After using a lawn tractors slightly oiled, green foam filter on my
experimental with C-85, a fellow remarked that it was much too thick
(about
1") as I replaced it.

Just wondering what non-certified (read cheap G) alternatives that
others
are using. Seems like most guys use a pleated paper-like filter...

Thanks Dick

A Brackett filter for a certified aircraft with C-85 would be about
the same thickness. You don't want to suck anything, such as a part
of the filter, up into the carburetor.

Even Bracketts have had their problems with AD's because of parts of
the filter migrating into the venturi.
