This is a Honda G150 that I got from the metal recycling yard along with the Compressor head that I did recently. This engine took a real beating in its past life, Hopefully, I can save it and give it some more life. If not at least give it a beautiful funeral.
I hope you enjoy the video.
If you have any suggestions for improvement, or compliments share them below!

More info on the engine in general.
Japan’s economy rapidly expanded throughout the 1960s period of high economic growth. Development of the country’s domestic infrastructure saw steady growth, while people’s lifestyles also greatly improved. By the 1970s Honda was setting its sights on markets outside Japan.
Honda had been exporting its power products since 1963. However, it was now beginning to formulate plans for what it called a ‘Million-Seller Engine’ (ME) for the international general-purpose engine market, which then totaled around 10 million units. With an annual production output of about 200,000 units, Honda was now planning to achieve annual sales of a million or more.
At the time, American-made general-purpose engines accounted for approximately 80% of the global market. These engines took advantage of the merits of mass production to sell at low prices. Yet problems persisted in terms of durability and maintenance.
Then, in 1977, Honda released its G150/200 general-purpose engine, the first developed under the new ME concept. The G150/200 incorporated new materials and new designs. With features like an automatic shutoff function for when oil volume was too low, a maintenance-free CDI ignition, a decompression cam for easier starts, and a kill switch for quick stops in emergencies, this engine successfully overcame virtually all of the weak points that plagued mainstream engines.
The G150/200 soon won a highly favorable reputation throughout Southeast Asia, where it became known as the red-and-white engine that steadily sold even when not displayed in the storefront, and found use in a wide variety of applications, including as an outboard motor and for powering pumps.
The engines developed under the ME concept eventually became a full lineup, and finally achieved the goal of a million units in annual sales by 1982. While this was only a tenth of the global market, it successfully showed the world Honda’s superior technological capabilities and vision.
Next on the horizon for Honda were lawnmowers for the US market. First, local needs were thoroughly investigated with detailed field surveys. Technology teamed up with novel ideas to overcome problems and succeeded in creating a new line of high-quality products that offered excellent durability and ease of use. Honda’s hallmarks of quality were now extending to the United States.

I have this exact motor on my mums lawn mower..It was bought new in the 1970s.I bought a new carb for it off Amazon, changedthe oil regularly, & painted it up, & is still running perfectly.Never had the head off.I think these are rated at 3.5 hp..Mind you, when operating, it never goes over about 2000rpm.Oh ,& the oil leaks out of the crankcase where the governor lever is attached.There is no oil seal.Probably where this engine got all its mess from.Nice work.

