I have a TB110 mower that I have had for a while. Was a 1-2 pull started every time. However at one point it started to become problematic. Now, in order to start it I have to turn the entire mower on it's side for a few minutes, put it back down and it will start. I would like to return the mower to it's previous glory but have no idea whats wrong with it or turning on it's side does (don't ask me how I can to that fix) Bought it new, so I am the only owner, store it in garage, change the oil etc....only other maintenance I haven't done lately is sharpen the blade. Trying to figure out what the side thing does that allows it to start when trying the normal way doesn't work.
