Is this the 4 cylinder motor? If it is you have a 16 amp charging system. If it is the 4 cylinder you never spin them past 5250 rpm. If it is the v6 or 3 cylinder opti motor disregard.
Did you put the correct Jets in it? The correct yr Carbs? All 70 carbs aren't the same. Wrong Gasket on top if it's plastic top? or is it a metal carb? Primer leaking?
