Sorry to dig up such an old thread but I am a newbie here and I trying to get my 2000 (aprox.) LTH130 started. My daughter was mowing the lawn with it last year and it ran out of gas and now it will not crank over. I replaced the seat switch and ignition switch and the battery was fine and reads 12.3 right now. I do get a click when I turn the key to on which after reading this I assume is the carb switch because it is coming from the front left. The fuse looked OK so I tore it apart so I could get at the solenoid, which is a four post, and when I crossed terminals it cranked. Should I just replace the solenoid or should I be checking something else first. Any help would be appreciated, I am getting ready to torch this thing.
Since you have a 4 pole solenoid, there will be two smaller wires attached to tabs on solenoid. One will be a ground and the other will be a power wire, test voltage on this wire while trying to normally start. You can also unhook the wire and test also.
