Carburettors don't have timing. A carb will only add a proportional amount of atomised fuel to the air that is drawn into the engine, either "naturally" through the action of the pistons, or forced in by the help of turbos or superchargers.
You can however adust the fuel/air mixture in a carburetor.
Your timing is off in most cases, or your carburetor needs adjusting.

That sounds like your timing is off. Adjust it at the distributor cap with a timing light.
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.
The only fix for broken timing belt or chain is to replace it.
