Buubba,
One thing nobody mentioned is removal of the spring clip on the base of plug cap. It takes one heck of a lot of force to seat the cap with the clip still on and very difficult to remove the cap when clip is seated. The first thing I do with all spark plug caps is replace the clip with a silicone rubber ring. Holds securely enough but is easy to install and remove.
I saw that you mentioned that the plug cap is seated but try removing the clip and reinstall. Just a thought. The idea is to eliminate all obvious things first before going into more complex investigation
Hi Matt, you are clearly one of the more knowledgeable people on here, however I fail to see how if he is useing the stock plug cap pushed passed the hex head, how will that not be makeing a ground?
The plug cap, as far as I know, is meant to be an electrical connection between it and the spark plug hex, as long as there is a solid connection there (with the backup of the spring) I don't see how this could cause a problem.
Granted your alternative may be more user friendly.
Matt, I'm not trying to aggrevate you, just don't understand the logic of how your alternative could fix this.
