Where are the reed valves on engine?

Reed valves are typically found in two-stroke engines, often located between the intake manifold and the crankcase. They function as one-way valves, allowing the air-fuel mixture to enter the crankcase during the intake stroke while preventing backflow during the compression stroke. In some designs, they are mounted directly on the cylinder or the intake port. Their placement helps optimize engine performance and efficiency by ensuring proper air-fuel flow.
