I've heard that you should use up all of the gas in the tank before
it's stored for the winter but I watched this Youtube video and the
guy says Briggs and Stratton recommends to fill the tank before
storage. What is the CW on this?

Here's the Briggs and Stratton site which says to only do so if you
use their special additive.

My normal technique is to shut off the fuel valve and run the carb dry,
while keeping the tank full with gas and Sta-Bil. I don't generally have
any problems. I think keeping the tank full with stabilized fuel helps
prevent rust in the tank if it's a metal tank, obviously not a factor
for a plastic one. Running the carb dry keeps gunk from forming as the
gas slowly evaporates.
