Anyone out there who has experience with this? My 1996 800 has been stored by previous owner for 12 years with oil in the motor, gas tank was not drained. Oil was not poured into the cylinders. Previous owner tried to start it 3 years ago and it sputtered but would not run. Wondering if I should pour something in the motor to clean it out or do I just change the oil and go for it? I'm sure the carb will need rebuilding.
