Mr. Pete: From one old man to an older man, this was a fantastic video! The technical information was great for beginners, but the historical tidbits and perspective was priceless!
I started working with my hands at a very early age! I tore down a B&S vertical shaft engine at the age of 4 while my brother who was supposed to be watching me took a nap! I never lost any parts and the problem was found and fixed. My parents embraced my skill, and bought me a 4H manual on small engines. As I watched this video I was answering along to all the questions. Thank you for a great video!
This video took be back to 40 years ago when I took the small engine class in school. I rebuilt a 3.5 h.p. B&S and mine was the only finished and running engine. Most of the other kids goofed off and were not interested in learning
Mr. Pete, please don’t change a thing. I come to your channel to learn things including your chatter. You are a teacher and those of us who watch your videos know that. that’s why we are here. Thank you sir.
Mr. Pete, I am very happy to watch your videos on virtually any subject. Most people don't realize the amount of physics and electrical knowledge required in all mechanical repair and diagnosis. I am thankful that a first in class technical school graduate and two decade mechanic still has betters to learn from when it comes to motors and metalworking. I just purchased my first mill and i have had it reinforced that no matter the amount of tooling (just a little jealousy) problem solving is the biggest skill any man can have in a shop. Thank you again for your videos and sharing your knowledge.
Great video. In the 80's my son would find lawnmowers and bring them home.Most were good but no spark and I showed him how to clean the magnets under the flywheel and they would start right up. He really enjoyed that and sold several. thanks for your time. You are one heck of a teacher. Cheers, Lee
Mr. Pete, you remind me SO much of my grandfather. I'm 27 now, but back when I was a kid he used to take me out in his shop and do things just like this. He'd ask me questions and get me genuinely interested in how things work. That definitely helped shape who I am today. Thank you for these videos. It's almost like having him here with me. I greatly appreciate it. It also makes me sad that kids now are consumed by cell phones and video games. and that they won't ever know what it was like to grow up doing things like this.
Thanks Mr. Pete for all of your videos. My favorites are the ones on machining and the field trips but this one was great too. I also like the historical tidbits. Thanks again for sharing your lifetime of knowledge with complete strangers, it is appreciated!
I'm only 36 and love hearing all the details about the different parts. I also enjoy hearing about the fact that you didn't get a power mower until you were 16.
I enjoyed taking things apart when I was a kid. Basically for curiosity and to find the cause of why such things did not work anymore. Was able to even repair some things. No, mrpete222, you are not giving too much information. You do a good job trying to explain what you show.
Another excellent video, I always find myself learning invaluable information from your videos. The historical tidbits and insights into the way things used to be are excellent and the level of technical knowledge and how it is explained is superb.Thank you very much for the work you do and the time and effort you put in.
Mrpete as I have stated before, I was born in 1958. My dad was in pharmaceuticals. Hope I spelled that right. However he was a shade-tree mechanic. When I was 9 or 10 the mini-bike came about. Well I hade to have one! That-said. I spent many joyful hours, rebuilding Briggs and Stratton engines with my dad that we found on the street for junk. He has long since passed however one of many strongest memories is of a father and son on an early, Saturday morning in a small one car garage working with my hands and this I still do to this day today. ~M~ As always, thanks’ for taking the time to make this video
In the 1960's I worked on one of these at school as a boy. This brought back a lot of great memories. As always, your video was simple, straightforward, covered all the points making for an outstanding presentation. Thank you.
I was glued to this video from start to finish. I liked most all the explaining you did that were outside of the original subject. I learned a lot. Thank you very much!
Captive audience. Yes. But for a different reason. No one wants to leave this class. At school there were only a couple of kids who were interested in mechanical stuff the others thought it was a waste of time.Funny, my dad wasnt very involved with his 2 sons but one thing we did together was to have me standing next to him while he took apart our new second hand mower to put rings in it. I learned so much about tools and techniques. I still have that engine .Thanks Mr. Pete
I really enjoyed this video. When I was a kid, I had a go cart with a similar cast iron Briggs engine. I believe mine was a 3 HP. I ran it all around the Bolivar County, Mississippi rural highways and field roads. Even then, the all-iron Briggs engines were very old and were a rarity. I still have an old 8 HP all iron Briggs. I need to get it from my parents' basement and make a video on it. Thanks again for this, it brought good memories and I really liked the old manuals you have there.
