Do all 2 stroke outboards have reed valves?

Since a bad reed valve can be the cause of a variety of problems, knowing if you even have these can be useful – not all 2 stroke engines use reed valves. If it just “dumps” into crankcase, like diametrically opposite cylinder, most likely it’s got a reed-valve. …

What do reed valves do in an outboard motor?

Reed valves help push air through a two-stroke engine that mixes with the fuel to create the combustion needed to create power. If the reed valves are cracked, they may not open all the way, which will reduce the amount of oxygen that gets into the engine to mix with the fuel.

What are outboard reed valves?

The reed valves are the one-way door for the fuel/air mix into the crankcase.

Do 4 stroke outboards have Reeds?

There is no need for a reed valve on a 4 stroke cycle engine. On a 2-stroke they are used at the bottom of the crankcase to let stuff in (through the carb) as the piston goes up, and block it as the the piston heads down.

Where does the fuel mix go in a reed valve?

The reed valves are the one-way door for the fuel/air mix into the crankcase. Now trapped and compressed when the piston moves back toward the crankcase, the fuel/air mix travels quickly through the intake ports in the cylinder and piston, re-charging the cylinder for the next compression and power stroke.

What does a leaky reed valve do in an engine?

Leaky reed valvesresult in the engine “rebreathing” the air that has already been mixed with fuel,then regurgitated back out of leaky reedsinto the intake system, and then re-inhaled and mixed with even more fuel. This results in a richer and richer mixture.
