Wendy when you do go to buy your generator make a list of some the points listed so far. Like how to drain & refill with oil and how to run the carburetor dry.
Then have them show you at Home Depot or where every you end up buying your generator.
I'm on my 4the lawn mower in 30years. I bought one of the new Electric Mowers with rechargeable battery. Simple plug it in overnight. I have a double lot. I get two full cutting of the whole property per charge and I do part of the vacant lot behind my house that is near my Dog kennel run. (20x100'.)
What I like the best is how quiet the motor is, it sounds like a ceiling fan on high. I can cut the grass at 6am in the summer and not wake up the neighborhood. It's much lighter than the gas mower was too.
