    760 won't start cold

    Hi, 760 won't start cold. Have to dribble some gas into carbs. Then starts right up and is fine for rest of day. Tried choke on, throttle full open and crank for a few seconds(which works on my kawasaki) but no start. Have to dribble the gas. I'm aware of primer kits but want to fix the problem so it works as built. What do I need to replace.

    Thanks.

    Turn the pilot screws out about 1.5 turns from where they are at right now, you will probably have to readjust the idle speed after doing this. Put it in the water and run the ski, if it will idle for over a minute or so and leave without hesitation leave it as is. if it stumbles after idling for a minute turn the screws back in till it leaves correctly, now if everything else in the carbs is correct it should now crank with no choke.
    Y'all know me, still the same O.G. but I been low-key
    hated on by most these &^$$@s with no cheese, no deals and no G's, no wheels and no keys, no boats, no snowmobiles, and no skis, mad at me cause I can finally afford to provide my family with groceries

    I was 300SXing when 300SXing wasn't cool !

    Yamaha's typically start very easily when properly tuned. Try above as WFO states. If you get your screws out too far, IMO you are just band aiding for worn out carbs in need of a rebuild.

    Hard start cold-lean, hard start hot-rich. Tuning dirt bikes teaches you to get the hot start right, cause kicking a hot 450f in a Alabama summer can get dangerous
