Since this is a diverse and amazingly bright group, I am hoping someone might have an answer for this question. I cannot find a lot on the internet about it.

How do I "dry up" a small engine of gas, so it can sit for long storage?

I have a generator (used only for hurricane emergencies). Per the instructions, I put in a few cups of fresh gas, and ran it till it "ran dry and stopped". But there was still some gas in the tank and I have used a "turkey baster" to get out what I could. It is still "wet" in there with gas, but I am leaving the cap off, hoping it will evaporate (it is a small amount), however, I know there must still be gasoline inside the engine and I worry about that turning to "varnish" over the year or years.

I cannot reach, let alone undo any fuel lines. The whole thing is sealed in a metal housing with insulation and it would take major assembly to even get to the engine itself...even if I knew what to do, once there...which I don't.

So, with the unit still "intact", is there anything I should or can do to safely "dry up" the gas left inside or anything else I can or should do to protect this generator for long term storage?

Any advice or tips are very, very welcome.