From someone that is 19 and never had the opportunity to learn about how everything works. All extra information is extremely helpful, and very appreciated! All of your videos are top notch, now I just need you to adopt me so I can use all of your tools. lol
I was so fascinated by these engines as a child in the late great 60's of old. I wanted a mini bike so bad I couldn't stand it. I was only in the 5th grade, but would make friends with a few kids in jr. high & high school so I could ride on the back of the banana seat. Good memories though I only got to drive 2 or 3 times. I have watched many of your videos over the years.
I have those tools and manuals for the older Briggs engines. They were given to me by a neighbor who ran a lawn mower and small engine repair business. I think I was about 15 when he retired back in the 50's and I still have them. I have the old vibrating tachometer for setting the engine speed also. Loved the video. Mike
Mr.Pete you make a very good teacher even to people well past the half way mark.You go well into the subject yet make it easy to understand,I really appreciate the effort you put into your videos and especially the cut away engine in this video,that must have taken some doing.It is nice to listen to someone who can do the job as well as talk about it,not a white coat know all who doesn,t like getting is nails dirty.
What a natural and brilliant instructor. You obviously cultivated many lucky students. Unfortunately they don't make them like you Mr Pete anymore. How sad
I’ve always admired the ingenuity of the flywheel as used in small engines, and feel they perhaps get overlooked in the pantheon of great ideas. If you think about it, some designs are cooling the engine, helping to facilitate spark, providing counterweight, aiding in timing, and serve as a means to help pull start the whole damn thing -all at once! That is a lot going on by way of a simple compact circle. So much so, that it’s ingenious really.
"Am I telling you too much?" (9:00) Absolutely not! You remind me of an HVAC Controls teacher I had in college. He could talk for hours about electricity, circuits, equipment, troubleshooting, etc, and it was all useful, pertinent information. His class was always lively and I learned so much. Thank you for the informative and entertaining videos!
very nice job.............thanks for all the work you put into this project...........i wish i had somebody show me this kind of illustration when i was 8 or 10 yrs. old. i think i would have started mechanics sooner......thanks again
Very well done Mr Pete! Your teaching aids are superb and it's obvious you spend a good amount of time and thought on them. Thanks for sharing your time and knowledge! Side note: I bet those old Briggs ran, and still run, forever in large part to their simplicity.
This is a very nice video for those folks who have no idea how anything works. I think we have more now than ever before. Unfortunately they do not seem to want to know. This is probably not new information for your viewers. Thanks for the video.
Thank you Mr. Pete. That was a great video. Took me back to power mechanics class in the 70's. The teacher never went into as much detail, though. It's much appreciated. I'm pretty sure that your first engine is a Lausen. I had three of them over the years. One used to power a go-kart, that my mentor helped me build. The man is an excellent machinist and mechanic. You remind me a lot of him.
My dad repaired small engines and that was where I cut my teeth in mechanics. He taught my brother and I how to fix small engines from before I was old enough to go to school. He let my cousin who was about 15 years older than us work on his 64 GTO in his shop during the winters ,but til we got older, my brother and I weren't allowed in the shop while the goat was in there. That just peaked our interest in racing engines and when we got old enough,we jumped in head first into drag racing and hotrods.
yet again Ive enjoyed another wonderfully thought out PREACHING , please don't stop what you are doing . we need more videos like yours , you give more information if not ALL the information NEEDED for inspiring young lad's like my self !!! . thank you again MR.PETE222.from East St.Louis IL . P,S. the LONGER your videos are and when you show TO MUCH Gives me another reason to refill my tea .
You might notice that OVER 4,000 views have been made of this video in just over a week! Everyone watching wants you to continue making videos Iike these! Keep up the good work. And indeed, I watched all the way through.
Air/Pneumatic Governor. Excellent depiction and description of the full function that makes for a complete and potentially running engine. Many of the younger generation who are showing an interest in these old engines will certainly be interested in seeing all of the working components of a 4 cycle engine that you've taken the time to show here. As always Mr. Pete, a great video that is captive. Cheers!! Zip~ p.s. Small Engine Mechanic who appreciates this video and will direct my subscribers to it for reference.
This is an excellent video on small engines. Reminds me of the time I rebuilt a chilton small engine , but I failed. The engine was sold as a parts unit.
