Looking for some mower maintenance and where to get parts if needed. I have a Toro self propelled 6.5 HP recycler and it's 3 years old. I mow my yard only and it's been working fine until today. I'm mowing away and then huge billows of white smoke start kicking out. I put a new plug and filter in two months. I pulled the plug and filter and the filter is dripping oil and the plug is wet. I pull on the starting cord and fluid is coming in on the plug side. So, obviously I have a bad ring or plug. What's my next step? The manual supplied is only for standard stuff and nothing this detailed. Do I need to pull the head and get a new ring or what? The unit is only 2 - 3 years old so I'm wondering if there is a warranty but I bet it's done with by now. Any help on diagnosing the problem or a good on-line parts store would be much appreciated.
