I was sick last week and my sweet wife decided to mow the dogs area. When she was done she shut it off by putting the choke on and turning the key the wrong way. Now it is running terrible. Skipping, low rpm and smoking. I have good spark but i replaced the plugs coils and cdi box just bec I had them on hand. It has a new fuel filter and i checked the pickup. Im at a loss. Its a John deere F725 FD590V.
