Default RE: Reed valve on RCGF 20cc engine

If I understand this correctly, the reed valve spacer will be placed against the motor and the reed and its retaining screw will be on the outside. I don't really understand how reed valves operate and I thought the reed would be on the inside next to the crankcase so it would open to the inside of the motor. If I mount it as my opening statement, the reed will be outside against the back of the spacer and I wasn't sure it could operate that way. I thought it would have to flex inward to allow the fuel charge to enter from the engine vac.
