Hi guys I just wanted to Introduce to you my other Channel "Kirkman's Academy" - which i'm just getting started. It's a go-to channel for simple explanations for hard to grasp subjects such as physics, maths and chemistry etc. Here is the link: www.youtube.com/@kirkmansacademy/videos . Thank you so much for looking, and if these topics interest you then I hope to see you the there. Many thanks indeed. Craig 😊👍
Yes it is ingenious. When the mower engine bogs down in some heavy grass, the governor opens up the throttle and gives it more fuel to try and keep the RPMs up.
Yesterday I didn't even know what a governor was, I just knew "something" was acting up on my snowblower. This video and another one on another channel taught me how the ideling(?) in the carburator worked and what part the governor plays in the whole of it. Thank you from Sweden! 🇸🇪
Great video explaining how an internal governor works. Extra bonus points awarded for having an actual engine cutaway to illustrate. Well done Sir. Well done indeed.
i always thought there was some sort of sensor and microcontroller involved. what a genius mind has created this simple yet workable system. thanks for sharing!
I've had to replace some governor springs that rusted and broke, but I never had the opportunity to open one up to see how it works. It has bothered me for a while, so thanks for this.
Congratulations on making an absolutely brilliant video. Extremely clearly explained, without much a do about nothing. Few videos are this straight to the point and clear.
You are the engine doctor, i never figured out how my generator was able to keep constant RPM, you solved my mystery. Amazing presentation & well done Sir 💯
This is absolutley brilliant. Not to say your previous 2d graphical animations weren't fantastic but this is top notch when it comes to the educating people in regards to the internal and mechanical aspects of machinery and mechanisms, it just cannot be beat. It's a shame that teaching like this has become a "thing of the past". Mentors like you are not as plentiful as they used to be and are certainly not like were in the 60's!
If your lawn mower has a hunting rpm ( revs up and down almost shutting off in a never ending cycle) or when it starts it revs up high to fall on its face and turns off not wanting to stay running .. the carburetor is dirty .. some carbs have a center bolt under fuel bowl on the carb this is your primary jet remove the bolt ( if the bowl stays on that's fine one thing at a time ) with the proper size socket or wrench .. make sure it's passageway that runs through the center and the little hole that's undee the bolt head is clear . Put the bolt back on the carburetor and it should be good to go. ... showed my buddy this some years back ... he would picked up ever mower thrown out on the curb clean the carburetor and sell it to pawn shop... guy was making almost $400 a month doing this at one point.
I started watching it , and when you began to show the internal parts i knew i dont going to understand it because of how difficult it looks like. But your explanation and continuous visually demonstrations helped me to understand it !! Thank you ! ☺️
Absolutly top notch explanation of lawnmower governor works.j This wold have been impossible had you not spent all those hours preparing the cutaway engine. You are a superb instructor. I once saw a video of yours that had a great big model of a chainsaw carburettor for instruction on how they work. You'd never work it out on your own!....that one had to be the best instructive video i'd ever seen!
Great video! I'm no engine expert but I am an (electronic) engineer, and it's good to appreciate the ingenious mechanics that came before electronic control. Excellent demo model you have there! Thank you for sharing it with the world 👍🏻
wow, what a fantastic explanation ! the cutaway sections are amazing. I've been trying to fix my lawnmower for ages, your video has helped me sort it - thanks !
Mate, Thank you very very much for your explanation! Your video's always have the right amount of information and the way you explanate it is spot on! Look forward to your future video's!
What a great way to do a tutorial! Brilliant! Of course, I'd be fascinated to see the teardown and work done to produce this masterful work of art, so I'll watch that, too. I'm sure we'll see it in action again, in all of its glory. I think you covered how the governor works before, but this makes things ever more clear. Fantastic and Thanks, Mr. Craig. Edit to add: You forgot to add the link to *Old Rusty Lawn mower Transformed Into Something Very Different! (An Educational Artifact)* so I found it in your Videos page.
@2:46 - The plastic Gear- I've always wondered what it was!! Silly me I thought it was the safety device when one hits an above ground root or something with the blade- it shuts off the engine. Thanks. I take apart mower engines for fun and Aluminum during the Winter. Thanx Mate!!!
Thank you. I never understood what was going on there, especially having grown up when lawn mower engines had a separate throttle lever that we controlled. I had no idea all this was going on and I didn't know what was involved. And I've worked on cars for 40 years, lol.
I have a small diesel engine I need to govern to give me more power when the electrical load increases. This video has given me ideas on how I can retro-fit a mechanical governor. Nice to know these mechanical guvnors still exist. Had a hard time searching for them online.
That's a bad idea. You want that engine to tun at exactly 3600 RPM to give the correct Hertz (60Hz in the USA). Increasing the RPM will increase the Hertz and damage your electrical equipment. If you have a 4 pole generator head it will only require 1800 RPM but you probable have a 2 pole, not a 4 pole.
That was an "Oh!" moment for me. Got myself two old Briggs & Stratton mowers to repair, one's running now but sounds like it revs way too high and inconsistently, so this is a solid lead. Wasn't really aware how governors work on engines. Thank you. The other one probably has a broken spark coil, no spark from the cable connection, and but a drip of oil on the dip stick so probably received no maintenance :(
It is the same on gas engines that were used in stationary applications or on heavy duty trucks with PTO’s. The only differences was how they were run. Some ran directly off of the distributer and used vacuum as a reference. So it is mechanical/vacuum governed. Most actuations of the throttle plate directly were done by vacuum and simply not by levers. Same concepts apply though. Others were vacuum only like many 1bbl carbs. They used manifold vacuum reference to open or a close a secondary throttle plate to control the rpm. This was set by spring tension on a diaphragm. The other way is mechanical entirely similar to the modern lawnmower engines you showed in the video. If it was a remote system it simply used cables as reference speed. These same concepts were applied to create the earliest cruise controls like the speedo-stat and the earliest production cruise control Chrysler’s Auto-Pilot. Very cool stuff that very smart people figured out!

