/ @ajrestoration 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.

Oh man.... Leaving us waiting in the assembly phase is the worst!!!
I wanna see it gooooo!!!!! 😁
Me too haha, sorry about that, time caught up with me and these little engine restorations do take up alot of time to restore.
Well, you asked if that piston looked burned. I do not think so. Not sure what the color is all about, but I noticed that where the piston actually touched the walls, on the two sides that feel the crank pressure it was clean metal. So I don't think it was heat as the burning would have been on the sides that were clean not on the whole side where the piston pin sits. And it is not centered on the piston pin, it is all the way down the skirt. The exhaust valve, most certainly toasted. I would try my best to replace that as it looks to have gotten hot enough to have lost all of it's heat treating and is now "soft" compared to spec.
The yellow color on the inner part of the crankcase looks like a film I have seen develop when oil and water got mixed, and ran for a long period of time, and baked on some kind of residual salt like calcium carbonate and a little iron that was in the contaminating water.
All the caked on dirt out of the various outside parts was likely also all caked into the cooling fins which may have been the reason it got hot. I am guessing the previous owner tried with an air compressor to blow out the dirt on the fins, and get it running again, but with that burned valve, it was a lost cause. I noticed the same dirt on the fins, but like they had attempted to do a blow out to see if it would help.
Great video, thanks for sharing!

Restoring is environmentally friendly.👍🏻🙂 This engine appears to have driven a water pump that pumped water with mud in it.
That honda engine.is in the right hand s your,s you will get it back in running condition I know you can
Yellow color. Some kind of additive, perhaps.
That engine was roasted hope everything like the block and crank are still in spec. If I ever make it to South Africa remind me not to drink your coffee it's a little thick for me LOL !
Hahaha real men drink coffee straight out of their engines! I ll get it running again, even if its for 30 glorious minutes.
That yellow colour, and the lacquer on the piston- looks like stale petrol residue?
That is possibly the case yes.
👍👍
Great job again so far 👍 looking forward to seeing part 2, like I said before I haven't got a clue about engines but I really enjoy watching you restore them.
Thank you so much!! You should try to restore your own little engine some time, its great fun!
Зачем растягивать ролик на несколько частей????
th-cam.com/video/otY477D2JEQ/w-d-xo.html compression ring on the fuel tank??? wtf? ;)
Saya mau beli ringnya aja tp susah nyarinya lur di lajada gak ktmu
Brilliant. A genunine restoration - none of that weird orange fake rust YT is inundated with. Thumbs up!
I have seen those fake rust videos and its dead obvious!
Them sticking valves are annoying. Looks like varnish on the valve stem. Carby cleaner will fix that.
When you said No compression I thought oh no this is got to be bad. Few, just a sticky valve. Cleaned up nicely, great job. Waiting for part 2 now
That was exactly my thought! I was really worried!

Good video 📹
Sperartnya beli di mana bos .. type mesin GX150
André. Daai oranje kleur kan wees dat die mense verkeerde olie ingegooi het. Baie snaaks maar kon ATF olie gewees het.😂😂😂
Geez imagine dit was ATF olie, Dan het ek baie respek vir Honda nou. Arme ding haha
@@AJRestoration jaa neh haha😂😂
I'm pretty confident that yellowish orange is from an oil additives kinda like a special signature. Penzoil was known from advertising that a protective coating would aid engine health. Hence the hue
This little engine has been cooked within an inch of it's life and if I was to take a guess it's been around a lot of water and condensation has got in too.
It would help if you could put the type fluid in ,the cleaning fluids please 🙄
wonderful, I am enjoying watching these engine fixings.
Great episode! Looking forward to the next one! Keep it up, dude! 🍻🤘💜
Good job🙏
Thank you 🙌
You should have inserted "Subscribe" sign at 22:21, when parts go "Ding-dong!" =)
Nooooo hahahahaha I missed a great opportunity!!!!
Valeu AJ! aguardo ansiosamente a continuação dessa restauração. Abraço
oh boy someone cooked that engin
Now that was good coffee hahaha. Also i love the fact you use Petrol as a degreaser…it really is the best out there LOL. Can’t wait to see part 2 now :)
Ill send you some of this coffee haha. I hope I can get it to work again, its pretty busted up.
Hola bro
Looking good so far. Look forward to part 2!
Do you get inspiration from Machinery Restorer?
I do kinda yes, its a mixture between him and Mustie1. And its fun.
Wonder if the orange color was purposely done at the factory?
I think so too, it is the first time I saw that orange color. I have another Honda G150. Ill take it apart and see if its the same.
Good job mister
love the videos but one piece of constructive critisism.... you should include more of the repairs you do like the obviously dented gas tank( looked great BTW) and less of the powder coating scenes. your very thorough but would like to see all of your processes instead of just the same ones video to video
Thanks for the tips! the tank was replaced, I did not remove any dents, I usually make more dents than remove them.
@@AJRestoration that is fair and honest. like other commentors said, at least you are being true and not just serving us Fake Rust Daewoo F1 engines!!!!!!
