Any fuel leak on the throttle shaft or shut down shaft is caused by a worn
out shaft,worn o-ring or the housing itself.
If the shaft is ok and the o-ring new and still leaking, check the housing
inside were the o-ring sits and you will find the groove worn right into
the material.Sorry,needs a new housing...some part # are still available.
Good luck,let me know how it turns out .
