Hello,
I have a nearly new Husqvarna Z554 w/ a FX751v Kawasaki engine. The mower has 65 hours on it. Last year at 32 hours it started choking down bad when starting off mowing up an approx. 5-7deg incline. It sounded like it was starved for fuel but not sure. I can pull back on the handle to stop it and it catches up and goes on. I changed the fuel filter and it went away. At 64 hours it did the same thing. I put a new Kawasaki fuel filter on it w/ no improvement. I then bought a higher fuel flow Kawasaki filter and put it on just a "shot in the dark". Same problem. I called Husqvarna and held on for over 12 hours over a few days and never did reach anyone. The dealership's "mechanic" doesn't have a clue. It doesn't have the problem on level ground or going down a grade. I use 90 octane ethanol-free fuel. None of the fuel lines are pinched or kinked. Does anyone have any suggestions? Thank you
