I have a John Deere L130 that every time I start it up it blows enough smoke to run you out of my two car garage, the engine has 50 hours on it, and recently was taken back to the service center for this for the second time. The first time John Deere told the service rep to replace the Head gaskets, which I knew would not fix the problem, now this time they are replacing the engine. The problem I have is that Kohler says that it's because of the angle the engine is mounted on the mower, and not really a problem. Has any of you heard about this issue with the Kohler 23hp engine on the L130? or is this an isolated case, and a new engine would solve the problem?
