Depends on the carb. Sometimes there's an adjustment screw you can turn out, sometimes you need to swap the nozzles(the jets) out for bigger ones.
If the carburetor has an adjustment screw for the lean/richness you can adjust it there. If the air cleaner is dirty or clogged replacing it might take care of the problem. If not, you will probably have to rebuild the carburetor.

Adjusting the carburetor can potentially fix backfiring on an ATV, as backfiring is often caused by an improper air-fuel mixture. If the mixture is too lean or too rich, it can lead to incomplete combustion, resulting in backfires. However, other factors like ignition timing, exhaust leaks, or worn components may also contribute to the issue, so a thorough inspection is recommended. If adjusting the carburetor doesn't resolve the problem, further diagnostics may be necessary.
It will if that's what it needs and it is done right.

How does it run? If it is running rich or lean then the carburetor could be the culprit. If it is original from 1986 I would bet it needs a rebuild.
