This motor is in a l120 John deere mower. When I stored it there was about 1 inch of gas in the tank. I put stabil in the tank and ran it to get the stuff in the lines and the carb. It has not been started in almost a year. What am I going to have to do to start it? I intend to replace the fuel filter, and fuel lines, and change the oil before doing anything. Do you think the motor will be ok? Or what else should I do?
