One thing to think about is fuel storage - if it's a gas powered
generator, you need to run the carb and fuel lines dry , put stabilizer
in the gas, and even then you should occasionally swap out the gas.
Since most people don't do this, seldom-run gas generators are unlikely
to start reliably for more than a year or two.
If you really need reliable intermittent generator power, look at nat
gas or propane powered units.
