White smoke and spitting oil?
I shouldn't be allowed to operate power tools anymore, but whatever... I was mowing my yard when I hit a piece of hidden wood. A piece of wood jammed against the side of the lawnmower and the blade, which required me to flip it on its side and dislodge the chunk of wood. After I removed the wood, I put the mower back into its right position and took a break (It's hot out..). After my 45-minute break, I went to start it to finish cutting and it was belching out white smoke, and leaking and spitting oil out of the muffler. My father and I took a look at it finding nothing, but I took off the air filter cover and there was also an oily residue in there, more than normal. What could be wrong with it?
P.S: Comment if you want pictures.
Is this a good question?
