About a year ago....but I have been gone for a while and it has set. It has new MSD wires, rotor, plugs, and was running pretty good before I left. But it has sat for about 6-8 months without running. Seems the battery won't hold the charge after it has been started and I have to feather the pedal to keep it from dying in park. It dies and won't turn over, like the battery is dead....
