Runs good but there is a tapping noise comming from behind the pushrod cover. I removed the valve cover and isolated the noise to a pushrod that sometimes moves a little to side and is smacking the pushrod cover. I adjusted the gap for that pushrod/rocker but no joy. I am able to stop the rod from moving to the side by holding a screw driver against it. Tonight I will be taking the pushrod cover off to see whats-up. Any thoughts about what I'll find? Gary
