I was starting to mow the grass with my dad's push-mower and I noticed it was smelling bad and it died so I checked the oil and there was smoke coming out of the dipstick hole. For some reason I couldnt get an accurate oil level reading. It was good a couple mows ago.... I really hope I did not just destroy my dads push-mower buy not checking the oil. He just washed it though so mabey he tilted it on the wrong side for too long. I don't know if there is oil in the air filter or not because I dont want to take the stupid bolts out and not be able to get it back on.
