Well, I have a big question to ask you all. I hope I can get some help. A neighbor friend of mine wife comes knocking on my door and is upset that her daughter had added antifreeze to the fuel tank on there grass pushing mower and it would not start again. Well, I went down there and we first drained the fuel tank out to remove the antifreeze that had been put in there, then we added gas and still could not start the grass cutting push mower, then we drained the gas out of it and added fresh gasoline back into the tank and kept cranking with no luck at all. Then I took the carb off and blew it out really good and put it back on and still did not crank. We even had blisters form on our hands from cranking it soo much. What else do I need to do to get this grass cutting mower to start again? This mower is about three years old and is pretty new still. I need help to helping my neighbor get there grass cutting mower started and working again. Thank you, Bob
