"Dear Folks:
This is in Reference to your expensive 250C20 series engines. You are probably aware of the tendency of these engines to leak oil. Much of our maintenance effort is spent on trying to fix these never ending leaks.
I think I may have come upon a remedy for the above problem. For about fifty years I have operated lawn mowers. These mowers have a vertical shaft that drives a blade. This mechanism is immersed in oil. In spite of poor maintenance, sudden stoppage, over speeding (one turned so fast that it almost went into a hover), lack of oil, too much oil, and imbalance and out of track blades, etc. I have yet to see a drop of oil on the surface where the machines were parked. In light of the above I think you should either merge with Briggs & Stratton or hire one of their engineers.
Respectfully,
Bob XXXXXXXXXX
P.S. You might pass this on to MD Helicopters we have the same problem with their gear-boxes. I'm sure they would be grateful."
