    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.
    Light travels faster than sound. This is why some people appear bright until you hear them speak.

        Apparently it was running?Do as Xcusme suggests...squirt some fuel mix down the throat of the carb and see if she fires.If she fires, you have a fuel flow problem. Does the primer bulb pump up snug?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? When was the last time you had the engine tuned up?
        When in doubt...use the manual
