Anybody Recognize this? Fuel System Varnishing (algae)

[yamajason]

On my Honda EB2000i Generator, the manual recommends at the end of generator use season to run it out of gas to prevent varnish build up in the float bowl and jets.

If you drain the fuel from the Davco fuel filter housing and leave the lid unscrewed from the top the engine will run out of fuel and die. Maybe it would help. I sure hate the idea of extended cranking on engines without a priming pump or electric lift pump, especially after hearing many higher mileage Detroit engines spin a bearing during fuel priming engine cranking.