So the 2:1 on the gearing was an important point, because the piston will rise to the top twice, to cycle each valve once. Great demonstration... again. My dad went from a push mower to an electric mower. I was very upset, as I wanted a gas engine to play with. Which is probably why he went electric. :-)
Awesome Video, after we fixed an electric handicap scooter I found in the trash my grandpa helped me rebuild a 5hp Briggs engine on a riding lawnmower I bought, he took the time to tell me about every aspect of it, Too bad kids these days dont take as much of an interest in learning about the little things, keep it up :-)
Hi Mr Pete, Love your work, great presentations which will now live on forever. Seems you left in a bit from 21:32 to 23:07 which should have ended up on the cutting room floor, as you start it over again. Keep up the good work :)
Mr. Pete, Absolutely outstanding. My Pop shared much of this with me as he worked on the family car & he & I, way back when, worked on restoration of a 1917 Model T. I passed this on to my son livng in Oregon, the proud father of a young man (13) and young daughter (15). Hope they appreciate what gets them around as a result of seeing this fine video. Have you ever read Matthew Crawford's Shop Class as Soulcraft? More to consider that politicians need to read as they consider what America NEEDS! Thanks for the video. I have subscribed and look forward to seeing more! John Flanagan - San Antonio, TX P.S. You occasionally asked if you were explaining too much. Far from it! Keep up the fine educational skills you have, we need more of the same!
Well, the way I learned it 60 years ago (from my engineer father who built airplane engines for Curtis Wright) it was "Suck, squeeze, pop, phoey!" And I think that now I understand why my Toro garden tractor (which occasionally backfires when I shut it down) is so hard to start. I won't tell you about my use of ether; too embarrassing. And I thought this video was exactly the right length. Maybe a few minutes too short. You go, Mrpete222.
That was interesting even though I knew everything in it beforehand. The mark of a good teacher: Make things you know already seem fresh. You didn't go into points and condenser but that's OK, not the purpose of the video. Few engines nowadays have points and condensers anyway, it is all electronic and you have to replace the whole unit if it fails. Upside is that it does not fail very often, and you don't have the fiddly point setting problems no more. On the other hand replacing the spark plug usually worked miracles. It still does.
Good show and thanks for doing it. I am pretty sure your $1 engine is a Lawson. Cut my teeth on one of those and then graduated to a Briggs NPR6 . Still working on small engines at 70+.
Great video i really enjoyed it. I always wanted to make my own cutaway engine like this... I just may try to make my own. I had a wonderful Father who explained things to me like how engines work much like you do. My father never once complained how as a boy i had lost, broken or mistreated his tools and i was always taking something apart. Anyways im going threw a bout of missing him while watching this video for some reason. My fathers explanation of the four cycle engine has stuck with me and maybe you would get a kick out of it. SUCK---SQUISH----POP---FOOOEY.
I got it as SUCK - SQUEEZE - BANG - BLOW. All internal combustion engines do that. Some do one per stroke, as in the video. Some, like 2-strokes, combine things, with intake/compression and power/exhaust, and some, like jet engines, do them continuously in separate stages (intake, compression, fuel injection/ignition, exhaust). One point it took me a while to get that wasn't mentioned is spark advance. The spark plug doesn't fire at the top of the compression stroke, but slightly before that. That gives the fuel time to burn, so it's ready to push down in the power stroke. As the RPMs increase,, you have to spark sooner and sooner because the piston is moving faster, but the burn rate of the fuel is constant. Advance in the old days was done in various ways, such as using the vacuum generated by the piston or a centrifugal advance using spinning weights that moved out against a spring...faster they go, the farther out they went and the more the spark advanced. Today it's the engine computer that does it. -- Mike
Hi Mr. Pete ; Most people involved with small engines are aware of the problems caused by the inclusion of ethanol to the gasoline to the engines. But most are not aware of the problems caused by the forced removal of the zinc additives (ZDDP) in the latest motor oils, API service SN for gas engines and CJ-4 for diesel. Google removal of zddp and hold on to your hat. Thank you.
That Briggs model N was a heavy duty version of the model 6S. Originally a model N would have had a oil pump. Two types were used. A plunger type or a gear driven type. Briggs sent out tech service bulletins to Briggs repair shops telling repair shops that any time they worked on a Briggs model N that they should remove the oil pump and replace it with a oil slinger like the cheaper model 6S used.
Years ago when ....you can't tell anyone this ! ... I was about 14! For some reason, I put some neat paraffin oil, into the tank, mixed it with petrol. ...not kerosene but what we called paraffin...quite a long chain hydrocarbon. Straight into the tank of a Briggs & Stratton motor. My dads Princess roller lawnmower went like a..... well I had to run to keep up.!! Next thing ....wham! the con rod came through the crankcase. Talk about increasing octaene. Well, he's dead and I soon will be there is the confession. Done at last! I so wish I had a photo to show you.
