None of my CRF engines got the fuel leaking problem ...
The pics didn't show clearly your needle settings ... but apparently you might be running a bit too agressive on slow speed needle setting with which you might need to set the high speed needle on the rich side in order to keep the engine running within a "safe" temperature range.
Suggest you to reset your needle settings (I set the slow speed needle of my CRF engines much richer than yours ... I could see the slow speed needle set screw of my CRF engine from the bird view; I am very agreesive on the high speed needle setting though).
If the leaking problem persists after you reset the needles, Team Orion should get you a replacement front bearing or other parts which caused the leak ...
