Chris you are right and wrong about two things. First you are right about retarding the timing 2 degrees for every 50shot. But you are wrong about timing a motor by ear. If your around alot of competition engines enough you will learn that you can time a car by ear if you know what your listening for. It's especially easy if your car is loud. A loud car is easy to set timing by ear because you can hear what the motor is doing. I set mine by ear and when i put a timing light on it..it was DEAD ON. So you can definately time one by ear. Just make sure you know what your doing.
