Both 2-stroke and 4-stroke engines have a carburetor.
Some two stroke engines have 4 valves, Detroit Diesel 71 series and 53 series engines for example. Most small 2 stroke engines have no "Valves" at all in the sense of the "POP" valve used in four stroke engines. Some people feel these engine has one valve because the piston acts as the valve covering the ports cut into the cylinder walls.
All Riding Lawn Mowers are 4 stroke engines
On a 2 stroke engine, each cylinder fires every time the piston comes up. On a 4 stroke engine, the cylinder only fires every OTHER time the piston comes up. 4 stroke engines have 4 strokes: Intake, compression, power, and exhaust. 2 stroke engines complete these cycles in only two strokes of the piston by use of ports in the cylinder walls. 2 stroke engines usually produce more power for a given weight/size. But, in gasoline engines, 2 stroke engines are typically less efficient (use more gas) and have much higher pollution levels (note: some newer "direct injection" 2 stroke engines do much better on pollution levels than the typical 2 stroke)
they are 4 stroke engines...
They are - most inboard engines are 4-stroke. But as with land vehicles, you can get a smaller engine with 2-stroke (or more horsepower with a smaller engine) so the small engines like some outboards tend to be 2-stroke.

The difference between 2stroke engines and 4-stroke engines are pretty much the same regardless of where the engine is used. To read about it, check out the related question below.
There are plenty of pointers, but quite a few exceptions as well: - 4-stroke engines will have a camshaft, a 2-stroke can do without - a 4-stroke will have an oil sump, and a separate pressurised oil lubrication system. A 2-stroke can get by on oil mixed in with the fuel - 4 stroke will generally rev lower than a 2-stroke - a 4-stroke will generally have intake and exhaust valves in the cylinder head, while a 2-stroke may get away by using ports in the crank case.
All Ford moters are 4 stroke!!
very large is the keyword here. for a very large engines that runs large machines, we need high power engines. two-strike cycle engines produce more power than 4-stroke cycle engines. that's why they are used. as they produce more pollution than 4-strokes, they must be limited to small spaced engines machines or large machines that required very high power.
Most engines are internal combustion 4 stroke (4 cycle) engines.
