My riding mower won't turn over when starting. It is acting like the battery but both Auto Zone and Batteries Plus say it is good. Batteries Plus actually tested it under load. It is not the solenoid, I took a jumper cable direct from battery to starter. It will start if I jump it off a car, or at least it did last fall. So, I think I have it down to either starter or valves need adjustment (compression is too high).
I may try jumping off a car again, that might eliminate the starter. Is there another way to test the starter? I was planning to change the spark plug. If I remove it to eliminate compression and then it does turn over, does that point to a valve problem? I am told the brand/type engine I have is prone to them.
