For reciprocating engines, the fuel-air mixture is carried from the manifold in to the engine’s cylinders. The Induction System is what provides this fuel-air mixture. It collects outside air, mixes it with fuel, and delivers the mixture to the cylinders where combustion occurs. Outside air enters the Induction System through an intake port in the front of the engine cowling. This air intake normally contains a filter to prevent dust and other debris from entering the mixture. Since the filter r
