I have what I believe is a 1989 30 hp evinrude (drk blue), I see a post from last year that is almost exactly what my motor does, at idle it runs perfect<br />but when I take off the engine starts missing at about half throttle, all the waty to full , but if I back off some it will run great and the miss will dissappear. I have checked all the obvious things but am not sure what to do next.<br />To my knowledge the motor has never been rebuilt or<br />repaired, could the fuel tank/line be bad? how about a carb rebuild, ignition???<br /><br />Help!!!
