Usually, I prefer not to dry out a carburetor because the Viton tip on the needle and seat get dry and rigid. They have a hard time resealing or have to be replaced.
I find that running a little 2-cycle fuel mix at the end of the cutting season works very well for all of my mowers.
In the spring, I fill them with non-Ethanol fuel, and they fire right up.
The worst fuel to use in any small engine is the cheapest at the station pumps. If non-Ethanol is not in your area, use the mid-grade with a little Star Tron fuel enzyme additive.
I am not a fan of Stabil in recent years because it has failed me and left a sticky goo in the fuel bowl on several mowers. That stuff also makes fuel shutoff solenoids sticky.