I like your cut away model. I think I'm going to have to make one to better explain to people what really goes on inside these little engines. Pulling all my good motors apart is getting pretty old! Thanks for the video.
FOR ME THIS WAS A REFRESHER, BUT A VERY GOOD ONE. IT WOULD BE GREAT IF EVERY YOUNG PERSON HAD A BASIC KNOWLEDGE OF THE FOUR STROKE ENGINE. EXCELLENT VIDEO MR. PETE, THANKS.
I wish you still had that Wisconsin Engine! I worked on one of those that was in a 16" guage park train when I was 13. That was in 1959. That same locomotive was running up until 198? Same engine, same American made Loco.
I'm curious as to the function of the pointer looking piece on the connecting rod? Or did I miss something in the video? Another excellent video by the way! I really appreciate you sharing your knowledge and the time to prepare these videos! The only problem with them is they're too short!
continental red seal made a slant cylinder engine, standard equiptment for 1/4 midget race cars. the points were on top, easy to set. Cushman motor scooter engines were very well built, and had a side plate which was easy to remove. the 5 hp are easy to find. the 8 hp and the 7.3 hp are much harder to find and expensive.
Don't let your children play with those old engines, they may become addicted for life, happened to me. I have a few of those old briggs that I still use, sweet old american iron. Thank you.
I didn't realize it till recently that these 4 stroke engines are wasted spark, the spark fires into the exhaust. Notice in your cut away both valves are closed at the top of the exhaust stroke when it would make sense to have a slight overlap to take advantage of the momentum of the exhaust gasses. p.s. Is this true or am I way off base.
Google tells me that Model N is probably a 1.5 HP engine, made between 1940 and 1954: www.asecc.com/data/briggs/engnotes.html Cool engine! This reminds me of the cut-out we had of a Continental C-65 engine (4-cylinder, horizontally-opposed) when I was in aircraft mechanic's school back in the early 1980s. Many an hour was spent reviewing the workings on that thing. You obviously put a lot of work into cutting apart this engine--and I thoroughly enjoyed the review. I still have all the service/parts information for the Slick and Bendix magnetos that we used to work with back then, in an old 3-ring binder in my tool chest. Trip down memory lane to go through it from time-to-time. Incidentally, also have my grandfather's old Machinery's Handbook from the 1940s too, and I go through that from time to time as well. It's fun to see some of his old hand-writing in there, as it brings back fond memories of the times I would hang out with him in his shop when I was a wee lad...40+ years ago. Although you certainly aren't as old as he was, you very much remind me of him. Thanks for all your efforts.
Great video Mr. Pete, it was very enlightening. However, not to be that guy but times have changed, women and girls are allowed to get dirty and be interested in engines too now. I know you mean well, but there really is no reason to only single out the boys for such a good video.
Mr. Pete: From one old man to an older man, this was a fantastic video! The technical information was great for beginners, but the historical tidbits and perspective was priceless!

Awesome Video, after we fixed an electric handicap scooter I found in the trash my grandpa helped me rebuild a 5hp Briggs engine on a riding lawnmower I bought, he took the time to tell me about every aspect of it, Too bad kids these days dont take as much of an interest in learning about the little things, keep it up :-)

Hi Mr Pete,
Love your work, great presentations which will now live on forever.
Seems you left in a bit from 21:32 to 23:07 which should have ended up on the cutting room floor, as you start it over again.
Keep up the good work :)
Mr. Pete,
Absolutely outstanding. My Pop shared much of this with me as he worked on the family car & he & I, way back when, worked on restoration of a 1917 Model T. I passed this on to my son livng in Oregon, the proud father of a young man (13) and young daughter (15). Hope they appreciate what gets them around as a result of seeing this fine video.
Have you ever read Matthew Crawford's Shop Class as Soulcraft? More to consider that politicians need to read as they consider what America NEEDS!
Thanks for the video. I have subscribed and look forward to seeing more!

P.S. You occasionally asked if you were explaining too much. Far from it! Keep up the fine educational skills you have, we need more of the same!
+Jack Flanagan Thanks for watching
A very well made video and useful video. Thanks.

Wonderful presentation Mr Pete! I shared with my teen in hopes he will put down his phone long enough to watch.
kentuckycowboy2 Thanks for watching
Loved this video. I had never seen a flywheel tool like that. Guess I'm the one that broke off that fin.
