It isn't a necessity to have an advanced fire timing but it can help if you want to run engines at higher ends but you can suffer power at the lower ends. It's important to time your ignition between retard and advance, but it depends on the application you are running the engine on.
Passenger cars should run a little retarded timing or at tdc (top dead center) because the engine can warm up a bit faster if the engine runs retarded. Older cars use something like a vacuum timing system so they can run retarded and the vacuum from the intake manifold can turn the ignition coil slightly advanced to have a better power curve.
Motorcycles should run a bit advanced so they don't run lean at top ends. And since the engine is considered small, they have enough response time to allow advanced timing while having enough low end power.

Can you reverse the spin of a small engine?
Petrol engine? 4-stroke, no. 2-stroke, some.
Is fuel for a two stroke engine fatal to a four stroke engine?
No it isn't fatal, but it would smoke quite a bit, because a two stroke engine needs two stroke oil mixed in the petrol, and a four stroke just needs petrol.
Advantages and disadvantages of four stroke petrol engine?
One advantage of having a four stroke petrol engine is the fuel economy. A disadvantage of the engine is in the cold weather they are harder to start.
What will happen if you put petrol in a 2 stroke engine?
It will overheat the engine
How Air cooling of 4 stroke single cylinder motorbike petrol engine occurs?
The air cooling of a 4 stroke petrol engine takes when the air flows on the engine .it takes not by radiation.
Where 2 stroke diesel and petrol engine used?
two stroke diesel engine is used in cargo ships as cross head type engines, two stroke petrol engines used in two wheelers.
What happens if you put 2 stroke petrol into a 4 stroke engine?
nothing the 2stroke-petrol will smoke as it burns the oil which should be mixed in it
Is 4 stroke fuel normal petrol?
4 stroke fuel is straight petrol, it does not have oil in it! If you use it in a 2 stroke engine you will seize the motor. 2 stroke fuel has oil added to it.
Does a 4 stroke engine use unleaded petrol?
Yes
Disadvantages of six stroke petrol engine?
high cost
Principal of four stroke petrol engine?
4stroke engine are stronger than 2stroke cause you get to break down on a 2 stroke
What happens if petrol mix with engine oil in a 4 stroke engine?
If petrol mixes with engine oil in a 4 stroke engine then the mixture becomes thick and its combustion will not be efficient. The exhaust will be smoky due to this incomplete combustion. also this will reduce engine efficiency.
