    I've got a Kawasaki FH430V with only 50 hours on it. Last week it bagan to idle poorly. At low throttle it just won't idle evenly. If I throttle up, it still is un-even, but not as obvious. Up until last week, it ran perfect. What is the most likely problem? Thanks in adavance.

    Try spark plugs, sounds like one is misfiring.
    check your air filter and the cooling fins be sure there is no obstructions.
    if those don't work, drain your gas and see if its contaminated.
    that should give you a start. 1 bad spark plug causes a surging idle.

    most likely problem is water in the fuel tank and carb bowl.