Great video no loud introduction straight to the point and no music while you were talking
Thank you so much

What can I say, absolutely brilliant demonstration, was always wondering how the governor works, thanks very much greg
That sir is one of the BEST descriptions of that system I’ve ever seen. 👍🏼🇨🇦
Wow, thanks! I really appreciate it. Craig 👍👍👍

Thank you so much for your kind feedback. Craig 👍👍👍👍
The best explanation i’ve seen in years. Ricky Huntsville, Ala.
Thank you Ricky for your kind and motivating feedback. Craig
Well explained. Short and to the point. No waffling, no interference from background music. Well done!
i always thought there was some sort of sensor and microcontroller involved. what a genius mind has created this simple yet workable system. thanks for sharing!
Right on 'dynamic' demo. There is nothing quite like a dynamic demonstration, and your's is Well Done.
Thank you!
Thank you kindly! Craig 👍
I've had to replace some governor springs that rusted and broke, but I never had the opportunity to open one up to see how it works. It has bothered me for a while, so thanks for this.
I couldn’t find a video that explains it as clearly as this, thank you so much!
You're very welcome! Thank you 👍👍👍

Thank you so much for your kind feedback. I really appreciate it. Craig 👍👍👍👍
Perfect explanation on how the governor system is supposed to work. Thank you!
Thank you 👍👍
That was an excellent explanation of how the governor works.
You unlocked a lifelong mystery for me. Thanks
On my victa lawn mowers the governor operated according to strength of cooling fan blowing on a sail type lever .
Thanks guv .
Very well explained thank you. Strange how all these mechanical systems work on negative feedback.
Awesome thank you 👍👍👍👍

Wow. Thank you. I really appreciate your kind feedback. Very motivating 👍👍👍
Been trying to find out how these work for years. Thanks for taking the time to explain this.
If your lawn mower has a hunting rpm ( revs up and down almost shutting off in a never ending cycle) or when it starts it revs up high to fall on its face and turns off not wanting to stay running .. the carburetor is dirty ..
some carbs have a center bolt under fuel bowl on the carb this is your primary jet
remove the bolt ( if the bowl stays on that's fine one thing at a time ) with the proper size socket or wrench .. make sure it's passageway that runs through the center and the little hole that's undee the bolt head is clear . Put the bolt back on the carburetor and it should be good to go. ... showed my buddy this some years back ... he would picked up ever mower thrown out on the curb clean the carburetor and sell it to pawn shop... guy was making almost $400 a month doing this at one point.

