Oil leak or overflow?

[RWilson2526]

I decarbed my engine last week out on the lake....used seafoam in a portable tank with 3/4 gallon of gas.....went through the procedure and afterwards ran WOT for at least a half hour or so around the lake. noticed afterwards at home when I took the engine cowl off to change the plugs about 1/4 cup or so of clean 2 stroke oil pooled in the bottom of the engine housing towards the front as the engine was tilted up. Couldnt find any signs of the point of origin of this oil from the resevoir or anywhere else. Everything looked clean, traced the line from the resevoir and all seemed ok.

Anything to be concerned about?
