I have a 42 inch Deck Lawn Tractor. It has been in my shed for 2 years without use. I have charged the battery and added some fuel. I got the engine to start but it is running very rough. When I put it away I had run the engine to almost empty but the fuel had been mixed with fuel conditioner. I haven't chaged the oil but when I check there is still plenty of oil in the system. Do I need to allow the system to run out any old fuel in the system or could it be something else.
Run out the old fuel, change the spark plug, oil, air filter. Then fill with fresh fuel...Good luck...Lee
Testimonial: "thanks...all is working great after letting old fuel run out."
