Miniature FLATHEAD Four Cylinder Engine Assembly & RUN! 

Engines are normal sized he's just a Giant

Everyone thinks working with multi-ton parts is hard but after a lifetime of machine work I can tell you the small parts are the real challenge. I am amazed at the level of detail in this assembly. Very seriously impressed, this is watch maker level precision.

Didn't even know there was working mini model engines. Awesome work.

В детстве лет 20 назад мечтал что в игрушечных машинках будет такой настоящий двигатель в миниатюре🙂

I love how, because of the last video on mini engine building where a ton of people were questioning your timing of the cams, you show the TDC/timing marks/process on this one. :D

Wow an actual miniature version of a real engine! All the other ones I've seen are not in my opinion because they are not fired with a spark plug and do not have an oil system. This engine is way cool!

Love it so much these little engines are so cool

This seems like an incredible way to teach young children/ novices or even just people who want to learn the basics of engine mechanics. I mean if you can understand how this works you’ll be less likely to get ripped off by a dodgy mechanic 😂

I find it absolutely delightful that this engine actually uses spark ignition instead of glow plug ignition.

I'm way more impressed with this than I thought I would be.

A lot like the motor in my 8N tractor,just a little smaller! Dig those mini spark plugs!

A wet liner, wet sump, sidevalve engine. Brilliant. Lap the valves, fix the front seal and a bit of carb work and it should be a winner.

You probably get quite a bit better behaviour setting the ignition timing to 28 degrees BTDC. This finally looks like an engine that is designed with doing serious runtime in mind, Like the centrifugal cooling pump and the geared oil pump.... Hate the fact that they are belt-driven: No oil pressure alarm, no cooling water temperature alarm, so a snapped belt will lead to near immediate selfdestruction. Solution: place a motion detector on either one of the pumps, that shuts down ignition if no RPM is detected. That will with 100% certainty be an engine saver, because those belts ARE going to snap... The valve adjusters also are most likely going to lead to trouble, and to remove them, the head needs to come off or there is not enough clearance to move the valves.

Впервые узнал и увидел...это просто Класс! Удивительно то,что всё миниатюрное..маленькое,а главное что этот двигатель..работает! Спасибо за увиденное чудо! Успехов Вам и здоровья!

These tiny engines always suprise me with their build! And so do you!

These videos really helped understanding how engines work. Aside from that they're just really cool, keep it up!

Никогда не ремонтировал двигатели!За несколько минут понял как устроен!Большая вам благодарность!

This is the best thing RU-vid algorithm has ever ever put as a suggestion for me. Thank you!!!!!!! On my way to buy a kit right now!!!

That is one of the best sounding miniature engine I’ve ever heard. !

This knocks the spots of these Toyan engines imo, the wet sump, the plugs etc make it a real 4 stroke. I’d like to see this one in an RC car, being a side valve engine, a body to suit the era of when that engine was in production (1940’s 1950’s) style bodywork.. It’s a shame there’s such a limited run on them, I should imagine that they’d be snapped up!

Such phenomenal toys we have today. When I was a kid I got to play with dirt, bicycle was used for getting to school and back. We used to throw a trash can lid like a frisbee before the frisbee was invented. Built a go-cart, couldn't afford a gasoline engine so we used a electric bench grinder motor. Worked great until the extension cord ran out of range. We only dreamed of stuff like this.

I loved building models as a kid but never in my wildest dreams would I have done that one if they even existed 50 years ago. Very cool!! Actually I looked at the prices and even if they did exist my parents would never have bought me one!

This is so impressive. It's like the Rolex of mini engines. I enjoyed this very much.

A wonderful video! No stupid music, just step by step assembly of the engine. Thank you!

Not gonna lie! This thing had the best idle I have heard in a while! It was running bad, I hope you tune it out and show final results! Great video as always Johnny!!

Fascinating, thanks. I like that it has water cooling too. Amazing! 😊

Mad respect for your manual dexterity!

The I interesting thing about the flathead is that it runs. Nobody should kid themselves that it runs well, or is fuel efficient. Beautifully made model, though... no getting away from that!

