I was gifted this ATV after it sat for 2 years. After replacing battery and cleaning it up attempted to start it. It shut of immediately after cranking up. Similar to not getting fuel or a bad carb that needs to be replaced or cleaned. So I replaced with a new carb. It has fuel getting to the carb, but still shuts down after about 15-20 seconds of being cranked. Not sure what the next step is... Any advise would be helpful.
