Item Name: M12 2.6cc Mini 4 Stroke Gasoline Engine Model Water-cooled Cooling Structure
Cylinder diameter: 13MM.
Material: Brass And Stainless Steel
This is a mini engine with an air-cooled cooling system and a carburetor with adjustable speed. It is made of brass and stainless steel. The bore is 13MM. The stroke is 12MM. Thecarburetor with adjustable speed is used. The ignition is powered by 1.5V power supply and 1/4-32 thread spark plug.
Its starting can be divided into two ways: external force(electric drill)and manual starting.
Engine Startup Steps:
1.Check the wiring of the engine from the board, connect the fuel tankpipeline, and install a No 5 battery(. 5v).
2.Use gasoline(95=)to fill the fuel tank. After the filling is completedturn the flywheel clockwise on the right side of the engine(power switchsurface) for many turns. No air can be generated.
3.Turn on the power switch and quickly rotate the flywheel clockwise onthe right side of the engine(power switch surface)to start the engine.
4. Lubrication method: Lubricating oil of no more than 4ML can be added to the crankcase to ensure splash lubrication of the crankshaft.
5.Fuel and consumption: The fuel tank capacity is about 15ML. The engine can use gasoline and aviation kerosene. The engine needs to add 4% lubricating oil when fueling.
1.If the ignition device is normal and the cylinder compression is normalif the machine cannot start normally, it is very likely that the carburetor oilneedle needs to be adiusted.
2.After tightening the main oil needle on the carburetor, loosen 1/4 turand start the flywheel, so that the mixing ratio of gasoline and air canreach the normal working mixing ratio.
3. When the machine stops, the power switch should be turned off.
4. If the engine has no compression, it should be because foreign matter has entered the engine, which prevents the valve from closing normally.
There are the following methods to try to solve this problem.
a. Put a few drops of lubricant on the carburetor. Rotate the engine for a while, the foreign matter will be discharged under the action of the lubricating oil, and the cylinder pressure will be restored.
b. Rotate the engine for a while, and discharge foreign objects by rotating.
c. Remove the cylinder head. There may be foreign matter on the valve, which will cause the valve to not close properly. So check the foreign matter on the valve and restore the cylinder pressure after cleaning.
d. The valve timing gear may be caused by disorder.
1.Due to the different display and different light, the picture may not reflect the actual color of the item. Thanks for your understanding.
2.Please allow little differs due to manual measurement.
3.Kids should be accompanied by adult.

Just received M12 engine today. Machine IS running well with very low idle speed without any issue.
Here is my cat modeling with this engine.
Nice item, very fast shipping
It arrived in 9 days after I ordered. As it is made of brass and stainless steel, it is heavy despite its small size. I used Coleman's White Gasoline instead of Gasoline because it has less odor and soot and has better startability. As a precaution, I added 5% of Honda 2-stroke oil. I could easily start it with an electric drill with the attached adapter. The throttle stayed slow and the engine ran for about 30 minutes. A good compression was obtained by running around 3 tanks as a break-in operation. It is a very well-made mini OHV engine. By the way, the capacity of both the cooling water hopper and the fuel tank is about 10cc.
i modified this engine in order to set it up on my car. nice engine and nice car:)
I expected this engine to be fun but I was disappointed
This engine is well built and has a lovely finish. I expected it to be fun to change the flywheel to see what effect it has on the engine speed and also fun
to see the small "generator" light up the bulb. Unfortunately the engine did not arrive with the extra flywheel nor was an allen key included, so the flywheel could not be changed. Also the bulb did not light up. When running this engine can only produce about 2.5V, so the 5V bulb is never going to work. A nice example of an alpha type sterling engine, but I cannot rate it more than 3 stars because of the missing items
The engine received was not the one shown on the website
This engine runs fantastic, the problem is that the engine they sent does NOT match the item in the picture. I specifically wanted a thermoacoustic stirling engine with an "extended" hot tube. What they sent was the standard "short" hot tube variety. I already have 3 engines of this style, if I wanted another I could have purchased the one from this site for $23.99 or $19.99. Instead, I paid $29.99. This engine comes with bearings in the flywheel mount so it runs exceptionally fast. It is a great engine overall, but unfortunately not the engine in the sales pictures. Based of performance this engine is "5 star", however Sterlingkit should never substitute engines without customer authorization first
Well I have built this little engine was fun to build took me from 11pm to round 7 am the next morning as I was taking my time going to put it on a stand then start it up just waiting for the stand/base for it
A nicely packed kit love how the box is wood and everything is packed in black foam trays instructions are online but the contents are in plastic box’s. Like screw’s nuts and everything else needed to build it
I sent you an email describing my research and asking to speak with your engineers about reversing the rotation. I have had no response. I am a retired electrical engineer researching chirality and Tesla's concepts on Aether and gravity.
