Problem storting warm DT 140 from 2000

[Johanj]

My DT 140 starts direct when it is cold but refuses to start when it is warm. Anyone who recognizes this problem?

Could be a gear counting coil, magneto coil, or a sensor that may be affected by heat? If heat is causing the values of any of the mentioned above items then that item should be replaced. You should warm up the motor, then check each of those items to see if they are good per the service manual. If one or more of those items is reading bad when warmed up, then it is breaking down when warmed up, replacing the part is needed.

Good luck, post back on what you find out.
