Yes, that is the problem as JoeAirport has outlined, but it is greatly reduced or enhanced by the low end tuning. If leaned out correctly there will be no pooling of fuel. The petroleum break in oil tends to be stickier on the reeds as well and so going to sythetic and leaning completely eliminates the problem.

It appears DA has already modified the carb block on this engine so leaning is the only way to fix the problem
