I reason if I am not going to use the generator for an extended period (more than 90 days) I run the bowl dry. If I plan on using it again shortly I don't worry about it. I don't think it will run dry in 30 days. I use this same plan for my outboard motors as well and have not experienced any issues since I started using this strategy about 5 years ago. Adding stabilizer is a good idea but if you pull your gas from the vehicles fuel tank you have to treat the entire tank. I also run the generator every 6 weeks or so anyway so that eliminates the need to drain the bowl and exercises the generator.
