LOOONG story short. Bought a used 48" Leo z-turn for $1000. Guy said it had burned up the starter 4 times, and wanted to get rid of it. Motor had 200hrs on it. I did some research, and found it was the compression relief valve or spring that wasn't relieving the pressure in the cylinder. (19hp B&S ohv Intek plus motor) Took to dealer, created a stink, B&S rep replaced with new motor, I paid $200 for install, and was out. Worked great for a year, burned out another starter, called shop, adjusted valves a little looser? and put another starter on. Worked for another year..... I go out today to start it. I get a click from the solenoid? but will not crank at all.....My question is this: I can turn the motor by hand okay. I back up the motor to bdc to give it a little room to crank over tdc, but the starter isn't even bumping at all. I tried tapping on the starter too-no luck. Did I burn up another starter? Where do I start? I'm thinking the valves are tightening up some after a year which is causing some strain on the starter and eventually burning it up every year? I have also had a backfire recently when turning it off (the past 2 months), which would mean the valves could be a little off? ALSO, since they re-installed the new motor, my hour meter no longer works!! How the heck do I fix it? FYI: Motor: 19hp Briggs Intek Plus OHV motor Model-31P877 Type-0121 E1 Code-060206ZE Mower: Bobcat/Ransomes/Textron Leo Model#942280 I would appreciate any input. I REALLY love this mower. The quality is great for what I paid for it, and I would like to resolve my problem. I am willing to do my own valves, etc. I am a little tech oriented, and have at least half a brain to figure some stuff out!! hahah I read a great post from restorob that was quite informative on the valve info! Thanks, in advance, to all/anyone who can help me out!!
