  1. Chasing problems.

    ATV is acting choked. Smells of gas. Black spark plug.

    Idles fine. Soon as I hit gas it wants to choke out.

    What I have done:

    1. New fuel pump

    2. Rebuilt carb

    3. New throttle cable

    4. Emptied gas

    5. Checked pit cock

    6. fresh non ethanol fuel

    7. New NGK spark plug

    Did all this and still dogs out when I hit the throttle. Idles fine.

    Its worse when it get warmed up. Wont do hills very well.

    Finally check the compression.

    Cold it was 80 psi

    Warm it was 100 psi

    Book says range between 146 and 199 psi

    Limit says 114 psi

    Range seemed high to me. But I am probably wrong.

    The ATV has had a hard life on the farm. Never did a valve adjustment.

    Always changed the oil.

    Is it time for a rebuild? Any recommendations.

    I would say the ATV is valued at $1000 when running.

    Your thoughts? Thanks. Scott
