  • DF-15 stalls at high throttle for first hour, fine after that

    My DF15 (2008) stalls intermittantly during the first hour or so of the trip, but only at high throttle, and after it's been running for 15 minutes. A couple times it's been hard to restart, but I think only because I flooded it. It usually restarts with a couple tries. If I travel at a slower speed this usually prevents it from stalling. But then, for the second hour or so it'll run fine, all the way to town, at full speed, without stalling.
    What's going on? At first I thought maybe there was moisture in the tank every time and it burned out after a while, but I wonder if it's something more. I've made sure I'm not sitting on the fuel line. I haven't checked the plugs - they've been in for a year. Would new plugs stop this or is something else going on?
    Thanks.

    Check your spark plugs, see if it is running too rich.

      Hi,
      I have the same problem with my DF15. Have you been able to solve it? What was the cause?
      Kind regards