Don't use a punch to install bearings! Use a block of wood or an Arbor press. Also you need to torque the flywheel nut otherwise you risk the nut coming loose and the engine will not fire or run like crap because it's out of time. The flywheel can shift on the crank and break the woodruff key if that nut is not torqued correctly causing a no start condition!
copy that
I have an old Briggs and Straton lawn mower engine that I stripped and cleaned like this. The idea was to turn it 90 degrees to run like this Honda. My only draw back is I can not find piston rings for the engine. Great job with the little honda engine💪 Inspire me to go and finish my project. (Need the engine to drive a wood mulcher machine for branches and twigs)
It's nice to see an old engine saved from the scrap yard and brought back to life
Simply fantastic video.
I teach precision measurement and metrology and just really enjoyed your approach.
Well done indeed!
So nice to see craftsmanship!
Very nice job 👍 that thing will be good for another 70 years now. !!
That's the plan!
Great job, you have inspired me to do this to an old Honda job site compressor it's a bit larger but the same procedure, thanks for the inspiration. Cheers from Jacksonville Florida 🌞
Glad to be of help my friend!
Bueno al final lo conseguimos, tu el trabajo y YO mirando.
X favor en Español, gracias..
Holly crap, you made come some very good memories from back in 1994 when I used to fix this kind of engines, this model in particular is almost indestructible unlike the Briggs & Stratton and the Tecumseh.
Shit I'm getting old! 😂😂😂
Hahaha aren't we all??
@@AJRestoration 😂😂😂🤣🤣🤣
I just fixed up an 1930s lauson engine. It didn't run for 60 ish years. I'm only 13. 😂
Looks brand new.
my honda G150 is the other way around. it had compression but no spark :o
Good job
Thanks
Nossa que coisa linda de se ver!!!
Puxa, eu colocaria esse motor em uma base e ligaria ele de vez em quando só pra ve-lo funcionar!
Parabens!!!
Hola estas haciendo un trabajo de Relojeros, profesional 👍
Good afternoon from Southeast South Dakota
Excellent!
That one has seen a lot of bad fuel, indeed, maybe mixed in with kerosene and other things to save money.
Valeu AJ! Tmj. Thanks
The parts sounds lake a Church bell wen you take hoven parts 😂😂
Good job
I have this motor in my dad's back yard its its like brand new
The yellow staining is from the oil. Full synthetic oils do this if the engine is not run for long periods of time when running. The red on the pistons is a coating. To help the piston move in the bore easier. You can see where it's been worn off on the skirts of the piston.
Klasse Dankeschön für das Video
Like this...
I really enjoy the longer videos (part 1 and 2). You are doing a great job keep up the good work
Its a really good video. I have a honda f400 and it used this g150 engine. I study a lot of thing by this video. Thank you.
well done
That looks mint now, nice one
That’s hilarious because some guy brought in the cover to get it restringed and it was from this engine 😂
Brand new again. Thanks, great work
Thanks again!
comprestion test also it will tells a piston ring is leaking or the piston it’s self or crank a crank shaft bearing
Goeie môre AJ. Man daai motor lyk so mooi jy moet somer my copy van n Honda grassnyer ook so mooi kom maak jammer jy is so ver van die Oom af. Mooi rustige nag vir jou
Для отмывки карбюратора лучше всего использовать Methyl Acetate. Просто замочить и всё само отвалится. Чистить щеткой нет необходимости.
Привет из России.
Amazing.....
what a bouts a compression test it’s will tells if a vale is leaking or a gasket or a cylinder it self
Get yourself an ultrasonic cleaner. Insane time saver!
Good job 👏
To answer a question that was asked during the video The yellow stain on all the parts internally is from a lot of gas getting into the oil and it being continuously run or otherwise known as varnish
Yep, though, it seems that the stuck valve and some of the build up on the top of the piston and the stuck ring and the discoloration on the piston skirt are signs of probable overheating.
Keren bang
I would buy a set of those gas can / fan shroud decals if they were sold (G200 resto for me).
it’s a carberater where the gas go in to starts the engines if it blocks it will not going to starts at all
where do you get your replacement stickers/decals?
Exquisite craftsmanship👍
cool beans brother😁👍
Generally staining inside the engine is from not changing the oil regularly.
Идеальная работа! Прошу помочь, помогите мне. Мотор honda g150, но внутри не шестерни а цепь. Подскажите как поставить метки на цепи и звёздах распредвал и коленвал. Спасибо вам за вашу красивую работу и красивое видео!
Эти двигатели были практически вечные. Работали на любом, самом плохом топливе. Но это не нужно обществу потребления...
Wel AJ nog n perfekte restorasie van jou jy verstom my elke keer doen so voort
Very good ❤
2:44 that is the exact same carb for the GCV 160! 5.5. a little different but basically the same
Correct they are basically the same
I actually have one of these engines and needs repairing
Mario Mota • 2 giờ trước
very good
Awesome!
My question is what were they running that thing on gas or wood ash I mean I've seen some bad carbon in my day but never anything like that it looks like and this is just from my experience but the only way I can see anything like that happening is if it's run without a air filter for a long period of time near some place that deals with a lot of sawdust or wood ash or really anything like that even if it was a lawn mower at some point and was just continuously munching on grass
Quá tuyệt vời. Bạn cho biết bạn mua những máy sơn làm mới này ở đâu được không?
Beautiful work done here.
Thank you very much!
Τέλειο
hello superb video what I was looking for thanks to you, can you tell me the Rodoir de cylinders or advise me thank you in advance (translat sorry)
bonjour superbe vidéo ce que je cherchais merci à vous , pouvez vous m indiquer le Rodoir de cylindres ou me conseiller en vous remercient d avance
Mantap bro
If that carb stem just broke it triggered the hell out of me because I overtighted mine one time and it snapped off below where you can get it out. Had to use automotive two part glue just so it stays in forever cuz fuck it and fuck those carb stems lmfao.
Its a total pain hahaha
Great Work as always!!👍
Thanks again!
I do not think it overheated but I can't be sure unless I can get a good look at the cylinder walls to see for any discoloring however that would have to be done after a very slate honing to take off the very surface to see the true extent of any damage that may be there and due to the fact that the bearing journals do not seem to be discolored indicates that it was not overheated I really think it was just run with a lot of dirty fuel and I mean really dirty fuel like varnish that's what happened most likely
KALAU MESIN KUBITA GS 300 APAKAH ADA KAK ATAU APAKAH MASIH ADA STOKNYA
Best❤
That appears to be a "kool-bore" aluminum block, those really shouldn't be honed due to the "glossy" looking surface being what seals against the piston rings, it did look like where were a few deep scores, so probably better to hone this one in particular, but the "kool-bore" blocks in general should not be honed.
so is there somewhere that i can get parts for this motor i have the same one with no spark?
I have no idea, maybe Ebay?
Hey can you help me i have a same honda and restored it but ghe ignition coil was not working so went to buy it and i bought a used one but when i installed it doesnt work how do i check if the coil works,and what is the gap between the points?
where did you find the new airfilter and exhaust?
Airfilter can still be bought at some of my local lawnmower service centers. I had to order a new exhaust one online.
This is great ! I'm restoring exact the same engine right now. You might be able to help me out with something ... My engine has no contact breaker, but was equipped with a CDI. (electronic ignition component), and I don't have spark. Coil is replaced, condensor, CDI and spark plug also.
primary coil wire is connected to condensor, CDI and kill switch (which is tested), but still no spark ...
I'm wondering what I could have done wrong... Anyone with ideas, feel free to respond !
The magnetic pickup sensor on the internal flywheel might've burned out
Excellent job! Can you tell me what red code paint it is?
I will have to have a look, I know its name is signal red on the container. Not sure if it has a color code.
Чисто тот самый перекуп
you 've got luck that the screw thread in the carb body wasn't correded at 27:00, that is a weak point.
Yes they usually are quite corroded.
There’s a handful of good restoration experts on here and AJ restoration is one of the best love seeing these turn out good in the end. Thanks for another cracking resto keep em coming
AJ restoration is a great job you've shown to us that gives me an idea how to make it new again.Thanks for sharing
와우~~~
この人すごい技術ですね
How do you know eyeball was a winner. Point gap also effects timing on those.
It does not affect timing, timing is set by the key in the flywheel, and these engines do not have any timing adjustments.
@@AJRestoration The later the points open, the later the spark comes and retards the timing. The earlier the points open the sooner the spark comes and advances the timing. A wider point gap will make the points open early.
@@AJRestoration Also you can buy offset woodruff keys to adjust timing. Not that you need to.
some screw need torkmeter rench
Do you have a link to where I could find all the Honda g150 & Honda g200 stickers/decals?
Unfortunately not, I had to make my own.
Hi where did you get your g200 fuel tank thank you
It came with the engine
I like engine
What’s parts are new to this rebuild?
👍mantaappp
I don't think the engine overheated,I bet it ran with old oil for a long long time. that yellowness inside the engine is quite common in old engines even if oil been changed at right interval..
Nice work on the resto.
We're do u get the decals from?
Im curious, do you ever have to watch your videos back to see how parts go back together?
Actually yes I do have to watch some parts to remember where things go haha.
Once you do this type of stuff more than 5 times (small engines) you can pretty much just look at a particular nut or bolt and know exactly where it goes. Even if you've only worked on one small engine ever multiple times if you've torn it down to the block you will always remember where everything goes. I even have memory affected by my epilepsy so it is pretty easy. Don't even lay mine out anymore just throw them in a pile while I'm working. Lol
Why when I do something like this I can't remember where parts were placed ?
У меня к вам один вопрос, так называемый шланг-форсунка выполняет какую-либо функцию на двигателе мотоблока??
So... what was the discoloration on the piston?
Really old oil, and probably additives.
I am currently also working on a G150. It runs pretty well, but the fuel shut off valve is very leaky. Did you restore yours? Or do you maybe have a link to a good one online? I just cannot find the right one.
hey i know im late did you figure it out,they are really cheap online where do you live?
@@miroslavkrajisnikovic4563Germany. I realised, that I just needed the 22mm bulb that sits at the bottom, unfortunately the nut securing it was bent. We managed to get it tight by using Teflon plumbing tape. If you've got a link to a Shop, i'd appreciate if you sent it to me!
@@LukasM297 This is aliexpres

