I power washed my lawn mower with it being off. Started it back up and drove it into the shed, the next day I go to start it and its is backfiring terribly, difficult to start but does barely manage to start. It then acts as if it has 1/2 the power it had before, and the blades barely turn. Today I try to start it and all it does it turn the motor over and over and over, with a random LOUD backfire here and there but will not start. I drained all the gas, put in a new fuel filter, and a new spark plug. I poured in a bottle of ISO HEAT water remover too (before draining the old fuel and iso heat additive)... I'm frustrated and the grass now is embarrassingly tall. I have no idea where to start to diagnose this.
there is only 1 spark plug and its a 16hp motor.
