The mower is a 2008 I think. I have compression. I have spark. Pulled the plugs laid them on the engine turned the key to start and I can see spark on both plugs. I have sprayed starter fluid into the intake and get nothing. Can this engine get out of time? I have not tried pulling the plug and spraying starter fluid into the cylinder and then putting the plug back and trying to start it. I would expect that by spraying into the intake port I would get something. A chug, a backfire something to let me know it ignited. Any help would be great.
