Hi I just bought a 21" troy built lawn mower about a month ago. I have used it about 3 times. Today when I first started it it started smoking real bad. I let it run for about a minute then I noticed oil under the exhaust muffler maybe an ounce or so. I turned it off and wiped it off and tried to find where it was coming from. Anyway I did not want to do anything to it because it is still under warranty, but I started it up again and there was no more smoking or oil leakage. Have you ever seen this before? Thanks Robert

Yes, If it is still under warranty you should call the company number on the manual and ask if it can be replaced because I work for a lanscaping company and that happened on one of the mowers my friend usesso we sent it back and they found the problem and with the new mower that they sent me tjere was a note that said that one of the workers screwed something up in assembely line.