I love these mini engines! I think they're so cool!

what a engineering bro!! The video is for just 15 minutes bt your hardworking is hidden! Lots of love from Bangladesh. ❤️❤️

Yo that thing costs $1000 who in the world would buy that (aside from RU-vidrs cuz obviously they make money off of it

My Dad would of loved this. He was into anything mechanical, especially engines. Thanks for uploading this!

my old sailboat has the grown up version of this, they called it an Atomic 4! what a great engine design, 62 years later and still runs like it should.

This is truly a collector’s item, good job 👏 👏

Tudo da par ver que não e tão difícil amontar um motor mais difícil e sempre conserva ele em dias Excelente trabalho 🎸🎸🎸 Brasil BR

I love that it uses crankcase oil instead of premix and actual spark plugs!

Should definitely make some clear covers for the side of the block so you can see the crank and valve springs :)

This is something that EVERYBODY must experience in school, university, as a personal hobby, collectionist or educator. This is top learning with a 'toy' that IS NOT a toy. This gives a clean idea what technology is. I could simply assemble it and have it as a decoration piece that is dismountable or make it WORK as a classical engine. I can't explain how important this is. Schools must provide these experiences, with lego, THIS, block bending, block motors from lego and all other things. Learning should be FUN again. Yeah, make learning FUN agan. :3

Even tho the engine runs bad, its still fun and satisfying to watch this works, i'm so happy to watch this video today

Love these mini engines so much. So cool to see these tiny parts run. 😍

The alignment and balance of the front pulleys is amazing.

As somebody who played the Car Mechanic Simulator games far too much I feel like at home watching those videos.

Very nice, very impressed by your editing and the beauty of the engine.

I have only one word to describe this, WOW! My first time here and I’m blown away and have enjoyed watching this short more than I could imagine. Keep up the great work.

I'm not an engine person at all, but this is pretty freaking awesome!

Perfect engine! Now get the car and the action figure 😁

Awesome content! Your videos are always so pleasant to watch! 😀 When assembling this engines, you think you could, somehow, make the way the fluids and gases flow through the engine clearer? 😁😁😁 Although you said it runs bad, I loved the sound and the look of the engine. Thanks for showing it!

Such an awesome piece! Love the content, keep it up!!!

Pretty cool! I have almost the same real engines in my 1948 Willys CJ2A and my 1952 Ford 8N tractor. Good to know even a brand new flat head 4 banger will pop at idle...lol.

Just by watching this video and a couple of your other videos, I can now certify myself as a mechanic.

Супер! Молодцы! Отличная вещь!

It really looks like your coolant stopped flowing and was boiling in the engine toward the end there. That pump might not be spinning fast enough/got airlocked at some point.

I was amazed. miniature like this is so rare. Thanks for sharing this.

Anyone notice how normal sized the parts look until his hands are in the way? Pressing the wrist pins got me. Great video. Loved every second.

I'd like to see more builds for or with these engines (like the cars or mini chainsaws, or perhaps a mini supercharger would be cool).

Great video brother. This engine looks impressive apart from the leaks. The brushed starter motor always is a problem.

I really enjoy watching i'm now on my basic training as a mechanic very nice one I can say

It is so helpful and educational how components of an engine assembled in a very vivid way

The engineering of these mini kits is incredible...👍👍👍

I would just like to mention, great build, but because you have set the spark plugs to 15* before tdc, the engine has low rpm and misfires, as you can see from the exhaust, flat head engines are meant to have around 4*-10* before tdc. But still, great build.

Verdaderamente INCREÍBLE. Felicidades 👏 👏 👏

This was mesmerizing to me. Great video. It brings out the gearhead in all of us!

Simplesmente linda obra de arte

I think putting together this miniature would make me feel like I could conquer an actual size one.

Wow i never knew this was a real thing? I'm sold!

Actually works.. Just disable the real time protection in Setting. Wasnt sure that it would work .Awesome bruh..

I would love to get a kit like that and put together an engine. At 11:25 I think it was, when you put the side crankcase covers on.. I let put an awww, when I saw they weren't see through. That would be an awesome improvement imo.

That is probably the coolest thing I’ve ever seen and now I want one. I also wonder if they make them in diesels 😯

The description of this engine on the Sterlingkit website is just too funny!

