Concerning contamination to the Stromberg Carb's mixture control area:

I used to have those round, fiber air filters.  One day, after
descending from cruising at 10,500, the engine got so rough I seriously
worrked about making it the last seven miles to my destination airport.

The mechanic I was going to visit, pulled the carb and stripped it down.
We found the fibers from the air filter had plugged up the air channel
and moving-plate-holes for the mixture resulting in a very lean mixture.
It just needed to be cleaned and install a new filter.

The first chance I got, I had it replaced with the foam filter.
