A four stroke engine contains a lot more rotating parts. Four strokes contain one or more camshafts, cam gears, and a timing chain. All of which cause more rotating resistance (mass) than a two stroke has. A two stroke has none of these rotating parts, therefore, it rotates more easily when kick starting. Also the two stroke fires (sparks) twice as often (per revolution), than a four stroke, doubling your chances of getting spark (ignition) during the kick starting process.

Which supplies more power a 4 stroke engine or 2 stroke engine?
2-stroke engines produce much more power than 4-stroke.
Why does 4-stroke engine has higher RPM than 2-stroke engine?
the 2 stroke has more rpm than 4 stroke because it has less moving parts and the cycles are faster because there is only 2 and in the 4 stroke there is 4
Why you prefer four stroke engine over two stroke engine?
Four stroke engines are quieter than two strokes, but have less power.
Principal of four stroke petrol engine?
4stroke engine are stronger than 2stroke cause you get to break down on a 2 stroke
What is faster between a 2 stroke and a 4 stroke 4 wheeler engine?
i say that a 4 stroke is faster than a 2 stroke
How do 2 stroke engines provide more power than a 4 stroke?
In a 2 stroke, every second stroke of the engine is a power stroke. In a 4 stroke, every 4th stroke of the engine is a power stroke. Knowing this, a 2 stroke has double the power as a 4, in the same cc
Why 2 T engine oil are used in 2 stroke engine and 4 T engine oil in 4 stroke engine?
Because 2t burns cleaner than 4t.
Why do most very small engines operate on 2 stroke?
Most small engines are two stroke because you can get more power from a smaller engine with two stroke rather than a four stroke engine. It takes less to cool and to operate the engine.
What are the disadvantages of a 4-stroke engine?
For a set amount of power, they're heavier, bigger and use more parts than a 2-stroke engine.
Why two stroke engine not used in aircrafts?
In the two stroke petrol engine as you know suction,compression,ignition,expansion and exhaust is completed in only two stroke and one revolution of crank wheel more over diesel ignites at very high pressure which is not the same in case of petrol........if petrol is also ignited under pressure it explodes producing a big thumping sound.called KNOCKINGthis may reduce the power output and also lead to breakdown of the engine. For the above reason two stroke engine cannot compress air and ignite the fuel like diesel engine.
When an engine has a cylinder bore that is larger than its stroke what is this called?
Oversquare
What does it mean by define an engine by its Bore X stroke?
bore is the diameter of the piston and stroke is the length the piston moves in the cylinder.for example if bore x stroke is 1x3 then 1 is the diameter of the piston and 3 is the length of the cylinder.if bore is greater than stroke then it is a short stroke engine.
