Bran new battery, new starter, new solenoid (4 prong), years ago I bypass my safety seat switch (so its not that).... When I turn my key I get the "oh **** my battery is dead" affect, then click click click... So I jumped it with the car, and thought I will deal with that later. It started right up, threw it in drive, engaged my blades mowed for about half hour and then it just stalled... again I jumped it mowed for a bit and then it stalled repeated a few times more.... now it stalls as soon as I engage the blades. Maybe the valves need adjusting? Maybe a very expensive Armature? It has "over head valves" I haven't located them yet. Most video's online show a valve cover in the front of the engine... I took some bolts off the front thinking it was a cover... it seems to be all one piece. Im confused as where the hell the valves are. I know if I find them I can adjust them, because I saw a video on how to do that. And if that is even the problem, im just not sure. Hence posting here... So what ya think, any ideas?

Hello, I got some excellent help with this same mower in 2007 so I am back again hoping I can get help again. I have a Murray riding lawnmower. Its a 42" cut, shift on the go. Model #: 42819x92A Mfg Date/ Serial #" 94327-027526 14.5 HP On the engine it reads: Type: 022501 Model#: 287707 Code: 9408094A Ok, wanted to get the numbers out first. It just won't start, not even if jumped with the car. There's nothing when you turn the ignition key. No lights either. Battery was charged, was tested good. I replaced the battery cables. Still nothing. Air filter was cleaned, fuse replaced. Oil level good. Nothing again. My neighbor took a wrench and went down where the battery was and said he was "jumping/ bypassing the solenoid". (What ever that means.) It started to turn over slowly, but wouldn't start. I replaced the solenoid. Still nothing. I checked for broken wires but didn't find any. When it was trying to turn over it was slow. Back in 2007 I replaced the flywheel gear and it had worked great after i got help here. I have never replaced the spark plug- can't find its location in the manuals. I have no idea what to check for next or what to do to troubleshoot this problem. I am not financially able to put it in the repair shop. Please give me any advice you can because I am currently using a push mower to cut 2 acres of grass and it takes me several hours to do it. I also need my riding mower to do other yard jobs like cleaning up tree debris. Thank you all so much.
