No Spark - I'm Heading For The Rafters With a Rope

Had the same problem last week on my Dart the plug that goes into the orange box was not all the way in. Pull the plug all the way out then make sure you push all the way in until it snaps. I tried for 4 hours to get spark to my motor I did everything including rebuilding the dist. always ends up being a stupid little thing like a plug. Won't hurt give it a try.
