If it's backfiring after changing plugs and wires you probably cross-connected a couple of the plug wires. You will need to put the plug wires into the right distributor socket. To do that, find the firing order and use a little deductive logic. didn't cross wires, did wires one at the time so not to make that mistake and too noticed just now that the fuel pump does make the hum noise and there is fluid in the tailpipe along with lots of black build-up...

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.
