Our Husqvarna HU800HW is only 3 months old, but sees a lot of activity. Just yesterday while mowing, it doesn't sound right; sounds bogged down. When you start the mower, the exhaust will puff black smoke. I opened the air filter and noticed oil on the filter and in the filter case. As we mulch, we occasionally clog the mower and it stalls. Thus, we turn the mower over on it's side with the air filter facing up.
What could be causing the poor performance? And how did oil find it's way to the air filter??
In addition, what is the part number for the stock air filter? I could not locate it in the Illustrated Parts List for the HU800HW.
Thanks!
