Honda rancher dies at low speeds and idle

Hello all. A friend recently gave us 2 2003 Honda ranchers. They worked fine for about a day, but then whenever we got below 5 MPH the engine would die. It sounded like it wasn’t getting enough gas. Afterwards it would try to start, but to no avail. When it did the engine would die seconds later. Nothing happens when I hurry and get it moving though. Then about 2 hours later the second one started doing the same. Because it sounded like it wasn’t getting enough gas. I took apart the carborators and cleaned them thoroughly. It didn’t do the trick. Neither the main jet nor the idle jet was clogged. I really don’t know what to do. Sorry if this post was confusing. These are the first atvs I’ve ever owned. Thanks in advance
