    The reed valve petals in these motors are very unforgiving and have to be in perfect condition for the motor to run correctly. One reed may be deformed or have a small piece of crud under it not allowing it to close properly. Might want tp pull the reed plate off and hold it up to the light to see how the petals are laying down.
