What happens when a reed valve goes bad?

Cracked reed valve petals may not open all the way, preventing oxygen from entering the engine to mix with the fuel. ... Difficulty with acceleration – Failing reed valve petals can cause the engine not to immediately respond when giving it more fuel and then lurch forward when the fuel is finally ignited.

How often should reed valves be replaced?

Always check the instruction manual for your engine before and during assembly. Generally, reed valve petals should be replaced every 100-150 hours.

Can a bad reed valve cause low compression?

Will a bad reed valve cause low compression? - Quora. NO, the reed valve, in 2-cycle engines, does not effect compression in the cylinder. It will, however effect the pumping action in the crankcase. The fuel/air charge will not be effectively drawn in and compressed in the crankcase if the reed valve is malfunctioning ...

Will bad reeds cause no start?

Depending on how badly bent the reeds are, they can make the bike extremely difficult to start.

Should reed valves have a gap?

The petals should be seated against the cage with roughly . 015-inch air gap between the frontal edge of the petal and surface of the reed cage. The tolerance for air gap varies slightly by manufacturer, and also varies per each model.

How do I know if my snowmobile Reed is bad?

When visually inspecting the petals, look for chipped areas or cracking, especially in the corners of the petals. The material might start to flake off, too. Petals should be seated tightly against the cage, but to test, lift them with a fingernail and release them. They should make a firm 'snap' noise when released.

What does a reed block do?

The block fits between the carburetor and the engine. With a lower pressure zone on the engine side, the reed petals flex open to allow fuel/air to pass, when the lower pressure switches to the intake tract side, the reed petals are forced tight against the reed block to seal off the intake tract.

What are engine reeds?

Reed valves are commonly used in high-performance versions of the two-stroke engine, where they control the fuel-air mixture admitted to the cylinder. As the piston rises in the cylinder a vacuum is created in the crankcase beneath the piston.

What is a reed valve and explain its function?

The reed valve function is to regulate the fresh gas intake in the crankcase and/or combustion chamber of a 2 stroke engine. The reed valve is therefore a key component for the bike's performance: the fuel supply of a 2 stroke engine gives in fact the power and torque's output values.

Do 4 stroke engines have reed valves?

A reed valve is used on 2-stroke engines. In a 4-stroke engine the inlet and exhaust valving is done with poppet valves that are opened by the camshaft and closed by a spring. There is no need for a reed valve on a 4 stroke cycle engine.
