It might be lean when the choke is fully opened. Leaking vacuum lines can often cause a lean condition.
It's also a possibility that the coil is not performing at full capacity and gets worse as it gets warm.

Why does 1990 MTD ranch king backfire?
If it backfires after you shut it off then it is probably running too rich. Any unburned gas the that is exhausted out and into the muffler will explode with a backfire. With a 1990 model you won't have the anti-backfire solenoid on the bottom of the carb like the newer ones have. If it backfires while it is running it might be out of time. Check the keyway between the crank and flywheel to make sure it is not partially sheared.

Why does a riding lawnmower backfires when you turn it off and how can you stop it?
That is caused by too much gas getting into the engine after the key is turned off. If the mower is new enough to have a anti-backfire solenoid on the bottom of the carb then it must not be working. If it is an older mower and doesn't have one then the carb needs adjusting to back off the amount of gas.
