John Deere L111 Mower with B & S 20 HP V twin engine, Model 406577 Type 013?
John Deere L111 Mower with B & S 20 HP V twin engine, Model 406577 Type 0139 runs fine when started cold, then coughs and quits after 15 minutes or so. Have already changed oil, spark plugs, gas, fuel filter, air filter and fuel pump. What next?
