    the optimal a/f ratio is 14.7: 1 that is called stoichiometric the problem it only works when the eng is operated at a constant rpm and load and temp. like in a stationary set up like a pump but automotive eng have constantly changing conditions under heavy load the mixture needs to be about 12: 1 or 12.5 :1 the key thing to remember is load you would do well to tun a vacuum gage inside the car a large one like 4in leave it hooked up wile driving do that for a month or 2 you will learn more about carburation than you can learn at any school play with compare the mixture and load and rpm and you can dial it in and have fun and learn a lot......ted
