    Why Is My Polaris So Hard To Start?

    I have a 1996 Polaris 700 SL that takes forever to start if it has not been used for a few days. When it does start it runs great. Any ideas?

    Welcome to the Hulk!

    Click here for Polaris service manuals, and other useful info.

    I will presume the battery is strong, and is delivering over 10.5 volts while cranking the engine (measured with a multi-meter). If it isn't, replace the battery.

    Have you confirmed that you have a strong blue spark during the first few seconds of cranking?

    If you still have the original gray Tempo fuel lines, then you should replace them, and clean/rebuild the carbs. This is a precautionary thing, to avoid carb problems that can cause engine damage.

    If you have spark, and battery voltage is healthy during cranking, then the area to focus on is the fuel system. If any of the hoses or fittings between fuel tank pickup and carbs have air leaks, then the fuel can drain out of the lines while it is sitting, which will then take a long crank time to refill the lines with fuel.

    Air leaks are a problem when the engine is running. Air bubbles in the fuel lines can reduce the fuel delivery volume/pressure to the carbs, and increases the risk of lean burn damage to pistons.

    Welcome to the Hulk Vector.

    Try getting a primer for the carbs. It'll start right up.

    Does anyone make a primer kit for the Polaris skis? I put one on my yami GP1200. Three pumps and vroooom. Away I go. With the choke I would crank for a long time.

    Lots of places sell the primer kit for the Mikuni Super BN 38mm carbs. Usually around $30 for the triple kit.
