NEED HELP! Burnaby power outage

[GoFish]

I did a quick search, there's one on homedepot.com, 7000w for 799us and another on Costco.ca 6000w for 1099.99. Doesn't look like they're nearly as cheap as you can pick up a gas one for but depends on the budget I guess.
Sta-bil lasts for up to 15 months as a fuel conditioner
Every year I start up the weed wacker and outboard engines they run like garbage, always need the carbs cleaned. Have never used a fuel stabilizer though so might be worth a shot if you go gas
