Cheap carburator or not?

I’ve got a generator(15 years old. Good shape. Briggs engine) gifted to me. It didn’t want to start but I was able to get it started by spraying carb cleaner into the choke tube and it ran alright. Enough to get new gas running through it. I started it acouple times, although it wouldn’t on choke. A month later again no start.

As far as I know the carb needs a good cleaning or replacement. Im comfortable replacing it but disassemble and cleaning is a bit out of my ability and it just seems so dang simple to replace.

Here’s the thing. I see Amazon sells the carb for 15$ with good reviews. Briggs sells theirs for 150$. There must be a massive quality difference but I can’t seem to find a middle ground. Is there that big a difference? Where do y’all source parts?
