90 is a bit low for these. They like over 100 psi generally. Hows your head gasket? I have the same issue with my ’75. It has 105 psi, new carb kit, new head gasket, new ignition and still wont idle right down in tank or on boat. I personally think mine maybe the lowing bearing seal maybe toast, could possibly be the same issue for you?
