My LT133 has been getting increasingly hard to start, and it has passed beyond the 'annoyance' stage. The issue is that I turn the ignition key and hear the solenoid click, but the starter motor doesn't kick in. Sort of like a low battery, except there's no reaction at all from the starter. If I keep bumping the key, the starter will *eventually* kick in with cranking power. (so it's not a low battery. It's been doing this all season, but at first it only took a few tries for it to start. Lately, I may have to bump the key 40 or 50 times before it catches.
I disconnected the cable between the solenoid and starter, and cleaned the connections. They weren't bad, but I brightened them up anyway. No improvement. My guess is that the starter must be dying, but before replacing it, I'm asking for advice. Is there any other thing I should check? Is there a way I can verify that it's the starter? Thanks for any suggestions.
