Exactly. I'm "on the wrong side of fifty" and I always do this with my snowblowers. They are 50 and 40 years old, respectively. (I bought both of them used and have had each of them for "only" about 25 years.) One had a gas tank that was full of rust and crud when I got it, and I had to put a replacement tank on it.

Some winters are mild and you might only need to use the blower a few times. No matter. I installed a shut off valve in the fuel line and let it run until stalling out whenever I use it. Then I empty the gas tank fully at the end of the season. With the lawnmower I only empty the tank out when putting it away for the winter. You'll never go wrong in doing that.
