Most of the newer engines are leaned out for emissions with limit caps on the mixture screws. If you alter the limiter cap so that you can adjust the idle mixture that the engine REALLY likes, it'll start right up at low idle. The reason that they won't start, except with the choke on is because they are limited to a too lean condition at idle.
