I have a Holley Blue Going Through a Aeromotive Adjustable Fuel Pressure Regulator set at 7 lb's , I just looked at the Bowl Sight Glasses This morning and they are at the same level (Middle Hash Mark) as last night, The Plugs are Autolite 3924's gapped at .060 this isn't an every day problem just maybe once a week and every day it will sorta miss kinda like a weak fire then after it warms up it clears up and runs great..!! been then just some times the plug remains dead and it won't ever clear up.
