John Deere cranks nicely but won't start.
Well maintained 1985 Deere 112l riding lawn tractor. 440 hours. Always starts. Changed oil filter, air filter, spark plug, greased, replaced fuel line all about three Months ago. Yesterday while engaging the pto switch with deck down, it conked out. It cranks really well but wont start. Icleaned the carburetor, charged battery, cleaned the plug, checked air filter(both were clean) and nothing.
When the problem started, engaging the PTO resulted in one of the lifter arms popping off. That's when I couldn't get it restarted. I was able to snap the deck lifter arm back in place and greased them, and raising and lowering the deck is smooth now. Any ideas. I am thinking the PTO switch has something to do with it, but don't know the next step. Thanks
