Thanks to all for comments on solving the Onan kicking up dust. I will
call Alex for the deflector. This episode will encourage upgrading the
Onan to electronic ignition.
Thanks to everyone on the net for all of the great information. I am
updating a 78 Royale and all of you have provided greatl information. I
just wish I had the time and the $$$$ to do them all.
