I bought a used Husqvarna mower in August with a 22hp twin cylinder b&s engine and she's a smoker. My lot is about an acre and I have to add a quart of oil after 2 mowings. Then I have to take a shower since I smell so badly from exhaust fumes. Motor runs good, and I'm sure it needs rings. But I'm wondering if there's any "snake oil" treatment I might add to get me through the season. This will most likely be my last season of mowing lawn myself as I'm 78 years old. I'll hire someone next year. Just want to get through this season. Any ideas?
