Kubota knock off, what a surprise! How do the Chinese get away with stealing/reverse engineering other peoples intellectual property? If I were to do that here I would very quickly find myself in court facing huge damages for breach of copyright and infringement of patent.

That said I own several machines with Chinese Honda copy engines and most of them perform well enough but I doubt there longevity.

So give it a bit of love and attention and it should last for years.

Thanks guys.  Good info.

I've put a lot of thought into the IP theft by Chinese companies.  It seems to be absolutely endemic to their nature to take without asking and claiming IP as their own.  This will need to be addressed before they can be taken seriously a true global power.

All those sticky political issues aside, does anyone know which particular model of Kubota they knocked off with this design?  Also, why would they have chosen this particular Kubota design vs. any other diesel design within this HP capability?

Granted, I've just discovered the world of large single-cylinder diesels, but I think I'm beginning to get a grip on how they got here.  The Chinese singles (Changfa/Changchai/Laidong/et al) seem to be knockoffs or were at least heavily influenced by an old Yanmar walking tractor design.  They seem to have been originally created for use on said walking tractors, hence the otherwise inexplicable headlight commonly found on them.

Yet I've seen so many claims that they are actually a German design.  Would that be a German design specifically created for the Chinese makers, or would it be a patent-violating copy of a proven successful design?

And this leads me to another entire line of thought:  How did the Chinese choose which engines to copy?  Was it based on manufacturing ease, manufacturing cost, durability relative to cost, or fuel efficiency?  Is there a list somewhere of the "donor" engines which the knockoffs are based on?  For example, the 195 or 1115 design - is there a direct western or Japanese equivalent which was simply copied?

So many questions.  It really does fascinate me to try and figure this stuff out.

Also as far as the rust removal from the water jacket goes, I'm first going to try an EvapoRust product called Thermocure.  It's designed to do exactly what we're talking about, and for $16 I'll give it a shot.  If I'm not satisfied with the result I'll up the ante and try some harsher chemistry.

Couldn`t agree more, I had a Victa 2 stroke lawnmower, got it second hand six years old. scraped it this year because the chassis had rusted out. Engine probably still had ten years left in it. That said, it drank fuel and two stroke oil. I replaced it last year with a top of the range modern Victa mower with a Briggs and Stratton engine. Nothing but trouble, carburettor off it weekly cos it won`t start . It`s also developed a nasty vibration which I think is probably the lower main bearing, I`ll know for sure when the bottom oil seal fails and spits sh!T everywhere.

I am a big believer in the idea that you get what you pay for, Chinese is as good as any product, if you want to compete with them you need to find a way of producing a better quality product at the same price.

The alternative is to buy old, quality machinery, restore it and enjoy problem free use for the rest of your life, which I think is the whole purpose of forums like this.

Well I tried hard not to get into political nuance.  It's a topic which influences our current discussion, however.

Glort, you're very well informed about the history of diesels and other small engines.  Thanks for your input on that.  But please don't assume everyone from the U.S. is completely naive about global politics and how things work.  I've been to every continent save Antarctica, at last count 25 countries, and have personally been to China to do product and factory inspections when we were thinking about importing and selling evacuated tube solar water heaters.  To be told I need to open my eyes to the nuances of politics comes across as being a bit off key.  And I also have no idea where you got the idea that I think Yanmar is Chinese.  I never said or even implied that to be the case, and I already own one of their tractors.  Also a Kubota and a Mahindra.  Yes, I also know the Mahindra is Indian, not Japanese or Chinese.

Also, the reason I'm here on this forum with you guys in the first place is that this is an exceptional repository of knowledge by some fine folks who live and breathe internal combustion.  Twice now I've been told to "Google it" as if I haven't put in the homework before asking questions.  Yes, I could do all this on my own.  And usually I do it all by myself.  But what fun is that?  How would I get the viewpoints of others who already have been steeped in the lore for decades?  How would I learn about the questions I don't even know to ask?  And also by asking the seemingly simple questions and having them answered here, they're saved for posterity.  And I think you all can admit that it's at least a little bit fun to be able to show off your hard-won knowledge to the newbie and to each other.

To outsource the search for knowledge completely to Google while ignoring the people's knowledge is going to be one of the downfalls of civilization.  The Lore should be kept alive from person to person, not outsourced to our Silicon Valley overlords.

