GET A SERVICE MANUAL
1. re-jet. The stock jetting is useless. JD jet kit or follow the forum FAQ at the top
2. uncork the exahaust so it will run correctly. Again, FAQ
3. PROPERLY adjust the fuel screw. You put the screw at 1 turn, then turn the idle screw till it barely idles. Then adjust the idle with the fuel screw. If it goes to high, drop it with the idle screw and repeat.
4. Test your accelerator pump for proper squirt. They nozzle clogs very easily. You have to lift up the subframe to see it work.

It's possible your idle screw cable is binding. It happens.
It's also possible that someone 'spec'd' a pilot jet and fuel screw adjustment based on an excessive high idle.
Does the idle drop quickly when you blip the throttle?
