Well the answer is still NO. The propeller that comes with the Break-In Bench puts a load on the engine that prevents it from going on to the high revs that the engine could reach, plus the rich mixture setting adds to not allowing high revin. Properly set the engine reaches the right revs for WOT Break-in.
You have to set the HSN for the engine to be rich in 2 stroke and at the right temperature of around 90°C.
