but Briggs & Stratton for this particular series have that at 1/4" from TDP because of its design.
@@jamesm568don't overthink it. All you are setting is the clearance when the valve is closed, simple as that.
Wish I’d known of your videos before I worked on my last riding mower - RIP!!! Nice job 👍
Thank you! 👍🏻 also I’m sorry for your loss
Very easy to see and understand. Good explanation. Thanks for the helpful video!
Thank you! 👍🏻
PROPER WAY TO ADJUST VALVES ON COMPRESSION STROKE ONLY TWO VALVES CLOSED ADJUST NOT THE OTHER WAY LAZYMAN STYLE IS WRONG
WHY ARE YOU YELLING!? 😂😂😂😂
Shouldn't you take the decompression valve in consideration when doing a valve adjustment?
The decompression valve does not come in to play when you’re doing a valve adjustment in this fashion. The whole theory behind it is if one valve is open the other valve isn’t being affected at all by the camshaft👍🏻

To my knowledge, unfortunately no you cannot

Is the bolt that holds blade normal thread to undo anti clock.?
98% of the time yes

@@hester781 thanks alot
@@ChrisLoganToronto anytime! 👍🏻
Good job!
Thank you! 👍🏻
Torx can be a variety of sizes depending on the model type and code. Nuts too.
Yes sir. I just say what size I’m using because ask me too and worst case if it isn’t the size you need, it gets you in the right ballpark 👍🏻
What is the name of that rubber tube to replace that you showed at the end of the video
I believe Briggs calls it a fuel pump vacuum hose 👍🏻
It's called a vacuum hose.
Something to note is that all valve lash adjustments should be performed with engine cold.
That is correct 👍🏻
The word thousandth refers to thousandths of an inch. you are using a .06mm feeler gauge which is metric, so it is .06 of a millimetre
You are correct and I’m well aware lol, I realized when editing. It’s funny that only 2 other people have noticed besides you
Can incorrect valve adjustment cause surging? Thanks
@@rayalliston7702its plausible but more often surging is the result of a lean condition such as a dirty/restricted carb or an intake leak
You got something against English Hester? Ah ha, nice video bud keep up the good work, my engine seems to be English or 3/8", 7/16, 1/2", 0.005" gap. It's a Briggs! Cheers.

Do these engines have compression release?
Yes they do
I remove studs and clean holes really good, then add red lock tight
There bad about coming out
Excellent idea, I’ve had to do that to a few in the past 👍🏻
thanks for the info, I have a spare rubber vacuum hose for the fuel pump too
Definitely good to have on hand 👍🏻
That's not right my friend ..... adjustments are .005 -.006 - you did them too tight , you just went .06 !! 🤔

This is where those go through sockets are the tool to have.
I love those! Pretty sure I have a set somewhere lol
Just replace the hose and your money ahead 😊
Agreed! That’s what I alway do👍🏻
Great video. It helped me.
Glad it helped!
Thanks for showing this video.
No problem 👍🏻
