How much water? you might have to get the carby cleaned out as the idle jet may be dirty and clogged.

Not sure my son drove it though a huge puddle and it pulled water into the motor.starts fine in the morn and idles high on chock, till u touch the gas.Then it idles hard and dies.

change air filter and make sure all electrics are dry.

I have its been 2 months now ,replaced the cap and rotor. Sprayed carb cleaner in carb, checked 2 see if the choke was working. It runs great about 1000 rpm,and down the road .
