A 1985 Honda FourTrax may start and then backfire when given gas due to several potential issues. Common causes include a clogged fuel filter, dirty carburetor jets, or an improperly adjusted carburetor that leads to an incorrect air-fuel mixture. Additionally, ignition system problems, such as faulty spark plugs or ignition timing, could also contribute to these symptoms. It's essential to inspect the fuel system, carburetor, and ignition components for issues to diagnose the problem accurately.
