Pulled an old Husqvarna mower with a Honda GCV190 engine from the trash to fix up and donate. Looks like it has sat for a while. The photo shows what the float and float chamber look like. They are covered in this thick pasty white goo. Have others seen cases like this? Is the what can happen to fuel when it sits for eons in the float bowl?

It is water damage. Remove all rubber and plastics then using Sulfuric acid (battery strength) soak it until gone. Sulfuric acid will not damage the cast aluminum but a little rough on the steel and tin parts.
Then you need to determine just how bad the pitting is but likely you need a new carb as they fairly cheap right now. Usually this corrosion eats away at the aluminum and look like termite damage.
Being this much damage I would just forget it and order a new carb.
