    I think it's a gorgeous engine, I especially love the shrouded radiator and fan, as well as the centrifugal governor. Bit of a bummer that it was a rather shoddy build. Someone not mechanically inclined probably wouldn't have noticed the coolant issue and kept running that thing until the bearing surfaces were completely nuked. I kind of get it, these aren't built on a massive factory line. I imagine there aren't a lot of these built at all, so there are going to be cock-ups. That they used the wrong size o-rings, however, was a pretty big cock-up. Especially as these things aren't exactly cheap. That said, I kind of wish someone could get them to make a submarine diesel. I would be all over it like stink on poo if they did, lol...

    It doesn't control gas (thats controlled with his finger), but it controls the idle. I don't know if real tractor engines have a governor, but it seems resonable a tractor engine must have a governor if you are using the PTO in idle, since putting a load on the engine in the idle will sag it down, thus you cannot have a static idle that a "normal" engine has.

    @@sebastiannielsen Yes, tractors, like most industrial and machinery engines always have a governor. It would be impossiblee to operate a tractor without a governor, not only for the PTO but for normal operation too. Since most jobs are done at very low speeds the inertia is minimal while the load varies constantly and widely, without a governor it would be impossible to maintain a constant speed or even prevent the engine from stalling, the operator would have to be controlling the speed of the engine continuously and that would require a lot of physical and mental effort, distracting the operator from driving and controlling the implements.

    This is a Jianzhong Dong engine, and Jin is an excellent engineer. However, I haven't bought this engine, as it is very expensive and has been problematic with water leaks from the cylinder liners. He is selling improved liners, but should be providing them to previous buyers of this engine for free.

    There is numerous issues with this engine. The worst issue is it’s running backwards. Jin apparently didn’t pay attention when scaling this down from the real H 75. That’s why the fan is turning backwards and the centrifugal water pump doesn’t work unless you flip the belt to reverse its rotation. It really needs a camshaft designed to run the engine the other direction. It’s still a nice engine. I bought mine off of eBay. You can get them on eBay for anywhere from $500 to $700 brand new from Jin.

As a tinkerer, maker, and mechanically minded person, I think it would be super fun to get a big box of parts and put together an engine model like that. I would totally hook up a little generator and a string of LED lights or something just to make it do something and be pretty also. If you ever have any kits you want to get rid of, I'm right over here in Southwest Washington haha.

    Unfortunately you have to flip the water pump belt because it’s a centrifugal water pump and the engine is running backwards! They designed it with the wrong rotation camshaft so the only way to get the water pump to pump water is to flip the belt. The fan on the radiator is also running the wrong direction as it’s blowing air out the front! To correct this they really need to reverse the rotation of the engine and make it like the real one by designing a new camshaft. Unfortunately they used the public as the guinea pigs hence the leaking O-rings and wrong rotation of the engine, water pump and fan!
