You say '...how can I get it running again'. A little history please. Is this a new motor to you?? When was the last time you had it running? Will it briefly run if you spray fuel/oil mix directly into the carb throat?? Give us a little more info so we can help you.

Hi, Nigel.<br /><br />Go to FAQ and do the troubleshooting in "Outboard Wont Start".<br /><br />Let us know what you find.<br /><br />Good luck. :)

Apparently it was running?<br /><br />Do as Xcusme suggests...squirt some fuel mix down the throat of the carb and see if she fires.<br /><br />If she fires, you have a fuel flow problem. Does the primer bulb pump up snug?<br /><br />If she justs pops, pop the flywheel and give the points and coils a look. A pop every now and then usually indicates a spark problem. Check the gaps are set at .020. Coils in good condition with no cracks showing? Spark plugs good and gaps at .030? <br /><br />When was the last time you had the engine tuned up?
