I was wondering what the base rpm in neutral is for a 40 HP honda, and whether adjusting the base idle screw has any effect on parts such as the carburettor balancing. <br /><br />Also what effect does a low idle rpm have on the running / starting of these Hondas. I currently have a little Honda tacho that clips onto a sdpark plug lead. It ias reading 800 rpm in gear and about 900 in neutral.
