My brand new Husqvarna AWD lawn mower worked fine, first day out of box, second trip out, the motor is idling REALLY HIGH. How do I turn the idle down?

You may have partially sheared the flywheel key when you hit the rock and this will change the timing.
Good Luck

I don't know what type carb is on this one, but most have a diaphram. If the diaphram is weak it will cause this. You can purchase a new diaphram at a Lawnmower service center. It's not that hard to install.

Float stuck in open position. When the gas evaporated in it there was a gunk left behind and then It was down and either froze up or there is trash keeping the needle valve from sealing up all the way.
So when you start it gas keeps pouring into the motor. It is suposed to shut off once it gets enough to run on.
Be real careful take the carb off and remove the bowl. And then the float. Take a q-tip and clean the needle valve port ou real good. And clean the rubber tip gently. Then put back together.
When it is upside down the float should be parallel with the carb. That would be the shut off point. You may have to adjust it.
That should do it. When you hook the gas line back up loosen the bowl and let gas in carb til it starts to run out. Then mow.
Find a screw touching the linkage on the carb. Turn that screw to speed up the idle.
