I made a forum search and couldn't find the answer. I have a toro 20007 with a tecumseh lv195ea. I start the mower and then oil starts leaking out of the exaust. I called a dealer and he wouldn't really pinpoint what the problem was but he said something about the carberator. Could it be bad rings or a bad valve? This is the way I was thinking. How can oil get into the cylinder and out the exaust without by passing a valve or rings. Thanks for any imput!
