If I am riding and let off the gas to slow down, the ski will turn off when it gets to 0 mph. I can correct this by blipping the throttle but any idea why this happens? Just picked up this new ski with 83 hrs on it. The double beep on start up it loud sometime and hardly audible at others, odd but seems common? Another thing, when the ski is off for more than 10 minutes , when I start it back up and go to take off it tends to hesiate and sometimes stalls but once it shuts off and I turn it back on, it always accelerates w no problems..thoughts? Previous owner said carbs were cleaned and fuel lines replaced but they are still grey? thanks everyone
