TOYAN FS-L400WC DIY KIT 14cc Inline 4 Cylinder Four Stroke Water Cooled Nitro Engine Model Assembly RC Car Boat Ship Airplanes Parts

Important Notice: (Please read it before you start to build this engine)

1. Piston Rings: Our team has assembled the piston rings in the block in advance because it's very difficult to do it for the average people. pls follow the instruction to build it and you will find out the piston is already inside the cylinder liner. they are not missing.

2. Glow Plugs: The glow plugs isn't powered all the time when the engine is running, and they're only powered during engine startup and disconnected battery after the engine has started.

3. Connector: There are 4 carburetors but only one fuel line from the fuel tank so 3 connectors are recommended to make the fuel rail right for the L400. You can choose either T shape or Y shape connector if possible.

4. Battery: TOYAN FS-L400 uses 2s T Plug lithium battery, the same one as that of FS-L200 engine.

5. Fuel: Please use quality guaranteed methanol model engine fuel. Self - dispensing or copy fuel will greatly reduce the performance and life span of the engine. Since it is a four-stroke engine, in order to ensure the normal operate of the engine, we require the only 20-25% nitro methane fuel can be used. If high nitro fuel is used, the ignition time and cylinder pressure of the engine will be greatly affected, and the normal and stable operate cannot be maintained.

When the nitro content of the fuel increases or the brand of fuel change , it is recommended to use oil-rich needle adjustments to run the engine so that the optimal setting for the new fuel can be rechecked, (please adjust the ratio of gasoline fuel to 1:25 to 1:30, and use 2T engine oil).

6. Lubrication: TOYAN FS-L400 has no lubrication system. No need to add oil, just add red grease on the camshaft. The crankshaft and piston connecting rod are lubricated by themselves during operate. The grease will penetrate, and then drain the waste oil from the oil outlet. The crankshaft does not need to be refueled in normal operate, and is lubricated by fuel. When installing parts, moving parts can be mechanically lubricated with two drops of engine oil.

7. Cooling Problem: Try to use non-corrosive liquids, such as water, distilled water, car coolant, computer water coolant and so on. Distilled water is recommended. If not, you can directly use ordinary water, about 180ml.
