This mower will not crank (has a new battery and new ignition switch) I checked the 20 amp fuse,
safety switches for seat, FNR shift, park brake, PTO. I took the starter solenoid
out and checked it. What have I missed??????????????????
What would help would be the model number of the engine. IF this is an overhead valve B&S engine, valve adjustment is a very common cause of this. I can send you detailed Instructions for adjusting them IF you like. Address below, put in proper format and remind me, engine model number and what you want.
Use a small jumper to jump from the terminal on the starter solenoid where the cable from the battery connects to the small terminal IF the starter turns over normally, you will know the problem is in the Safety switch circuit or ignition switch.
