The biggest key is to make sure that you run the gas out of the motor after each use. Most generators have a fuel shut off on the fuel line coming from the tank. Also, if you don't use it for long periods dump the fuel and start it with fresh fuel. Change the fuel filter every year with the annual oil change.
I think you need to change your oil more frequently. I know that Honda and Yamaha inverter generators recommend changing oil every 100hrs.