Amazing video! This is the first time I feel like I UNDERSTAND how the governor works 🎉
Absolutely fantastic explanation. Thank you for making this video.
My neighbour fixed his mower and now runs flat out constantly, I can now tell him what's wrong! Thanks again 👍
Great explanation
So glad I found this before I started messing with my cement mixer!
Thanks I finally understand how spring tension on the governor arm affects the position of the throttle
Great work. The cutaway engine makes things very clear.
I'd heard of a governor spring, hadn't a clue what it done. Now I know. Good video.
Great video! I'm no engine expert but I am an (electronic) engineer, and it's good to appreciate the ingenious mechanics that came before electronic control. Excellent demo model you have there! Thank you for sharing it with the world 👍🏻
Thank you for your kind feedback. I really appreciate it. Craig 👍👍👍
thanks for video . I have been interested in knowing how that works for along time .
Comprehensive and linear explanation. Very well done.
Many thanks! 👍👍👍
wow, what a fantastic explanation ! the cutaway sections are amazing. I've been trying to fix my lawnmower for ages, your video has helped me sort it - thanks !
This helped me so much. Now because of you I understand how governors work.
Thank you so much for your kind feedback. Craig 👍
Brilliant. I always wondered how the governor arm moved. I had no idea there were a shed load of gubbins going on inside to move the arm.
Absolutely. Thank you 👍👍👍
Brilliant explanation and cutaway to explain it all. thank you (Greetings from Australia)
You're very welcome! Craig
Awesome I'm 39 and never had a clue how that worked
Thank you 👍👍
Mate, Thank you very very much for your explanation! Your video's always have the right amount of information and the way you explanate it is spot on! Look forward to your future video's!
Thank you for your Kind feedback. I really appreciate it. Craig 👍
Fantastic video!!! Very clear and concise. I always wanted to know how the heck my mower controlled its throttle.
What a great way to do a tutorial! Brilliant! Of course, I'd be fascinated to see the teardown and work done to produce this masterful work of art, so I'll watch that, too.

Thank you so much 👍👍👍
Awesome!!! Thank you!! Nothing else I've seen or read (including the Briggs repair manual) explained that internal thing so clearly!!!🤩
Fascinating, Thank You ... Those flimsy looking plastic bits are horrifying though!!
Yes, you are right
Excellent practical application, clear and concise.....
Thank you brother from across the pond that helped me a whole lot
Absolutely brilliant!!! I have always wondered how that works. Thank you!!
You are so welcome! Thank you. Craig 👍👍👍
I didn't know that...great explanation...great teacher
Delighted, thanks very much 😊
Couldn't ask for a better explanation
Exellente demostracion Sr. Repair. Gracias por compartir su conocimiento.
Thank you for your nice feedback. Craig

Brilliant I've been trying to set my mower up all wrong
Excellent video straight to the point and very well explained.
Thank you so much 👍👍
Brilliantly explained
Thank you. I really appreciate it. Craig
Wow this is an amazing video. Love the cutaway too. Have always wondered how these worked!
Thank you very much! I really appreciate it. Craig 👍👍👍👍
Very well done. Very simple and informative. Thanks for posting.
Thanks for watching! Craig

You put that old engine to use. "I knew you would"! 👍
Stay well, Joe Z
Fabulous explanation and visualization! Thanks.
Great video explaining the governor of a lawnmower engine 🎉
Thank you 👍👍👍👍
That was a perfect explanation ! . . . I've always wondered how a gov works. . Thank you.
Very well done tutorial with actual working view if the governor system. Narrated and filmed quite detailed yet easily explained! Great video!! 😊
Very helpful thank you for the time you put towards educating people like myself
Excellent setup and great explanation.
Awesome video ! Thank you for the visuals and clear explanation.
Great cutaway engine Craig! Knowledge is Power!!
Excellent explanation thanks very much. I often wondered why my mower qas hunting up and down revs until warm.
Thank you 👍👍👍

the greatest explanation that i never knew i needed. so awesome
Thanks. I assumed it was some sort of centrifugal gear coupled thing but now I know exactly how it works.
Otima explicação prática do governador...
This was absolutely excellent.
Thank you so much. 👍👍👍
Excellent demonstration..well done ❤
Thank you so much
This was a great explanation sir. Thank you for sharing this video ✌️🇺🇲
