    When i go to start the engine over it just turns over and over but doesnt fire. I drove it with a load of hay, it ran fine but the next day when i went to fire it up, nothing. It has air and gas but a weak spark, ive replaced the distributor cap, rotor, coil, ingnition control modual, pick up coil is good and the plugs. And if i tested it right, contintuity is okay. Im kinda stumped at this point. Check for a spark and get a orange colored spark. I know its supposed to be blue. Any ideas of what could be the problem? Please help me out!

    I'd suspect low battery voltage while cranking.
