I saw on another site that when the throttle is closed (key on but not started) it should be set at .45V but they had a problem and ended up with a setting at .32V to make it run right.

Mine was at .28V when I checked so I set it at .40V. It idles great now but bogs a little out of the hole. I'm going to try it at .45V next to see if it makes any difference.
