Bad Fuel for my other engines. Anybody with suggestions?

[Fluid Power]

More and more I find myself fixing my gasoline powered equipment. It is isolated to small engines. Snow blower, power washer, string trimmer, etc. Engines that don't get used as often as the cars. I have been putting Stabil in everything and it seems to help a little. I just spent 2 hours cleaning the carb on my snow blower that was stored with no fuel and ran empty, (so I thought) There was enough old gas that it varnished in the bowl and when the new gas pumped in, it turned the varnish into a sticky goo that plugged everything! Those things are not really designed to be serviced easily!

Anybody have suggestions?
