I was given a stx38 John Deere(I finally got one) last week but now just got around to playing with it , but I cant get it started. I droped off the carb and cleaned it out,changed the oil filter and gas filter and also the spark plug . If I put gas directly into the carb it will run for a few seconds but no longer than that. Im know Im missing something , so any sugestions on how to get this 12.5 Kohler Command running would be helpful. Thanks for the help By The Way....This mower has been sittig for 3 years, about as long as Ive been cutting the lawn!
