craftsman mower will not crank
Model # 502.255031; engine: 143.436012 (10 HP Tecumseh?). Mower ran fine last weekend. Tried to re-start to put it away and heard a brief "grinding?" noise. Afterward, only hear a "click" when turning ignition key. Have replaced battery. Still only hear a click when trying to start. Starter motor / gears? Perhaps solenoid, but that grinding noise has me worried. If starter motor, need to remove fuel tank for access. However, the oil fill tube appears to require removal first. Does this sound correct? Appreciate any help and will be happy to provide more details. THANKS! And yes, this is an OLD machine.
