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.
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 !! 😉👍🏻
Excellent tutorial as always Hester! You make it look so easy! 😃👍
Thank you Scout! 👍🏻
Very easy to see and understand. Good explanation. Thanks for the helpful video!
Thank you! 👍🏻

Very good point! So many lovely issues with these heads 😂
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
Nice job Hester, thanks for the video.👊
Thanks John! 👍🏻
Anytime bud
Great video. It helped me.
Glad it helped!
Thanks for showing this video.
No problem 👍🏻

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?

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 👍🏻
thanks for the info, I have a spare rubber vacuum hose for the fuel pump too
Definitely good to have on hand 👍🏻
Something to note is that all valve lash adjustments should be performed with engine cold.
That is correct 👍🏻
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"
This is where those go through sockets are the tool to have.
I love those! Pretty sure I have a set somewhere lol
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 👍🏻

@@hester781 thanks alot
@@ChrisLoganToronto anytime! 👍🏻
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

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.
Do these engines have compression release?
Yes they do
Just replace the hose and your money ahead 😊
Agreed! That’s what I alway do👍🏻
That's not right my friend ..... adjustments are .005 -.006 - you did them too tight , you just went .06 !! 🤔