Neat engine, crazy impressive skills!

Interesting the differences between this and the Toyan engines, I wonder why they went with a flathead design? Normally flatheads aren't stellar for power or efficiency, but it probably will run for a very long time! I really appreciate that this has actual spark plugs and ignition system, as well as an oil system, pretty cool! I hope you can get it running proper. Looks like there might be some design improvements to be made.

Yo i like how the bearings are kept from spinning in place, theoretically, by some sort of hardware. Im sure some ungodly amount of torque can get them to spin but this will help prevent that. 🤘🏽✌🏽👍🏽 awesome vid as always

This little beast sounds 100 times better than my single cylinder bike!

Finally an engine with its own oil !!! I’ve waited ages to see this!!!

Too cool! I love it. I did assembling a plastic model back in the 80 but this one is one the best.

Hey Johnny, Hadn't seen you for a few weeks, perhaps. Good to see another miniature engine coming together. But I wanted to ask, is that brand Cison any good? Unless lapping the valves isn't an option, it was sounding kind of rough. Anyhow, good to see you back. 🏎

OOh that scraping when you turned the crank shaft 😁 Had me worried 🤣

Вот это "игрушка" для взрослых дядинек ! Прекрасное исполнение исходных комплектующих . И какая сборка ! Мастер ! Отличная лабораторная работа для обучения двигателистов в колледже !

These are so much fun to watch. I learn so much. Plus I like when you machine your own awesome parts. I'm also still excited to see what you do with the V8 . Having a nitro RC car since I was a kid. I think the Schumacher 21 on road/off road truck. I haven't messed with it in years, since my uncle passed. He's the one that had gotten me into this and knew everything about it. I always say he would have LOVED this channel and probably would try to shove one of these huge motors like you did lol. Take care buddy, can't wait to see what you do next

These engines look so satisfying to build, might have to get one

Wow that was very enjoyable, I was excited when you started it. 😮😮It was the only part i was looking forward to the most. Keep up the good work!

Amazing, truly amazing!

Another great tiny engine build Johnny could you make a pulley and bracket for a DC generator or an alternator to power the engine so it's not entirely relying on the battery to keep running?

Интересно на что ставятся такие миниатюрные двигатели?

Lo felicito mientras más pequeño más difícil y más grande más fácil aparte de la tecnología qué belleza

TNice tutorials is just the pick up I needed, thanks man

Ever thought about making a mini muffler/fart can and exhaust system to make one of these sound different? Sounds like an open header 4 cylinder but if you threw some small scale back pressure with a longer exhaust at it would it sound like a legendary 4 cylinder engine? Could probably even make a tiny bov for the boosted ones.

Impressed by the fact it uses metal or "real" piston rings, not to mention two of them per piston. Ive seen some of these small engines that use an oring for a piston ring...heck nitro rc engines, which is what I have a few years of experience with, don't even have piston rings of any kind

The miracle one💪 I learned a lots

soone who does not get complex instructions like..At all, tNice tutorials was simple and clear for to understand. Thanks dude.

Would this be a viable engine swap for my miata? I have a feeling it might be too big.

That is a cool engine kit. Is that for display purposes or is there an actual application for it's use?

Man i can't wait to get me one and put it together this would so help my mental health 👍

Incredible!🤌❤️

That's a nice little engine, right up my street! There's a much better way to set the timing though, as finding TDC with a clock like that isn't the greatest, and could easily be a few degrees off. Use a degree-wheel on the crankshaft, and a pointer, zero the pointer with the piston 5mm or so down from TDC, the rotate the crankshaft backwards until the piston has gone down and back up again to 5mm from TDC, read the angle, then turn the crank until it's halfway between the angles you've measured, et voila! accurate TDC (or BDC if needed). it's way simpler than I made it sound though!

Reroute the exhaust up, and put clear parts on the lifter and crank doors. Also this engines looks like it needs a turbo or a super charger.😎

works, keep up the good work man

I could not stop watching too bad they don't make them like that anymore I used to be able to work on my own car back in the 70s

Love that engine, I want one

Hardest part of the whole project? Paying for it
