    I found this on iboats, plan to try it:
    "wot drop to idle and it wants to die points towards a loss in crankcase pressure…try this sequence, wot, quick drop to idle, quick snap to 1/2 throttle….if the engine won’t recover and dies this points towards leaking or loss of crankcase pressure in 2 strokes < this assumes the ignition and fuel delivery are ruled out >…causes?…crank seals, crankcase halves seam leaking, worn piston to cylinder tolerances, loss somewhere else."
