10 is the gauge of the wire, 2 and 3 are how many leads are in the wire. For instance 10-2 wire is 10 gauge with two leads, 10-3 is 10 gauge with three leads.
Live Wire = usually brown, if not then its grey or black. Neutral Wire = Blue Earth Wire = green and yellow striped
No, it is not ok, it is potentially very dangerous because the two-wire cable has no earth with it. The earth wire is an important safety component that comes with a three-pin plug. An exception can be made for certain low-power appliances that have double insulation. This includes TV sets, radios, and table lights provided the mounting is plastic and not metal. These appliances are commonly sold with a twin-wire cable but often with a three-pin plug on the end of it. The three-pin plug in this case often has a plastic 'earth' pin and it is safe to replace it with a two-pin plug.
You get a two wire plug!! You should never try to skip connecting the ground wire, the soul purpose of the ground is to create safety for you and others around you. the problem is that someone may assume that the ground is part of the wire since the plug is a three wire!! \You will have to skip the ground terminal on the plug. Usually plug has a green screw or wire, ground pin is longer than two other and round in shape.
You don't, in theory, because the ground wire is missing. But if you must, cut the end of and add the new three pin plug, the two flat pins are for the two wires, the round is for the ground that is missing. If something has only two wires,say a light fixture, adding a plug that has the three is useless because the ground wire is missing, so it does not become safer just because you added it. If the end is bad,then you get a plug end that comes apart and is made for adding to a wire, do not cut wire,add another plug end by splicing it together with electric tape.
it is the brown wire in a three pin plug
I need a lot more information. I don't know what you mean by four wire plug. What does it look like, what was it used for? What three wire plug are you installing, what does it look like, what is it used for. What color ore the wires?
it gives you an electric shock
There is no specific order that you have to follow to replace the spark plug wires. My advice is to replace each wire one at a time in order to not get confused which is easy to do. Just remove one wire, get a new wire the same length and replace that wire. Then move to the next wire.
If it is the same plug every time, I would say the plug or wire is grounding out some where. Try replacing the plug the the wire.

The green wire is for ground. You can attach that to any metal part of the frame. The red is the active and coincides with the lefthand prong into the plug and the black in this case should be the Neutral and ciocides with the right prong into the plug as seen standing behind the plug.
The magneto armature is attached to the crankcase next to the flywheel. It can be located by following the spark plug wire. This leads directly from the spark plug to the magneto.

If you put the spark plug leads back on in the wrong order the engine will most certainly miss fire. The best way is to find the number one spark plug wire and then follow clockwise the firing sequence for the engine.

You need to start by checking to make sure that you have to right wires. Make sure that you tak one wire of at a time so that you don't lose the firing order. Take the new plug wire and match it up with the old plug wire of the same length. and plug it in. Finish the other three and you got it.
