    Default Toro Zmaster 555 hard to start when cold

    It has a 25hp Kawasaki gas engine, runs great once it starts but starts very hard when cold. Starts fine when hot. I changed plug, that helps a little, but not much. Replaced fuel pump because it had a small leak, that didn't help either. Been this way since I got it new. I use stabil in the gas, run it dry in the winter, stored inside. Any ideas?

    could be the valves need adjusting. I have a kawasaki utv and it wouldnt start when cold but once it was going it started fine. Turned out the valves were in need of adjustment. I adjusted them and problem solved.
