I have 10 hours on my 7320 athe joystick starts to stick when it gets warm. Its strange because it doesn't stick everytime. I know pushing down it will stick in float. Any ideas?
Does it only stick pushing down? There is a detent that if you push all the way will hold it in float. Not sure if that is what you are seeing or not. That would be normal.
Not familiar with 7320. Does it use cables to control spool valve or is the joystick mounted on the valve? If cables, I would start there to make sure they are not binding. Then I would take valve apart to clean and inspect.
