    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?

    Sounds like a crankcase breather problem,If you had the same problem before, when they shortblocked your engine they reused all external parts and in most cases the crankcase breather also.

    You are probably correct about the crankcase breather problem. Another poster here, fixer67, said something about that when I first posted last year about it. I still dont know what to do to fix it and neither do they.

    It's a little hard for me to remember all the details of all the engines I work on,but if you will post me your model and spec. numbers I will go to my service manuel and see if we can put this problem to rest.

    restrorob, I could not find a number on the engine anywhere, the only number I found was the mower # tco717xo20842. The engine is a 19 kaw. v twin.

    Kaw had a problem with this. The fix was a new style air filter housing. All the thing different was it had a small piece of metal the redirected the crankcase vent gases in to the carb throat to be burned and kept it off the filter. You can fix this your self by cutting a piece of tin and placing it the air filter housing at the point the vent hose from the crankcase breather enters the air filter housing so the vent gases are sucked into the carb and burned off. All engine vent oil fumes and crankcase gases and some times they end up on the are filter if the crankcase breather is does not enter the air cleaner housing right.
