First, I apologize for my English - it is not my mother's tongue.. <br />My Tohatsu 6hp four stroke sucked water and dirt from the tank (ran out of fuel.. my fault..); since then it dies often on very low revolutions (on minimum gas - while in gear - happens mainly in the harbour!). I had it serviced (carburator cleaned with compressed air and chemically, spark plugs replaced, minimum gas adjusted, etc.) with little success. <br />Minimum gas is even too high now, so that does not help. It never dies in idle. Looks like an ignition spark would be missing and the motor stucks.<br />It looks as if it would need the setting for minimum air flow (which it does not have) together with the minimum gas. What else can I do?<br />This is my last try - I am even thinking of selling it.. <br />Hope you got the problem. Thanks.
