H74 5cc 4-Stroke 2-Cylinder Water Cooled Gasoline Internal Combustion Engine Model

This is a wonderful piece of art! I bought all three of these engines, one cylinder, two cylinder and four cylinder. And I wasn,t disappointed. They all came with very good packing and in good shape and started running at first try with a wonderful sound. The only thing I was missing was air filters for the carburators so I bought and put those on. Thank you Stirlingkit for a fantastic product.

It's really nice to see how this engine works, it started on the first try. But not only that, it's a small piece of art to decorate a man's office.
I am really very happy with the H74 engine and can only recommend it.
Communication with the Stirlingkit team also works quite well.

This is number two of this kind of engines that I have bought. Same model. I love them. However: I used Zippy lighter fuel on the first one which was a big mistake. After a short time the engine jammed and I had to take it apart. But it would never work again. So a bought another one. Same thing happened again! I had bought a fourcylinder before and same thing happened with that one. So three engines jammed when I used Zippy fuel. However one engine (a two cylinder one) I managed to repair by taking spare parts from the destroyed ones. I skipped the Zippy fuel and used Husqvarna 2% 2 stroke fuel instead. Bingo! Now it works fine although with a bit more smoke. I am so happy now and have ordered a new 4-cylinder engine. So a big warning from me: Don,t use Zippy lighter fuel for these kinds of engines!!! Use 2-stroke fuel.

Very neat little engine I am very pleased with it

Hi, just recived my new H74 engine, it is a wery nice pice of art. I belive you get a lot for your money here !
Details like external waterpump, governor for speed , a pretty radiator with a belt driven fan to see when its rumming.
Just the inntake and exhaust manifolds must be hard to make this small ! And the cool cower for the exhaust like the real tractor engines.
I put some blue glycol coolant in the water to see it better, and filled the radiator, remember to refill after running, as the cylinder and pump space takes some of the coolant also.
Fill gas and start the engine clockwise with the provided start coupling in your drill. Mine started right away and ran nicely, the instructions are a little funny in english chinese, but they do not say if you should fill oil in the crankcase. I filled a little oil upto the bottomof the crankshaft, but rhe engine started making white smoke right away, so I took it out. Maybe oiling the rods and bearings a few drops with a precition oiler are enough between runs.
Wish they made the H74 as a kit to assemble myself, I really enjoyed building the Toyan L400 !
Now I want a small tractor or bulldoser to install this engine in (kit please) I really recomend this engine if you like small mecanical pieses of art that works! Came with exelent tracking information and I followed the package from China to Norway.
