Awesome - very helpful and informative.

Bravo 👏 excellent presentation

❤❤❤❤❤❤

They're not flathead anymore.

This is great! Do you have one for ignition and spark?

This was an absolutely fantastic explanation and break down of how things work. Ty for making this video :)

Great video. I was keen to learn how the flywheel works.

That's the way to make an instructional video...Pertinent information given concisely without a lot of extra verbage which only leads to distraction...Nice job.

Awesome video, big thanks!

Diffantly has the video instructor voice.

Did he explain the Governor? Maybe I missed it. It's vital part.

I like when BLOGGS AND SCRAPPEN ENGINES ! GO STRAIGHT ! INTO THE MEATAL SHREADDER !! LOOKS ! SO ! BEAUTIFULL !

I'm trying to learn about small engines, which is how i ended up here. So, that's a "flathead" engine right? because the valves are next to the piston.. not above it, correct?

Great explenation of how it works internally.

Great video and the cutaway really helps. If you can understand this then you’ve learnt how pretty much most engines work

I am about to attempt to repair an old Briggs And Stratton engine from probably about 20 - 30 years ago and this gives me an incredible idea of how Briggs And Stratton designed their engines so thank you so, so much!

I’m still in shock about the plastic use damn thing must be în pieces for a reason .

Dude should teach challenged kids how to count to ten..

That was really good. Our mower occasionally seizes as you are pulling the starter cord. What is happening with that? Thanks for your help.

Really well done vid

You deserve more subscribers

you sound like a country version of the Joker

Good job young man. We all learned something from the inner screen.

I'm trying to learn all I can about my mower and it's engine, so THANK YOU for this very informative video!

Good video !

Very informative video explaining how the 4 stroke engine works

This made it so easy to understand. Thanks so much Jared!

This was not absurdly long but was extremely informative! Wonderful demonstration, learned a ton

Is it carbureted? How does the engine get the right fuel-air mixture?

Plastic cams!!! Incredible!!!

Very well done except one very important thing ... ignition coil .

One of the best videos I have ever watched on explaining the engine operation.

Great video! This helps me very much try to understand how engines work. I have very little small engine knowledge but recently decided to pick up a wood chipper with a 7.5 hp briggs and stratton horizontal shaft. I figured i'd spend some time and figure out what was wrong with it and try to learn something. The first thing i did was check the oil. It looked new. However when i checked the dip stick, it was extremely low. I drained the oil to find there was very little left. So i filled it to the proper level with new oil. I checked the spark. There is a spark. I changed it just for the heck of it. I also cleaned the air filter and the carburator. Gaskets seemed ok, but not great. When i originally tried to pull start it, it wouldnt pull at all. It was stuck. Eventually i was able to pull it and at that same time, a blade within the chipper cracked off. So i think the shaft was jammed due to the blade getting stuck. It now pulls, but doesnt do anything. it doesnt sound close to starting at all. I dont get sound that sounds like it is starting. I pulled off the combustion chamber and valves. When i rotate the flywheel, i noticed the piston doesnt travel all the way up the cylinder. When i push it down, then rotate the flywheel, the piston comes up about 3/4 of the way. Could the piston not moving all the way up the cylinder be a result of low to no oil? How can i get the piston to travel all the way up the cylinder, as it does in your video when you rotate the flywheel? I have tried lubricating the top of the piston with oil and PB Blaster and spreading it around.. no luck yet. It has slowly rotated counter clock wise as i push it down with my fingers, rotate the flyweheel, and repeat. But never going more than 3/4 of the way up the cylinder. Thanks for the help :)

Great job 👍

I've been working on small engines all my life pretty much but it still makes me wonder who decided to make the cam shaft out of plastic?! I suppose if it's hard enough and is bathed in oil it will last pretty long.

As ashamed I am to admit it I am 45 years old and after watching this video I finally understand how a internal combustion engine works... Thank you so much for making/sharing this video

Did you use just a standard 4 inch angle grinder to build the cut away ?

Thank you!!

Good video, self learning from all the sources available today can make a person wise. God bless you in your future business.

Wow the cam looked really flimsy

Just what I wanted to see

show how it gets spark

I'm building an airplane with one of these

👍👍

Best explanation of the parts and functions of a small engine and its parts! Thank you, man!

does the oil slinger have to be set back any particular way if it is removed?

Very Helpful! One question, how does oil get into the rocker cover and between the rocker and the valve tappet, and does the oil need to go there?

Thank you so much for this awesome visual video.

Thanks for this video - really helps understanding these engines

Just what I was looking for. Thanks!