Doug Rundell Thanks for watching
I have the same older briggs repair manuel I loved reading it when I was a kid
wecanbreathinspace38 Thanks for watching
Very well presented. Thanks !
barkebaat THANKS FOR WATCHING
Well, the way I learned it 60 years ago (from my engineer father who built airplane engines for Curtis Wright) it was "Suck, squeeze, pop, phoey!" And I think that now I understand why my Toro garden tractor (which occasionally backfires when I shut it down) is so hard to start. I won't tell you about my use of ether; too embarrassing. And I thought this video was exactly the right length. Maybe a few minutes too short. You go, Mrpete222.
Daniel Moerman Thanks for watching
That was interesting even though I knew everything in it beforehand. The mark of a good teacher: Make things you know already seem fresh. You didn't go into points and condenser but that's OK, not the purpose of the video. Few engines nowadays have points and condensers anyway, it is all electronic and you have to replace the whole unit if it fails. Upside is that it does not fail very often, and you don't have the fiddly point setting problems no more. On the other hand replacing the spark plug usually worked miracles. It still does.
Juan Rivero Thanks for watching
Great video! I can see you as a shop teacher. Would love to seer more shop type videos (new series maybe? ).
Thanks for sharing your knowledge

Thank you again mrpete222
stevenacarter77 Thanks for watching
Please do more "How it works" videos. Thank You.
Rich G. I will. Thanks for watching
Great video. Just about the only thing we didn't fix at the hardware store was power equipment so I've never torn into an engine!
***** Thanks for watching
Good show and thanks for doing it.
I am pretty sure your $1 engine is a Lawson. Cut my teeth on one of those and then graduated to a Briggs NPR6 .
Still working on small engines at 70+.
Rough Rooster I think u r right. Thanks for watching
Great video i really enjoyed it.
I always wanted to make my own cutaway engine like this... I just may try to make my own.
I had a wonderful Father who explained things to me like how engines work much like you do. My father never once complained how as a boy i had lost, broken or mistreated his tools and i was always taking something apart. Anyways im going threw a bout of missing him while watching this video for some reason.
My fathers explanation of the four cycle engine has stuck with me and maybe you would get a kick out of it.
SUCK---SQUISH----POP---FOOOEY.
builtrodewreckedit Thanks for watching
I got it as SUCK - SQUEEZE - BANG - BLOW. All internal combustion engines do that. Some do one per stroke, as in the video. Some, like 2-strokes, combine things, with intake/compression and power/exhaust, and some, like jet engines, do them continuously in separate stages (intake, compression, fuel injection/ignition, exhaust).
One point it took me a while to get that wasn't mentioned is spark advance. The spark plug doesn't fire at the top of the compression stroke, but slightly before that. That gives the fuel time to burn, so it's ready to push down in the power stroke. As the RPMs increase,, you have to spark sooner and sooner because the piston is moving faster, but the burn rate of the fuel is constant. Advance in the old days was done in various ways, such as using the vacuum generated by the piston or a centrifugal advance using spinning weights that moved out against a spring...faster they go, the farther out they went and the more the spark advanced. Today it's the engine computer that does it.

BigMjolnir Thanks for watching--great comments
Suck..squeeze..bang..blow is the phrase I'll always remember.
Hi Mr. Pete ; Most people involved with small engines are aware of the problems caused by the inclusion of ethanol to the gasoline to the engines. But most are not aware of the problems caused by the forced removal of the zinc additives (ZDDP) in the latest motor oils, API service SN for gas engines and CJ-4 for diesel. Google removal of zddp and hold on to your hat. Thank you.
John C Thanks for watching
Hi Sir.
That first one was a very well build engine. I think it would be worth rebuilding
Marcel Timmers Thanks for watching
That first engine looked to be a lauson . it looks identical to one I own. One no e to work both valves. Oh yea great video.
GREAT VIDEO !!
I NEVER BROKE A FIN BUT I BENT A FEW !
REPLACED QUITE A FEW FLYWHEEL KEYS .
OLD WIPPER-SNAPPER Thanks for watching
Great video. Always loved cut aways' . Just a thought maybe you could do a video on the difference between up draft and down draft carbs.
Donald Barnes Maybe--Thanks for watching.
That Briggs model N was a heavy duty version of the model 6S. Originally a model N would have had a oil pump. Two types were used. A plunger type or a gear driven type. Briggs sent out tech service bulletins to Briggs repair shops telling repair shops that any time they worked on a Briggs model N that they should remove the oil pump and replace it with a oil slinger like the cheaper model 6S used.
Would love to find such an old engine to tinker with!
