77 360 tuning help please

Check the timing first. Then pull the top off that crappy Eddy carb, check the floats and make sure there is no crap in the bowls rust dirt etc plugging the needle and seat. Choke should be closed at cold startup and opens progressively when the engine warms up. Popping through the carb could be a lean condition, or the camshaft has a worn lobe on it.
