Hard to start, found problem. Now Why?

Thanks for input AJ/FormS. All timing was done w VacAdvance disconnected and set to maximize vacuum from port on carb at idle of 800 rpm. The idle screws are turned out only 1 turn. The accel pump squirts fine. I will see what the metering rods do during start. I do know that at idle they are pulled dowm tight. I have tried start w throttle closed and partly open; neither made difference with pcv hooked up. I will try different pcv and also see what vacuum does during start. Thanks to you and others that replyed.
Did you ever find the magic PCV?
