One thing I like about my Stihl MS 170 is that the cowl covering the sparkplug removes by turning a single lock knob 90°. It's like the Stihl folks acknowledged that the thing is prone to flooding, so they made it as easy as possible to pull the plug and crank the excess fuel out of the cylinder.

By contrast, I also have a couple of Husqvarnas, and removing the cowls on them involves unscrewing several screws. They're less prone to flooding than the Stihl, but more trouble when it does happen.
