Thanks everyone for all of the informative comments.
The only thing I know for sure is that fuel filters do their job. The filter didn't let anything into the carbs. I bought two (2) new filters, one to install and the extra goes in the glove box. And, by the way, they come with a rubber gasket in the box if the one you buy is a WIX #33034. No more cork!
Thanks again!
Joe
