Replace needles/seats. Problem solved.
You replaced the needles but not the seats. You need to change both. The seats wear also.

Yeah, getting older ain't fer sissies, and forgettin' stuff is part of it unfortunately. Have a cool sticker made that says "PETCOCK" and put it someplace you see it all the time like inside the windshield. My $.02 PAUL B
Will the fuel leak past the rings and contaminate the oil ?
On Benders site or somewhere, I read to use a drill bit with your fingers to smooth out the seat. Also, to use the OLD needle with some valve grinding compound to smooth the seat and then install a new needle.