It's no great surprise that China is copying other peoples designs after all they make them for us! The Chinese engines on stuff like pressure washers and generators are good because they have the blueprints and specs. I mentioned earlier there's a company selling generators with 186F engines but they're made under license in China under license from Yanmar. My Korean brand TV was made in China as was my Finnish brand phone and Italian brand coffee machine. To be honest they are good enough products the big companies are interested in the bottom line if they could train monkeys to make stuff they would.

Just wondering, if I found a product that was invented, designed and produced in China would I get away with making rip offs in Ireland and selling them in Beijing? I think not,  most if not all of the western world is up to their tits in debt to the Chinese .  I doubt anyone really wants the Chinese to call in the debts

Knew an industrialist when I lived in the UK, b*stard claimed to be a socialist and even ran in the local elections. Laid off all his 400 workers and shut the factory so he could transfer production to China. More profit in importing goods than manufacturing and exporting them. No wonder we are all in debt to China when our own industry is run by greedy, selfish twats like him.

I never run E10 in any home engines, as you say it is hydroscopic and causes too many problems. The problem with the Briggs and Stratton lawnmower is that there is no fuel filter, just a strainer in the fuel tank. Main jet keeps clogging with bits  of grass. One day I`ll get around to fitting an in line fuel filter. That`s if the bottom bearing doesn`t fail first.

We don't get E10 in Ireland or rather we do but we don't really have a choice it's in our unleaded petrol. I use fuel stabilizer in the lawnmower, pressure washer and the 2 stroke generator. I don't know if it does any good but it does add a fiver on to a tenners worth of petrol. Most used things I buy with a small petrol engine usually needs the carburettor cleaned or replaced (very good Chinese copies for 12.00)!
We used to have 4 star pumps in Ireland they seem to have went the way of Park Drive cigarettes and scantily clad ladies on lager cans. I occasionally see 4 star pumps in northern Ireland so I assume 4 star is still available in the UK?

Aaah... There should be a word for "The feeling you get when house guests finally go home."

Today I had some moments for myself for the first time in nearly a week.  The generator was unloaded much easier than it was loaded thanks to the Kubota M7040 and pallet forks.  I hacked a diesel line together, attached the battery, and it fired right up.  Whew!

Here's a few more shots of the engine data plate, which I couldn't see in the darkness of the garage before I picked it up and was too tired to find after the loading.  I love engine data plates.  So satisfying.

If I could only get ethanol laced fuel, I'd wash it.

Pour water in it, shake it up and let it separate.  The Ethanol will go into the water and form a layer and the clean petrol will be underneath. Drain water off from bottom of drum and clean Petrol left.

Yep, Done it numerous times and it does work.

No, no water in the petrol because pure petrol and water wont mix at all. 

Also have a look at the MSDS of your Fuel stabiliser.  Naptha ( lighter fluid, shellite, Coleman fuel and other names it's sold under) is a VERY common additive to all Oil and fuel miracles in a can. If that's the main ingredient in your fuel treatment, You can probably buy it for 1/10th the price by volume from your hardware or paint supplies store.

MANY additives for fuel and Oil treatments have this in them ( no matter what they are supposed to do) so if it's in the stabliser as well, there is a much cheaper alternative to getting a better result than the packaged additives that usually just have naptha and something like Diesel and kero in them.

Thanks Glort. From what I have been reading its pretty similar to Zippo lighter fluid, turpentine and refined lamp oil? I assume some of the other ingredients are like the secret ingredients in grandmas soup/sauce/cake etc?

"Distillates Hydrotreated Light"   No idea what that was so I looked it up....

Naptha!

:laugh:

It's a bad day when I don't learn something!

The only thing I learn every day is how little I know, a life time of studying and learning and you guys still leave me baffled.
Well done with firing up the Chinese monster, hope she runs well and gives good service.

I have seen videos of Glort throwing oil into an extremely hot incinerator and I thought "you mad bugger" I read his posts and concluded the mans a genuine pointy head, big brain, smart man who happens to be very good with his hands (the amount of smart people that have no practical skills is amazing" I pay 5.00 for 100ml of fuel stabilizer, thanks to Glort I can now buy 750ml of mineral spirits for  2.00.  Thanks mate!

Any chance to get a link to the video, John?  Sounds like high quality entertainment to me.
