I have a 1968 Johnson Airbuoy. It is a hookah dive compressor attached to a Lawnboy lawnmower engine. The unit was sold by Johnson in the 60's. Parts for the engine are available through lawnboy very easily. However, parts for the compressor are another story. One of the reeds in the compressor manifold just broke and I have no idea where to get a replacement reed. Can anyone out there help me at all?
