 In California the dust on the dirt strips can linger in the air long
after a take off and when the farmers work the fields near by, the air
is full of highly abrasive dust. One of the first things we noticed
about Indiana when we moved from CA was how much less dust was in the
air.    I don't know if the Rotary is more tolerant  of this stuff
than is a recip but it probably is harmful to some degree.  Even in
Indiana I think a filter is a good idea.    Jerry  =20

Velocity, so hopefully no hard chunks are ever going to get in there;
but the screen will insure nothing very large. =A0The screen is from a
