My Yanmar 3GM30 is difficult to start. It turns over erratically and then I got it to go by turning it over and over and eventually it started, erratic at first asnd then it then ran well. I left it running, no problem. Over the next few hours it started instantly each time I tried, starting and running smoothly. Next day, back to square one. There is no smoke, batteries are charged. WD40 seemed to help but not much. Any suggestions?