NekitaNet Thanks for watching
Years ago when ....you can't tell anyone this ! ... I was about 14! For some reason, I put some neat paraffin oil, into the tank, mixed it with petrol. ...not kerosene but what we called paraffin...quite a long chain hydrocarbon. Straight into the tank of a Briggs & Stratton motor. My dads Princess roller lawnmower went like a..... well I had to run to keep up.!! Next thing ....wham! the con rod came through the crankcase. Talk about increasing octaene. Well, he's dead and I soon will be there is the confession. Done at last! I so wish I had a photo to show you.
Wow
Only you would have a Genuine Briggs & Stratton Flywheel Wrench. :-)
TFMTraining true-Thanks for watching
Good job on the video.
KetchumDan Thanks for watching
It was made in May of 1947 according to the serial number. left hand threads on that flywheel nut.
I like your cut away model. I think I'm going to have to make one to better explain to people what really goes on inside these little engines. Pulling all my good motors apart is getting pretty old! Thanks for the video.
W.Co.VIDS Thanks for watching
FOR ME THIS WAS A REFRESHER, BUT A VERY GOOD ONE. IT WOULD BE GREAT IF EVERY YOUNG PERSON HAD A BASIC KNOWLEDGE OF THE FOUR STROKE ENGINE. EXCELLENT VIDEO MR. PETE, THANKS.
ROBERT HORNER Thanks for watching.
I wish you still had that Wisconsin Engine! I worked on one of those that was in a 16" guage park train when I was 13. That was in 1959. That same locomotive was running up until 198? Same engine, same American made Loco.
+Life After Work Thanks for watching-I remember that model of train
nice video
Points and condensers are a total mystery to young mechanics these days. Many have never even heard of such things.
It’s impossible to add too much detail in a “What makes it work?” video. Please continue.
I'm curious as to the function of the pointer looking piece on the connecting rod? Or did I miss something in the video? Another excellent video by the way! I really appreciate you sharing your knowledge and the time to prepare these videos! The only problem with them is they're too short!
William Garrett Thanks for watching
continental red seal made a slant cylinder engine, standard equiptment for 1/4 midget race cars. the points were on top, easy to set. Cushman motor scooter engines were very well built, and had a side plate which was easy to remove. the 5 hp are easy to find. the 8 hp and the 7.3 hp are much harder to find and expensive.
commando340 Thanks for watching
Can you show more about the caburator linkages ...
Don't let your children play with those old engines, they may become addicted for life, happened to me. I have a few of those old briggs that I still use, sweet old american iron. Thank you.
the56bear Thanks for watching
I’m wondering how it threw a rod
Edit: Wow, that external vane governor sounds like a very simple and clever concept
Yes
As a collector restorer it breaks my heart to see this vintage engine cut away😪
I see a beautiful Superwrench ratchet!
Yes you do indeed
Yes indeed
My Dad had a tool talk about cherishing his Superwrench. It is one of my most treasured tools
I didn't realize it till recently that these 4 stroke engines are wasted spark, the spark fires into the exhaust. Notice in your cut away both valves are closed at the top of the exhaust stroke when it would make sense to have a slight overlap to take advantage of the momentum of the exhaust gasses.
p.s. Is this true or am I way off base.
Richard J Lebens Yes--Thanks for watching
Google tells me that Model N is probably a 1.5 HP engine, made between 1940 and 1954:

Cool engine!
This reminds me of the cut-out we had of a Continental C-65 engine (4-cylinder, horizontally-opposed) when I was in aircraft mechanic's school back in the early 1980s. Many an hour was spent reviewing the workings on that thing. You obviously put a lot of work into cutting apart this engine--and I thoroughly enjoyed the review. I still have all the service/parts information for the Slick and Bendix magnetos that we used to work with back then, in an old 3-ring binder in my tool chest. Trip down memory lane to go through it from time-to-time.
Incidentally, also have my grandfather's old Machinery's Handbook from the 1940s too, and I go through that from time to time as well. It's fun to see some of his old hand-writing in there, as it brings back fond memories of the times I would hang out with him in his shop when I was a wee lad...40+ years ago. Although you certainly aren't as old as he was, you very much remind me of him.
Thanks for all your efforts.
Tom B Thanks for watching
AND THERES YOUR DINNER!
Great video Mr. Pete, it was very enlightening. However, not to be that guy but times have changed, women and girls are allowed to get dirty and be interested in engines too now.
I know you mean well, but there really is no reason to only single out the boys for such a good video.
I liked that show
