It really should not have any problems at all, if you have not put oil
or gas in it yet. As long as it is stored in a dry area you won't have any
rust issues. I too have a genny that we bought 2 years ago, the first year
it saw no use at all and I have only needed it for 8 hours this past summer.
Since I have gas and oil in it I run it for ten min. once a month and use
the fuel shut off and let the carb run dry. I use Stabil in the gas tank but
this summer I will drain the tank and use that gas in my mower. Having an
emergency genny is an iffy proposition, its there when you need but its also
sitting there wasting money if you don't need it. We had an outage of about
8 hours last summer, we had the genny running our fridge, A/C and sat TV and
lights. Luckily, we did have the genny because our neighbor has a health
issue that requires an O2 generator. They do have a battery backup but that
only lasts 3 hours, I was glad that we were able to help. Thats when the
genny paid for itself!
