Fuel filter for Briggs and Stratton Generator

I picked up a new Briggs and Statton 8000 watt 10000 peak generator and after running the gas out i noticed that there are specks in the bottom of the gas tank. (from production i guess as the gas I put in was clean).

How well of a job does the fuel screen in the petcock on these things do? Will it filter out what I am seeing and I can just clean the screen out when it gums up. I rather not take the tank off and take apart the petcock of a brank new generator to flush the tank.

Also would it be wise to add another inline fuel filter after the petcock? If so what kind would I need? I installed one of those clean plastic with paper on the inside on a snowblower and it would starve the gravity fed carb. This one is also gravity fed and is a pretty large motor (420cc) which one would I need?

 

The screen should catch most everything. The inline filters that briggs uses are also just screens. You can use a regular generic pleated paper filter if you want. If you have one starving your snowblower, it may be too fine of a filter or it is restricted for some reason.
