I got my JD 717 back last Thursday with a new short block and the problem it had is now worse. The problem it had was every day when I cleaned the air filter their was oil in the carb, not a huge amount but enough to notice. After arguing for 2 years the dealer finally agreed to put me on a new short block right before warranty expired. I have had it back a week and checked it today and their was at least a tablespoon of oil in the carb and it was about a pint low. I dont know what else to do except live with this problem or go back to Kohler (which I never had problems with). I will add the engine runs fine with no problems just always had oil in carb since brand new. Any suggestions? Fixer67 or anyone?
