Did you remove the flywheel? Or just replaced the coil? Coil needs to be .010 inch from the flywheel surface when mounted. The magnet and the coil is all that make the spark on a Briggs engine. If still no spark, remove the kill wire on the coil and check for spark again, If you now have spark , the kill circuit is shorting out the spark.
