Purpose of Spark Advance Mechanism:  The purpose of Spark Advance mechanism is to assure that under every condition of engine operation ignition takes place at the most favorable instant in time that is most favorable from the stand point of engine power, fuel economy, exhaust dilution.  Fuel System: In a fuel system contains gasoline which is stored in a fuel tank. This fuel   (Gasoline) supply to the carburetor by using pump.   A carburetor which mixes the gasoline with air and fuel lines connecting the area.  Fuel Pump: There are two types of fuel pump a.       Mechanical fuel pump and b.       Electric fuel pump

Advantages of firing order: Advantages of firing order is given bellow i.                    Proper firing order reduce vibration.  ii.                  Maintain engine balancing. iii.               Smooth flow of power is secured.  Ignition turning : It is the process of setting the angle relative to the piston position and angular speed of the crankshaft so that ignition takes place at the end of compression stroke under every condition. Spark Advance Mechanism: There are two types of spark advanced mechanism: i.                    Centrifugal advance. ii.                  Vacuum advance mechanism.
