Any 2 stroke experts out there

Ok. If the fuel was leaking past the seat, wouldnt it flood out while idling? I do shut off the fuel after each use because it will leak. It has a bing carburetor and i dont think the float can be adjusted. I will check on these ideas

2 STROKES DO NOT ALWAYS RUN RICH as stated above , they run how they are adjusted/jetted . .
I`d check the reed valve too--------------------------
