An engine requires gas and spark to fire but it also requires compression and timing. If it has gas and spark, I would check the compression...should be over 100 to run good. If it has good compression then I would check to see if the spark occurs when the compression does. If it doesn't then you probably have a sheared key on the flywheel.
