iahawkeye83 The old one could be enough, while it might need some servicing it could be within your skillset to do. With any gas appliance the issues are spark, air and fuel, I would suspect it lacks an air filter so you need not worry about that, leaving you with to check the spark, plug, and then carburetor. You have stored it for years, might as well see if it still works and put a bit of effort into it. I need not be pretty, it only has to function.
At those price points (and even well above them) odds are that B&S engine will be made in China, the brand isn’t what it used to be but with a little care they will run for a few years. Note that if it claims to never need an oil change its BS, change it anyways though they will not have provided a drain plug to make your life easier. A top oil extractor (ie goes down the fill hole or dipstick tube) will help with the task. Its marketing fudge, they expect people to destroy their mower every 3-4 years so they buy a new one.
