Vibration right off idle

Ever notice how the carb is always level, but the drivetrain is tilted down in the back? And the manifold is angled about 3 degrees? You tilt the motor/trans down in the back about 3 degrees, and the pinion up 3 degrees. That article was written by a person who really doesn't understand driveshaft angles. Read his last post about Sunbeam Tigers. Driveshafts don't know the angles of the two units they are connecting, so up, down, left, right; don't matter to a driveshaft; only the overall angle; measured from any perspective.