I had a problem with that valve and i bought it from ali and its good but my ignition coil is dead so i i am trying to find a good one.
can i please ask what torque you do the head bolts up to ? Currently doing a similar rebuild and not sure what to do them to
You will find everything you need in this workshop manual.

@@AJRestoration you're the man! Thank you
if you were seriously going to restore that little motor, you would’ve gotten shit ton of new replacement parts for it
If only new parts were available hahaha
@@AJRestoration what country are you in?
ive got a G200 Honda and ive got all new parts for it up to the cylinder head, valves, valve springs, crankshaft and associated pieces, etc
хорошо помыл😅😅😅😅
In your opinion A.J., is it mandatory to put the head bolts back exactly where they came from for reassembly?
Small engine rebuilder here. As long as the bolts are all the same length then I don’t think it really matters. They don’t stretch out like on car engines because they’re not torqued no where near as much.
عمل رائع لكن لا يوجد اي شرح او ترجمة او محاثة لما يقوم به لكن لماذا هو صامت حقا امري سئ ان يكون صامت....
❤❤❤
👍🏻👍🏻👍🏻👍🏻
He must think we're idiots to assume that he didn't check his points gap with a gauge
Hahaha I really don't gap it with a guage.
can anyone tell me where the other end of this 39:39 need to be attracted ?
That is the breather pipe, it goes into the air filter assembly. Some engines just have them dangling, like Briggs and Stratton.
It has no compression bc it's leaking out somewhere.
i love your video but, you tube can't send me your notification , so I'm late for viewing this video , 5 days later , do something.
That is strange, youtube has some issues sometimes.
@@AJRestoration when will new video come , I can't wait 🥰🥰 come fast
What did you paint with?
Powdercoating.
