That wire on the tappet cover has got to be a ground wire for something. It certainly doesn't operate anything under that cover. You need to trace it back and see what it's connected to. It's not standard equipment as far as I've ever seen on an AVL. The valve adjustment should be the same as the video.Bare
He's not seeing a "wire" wire. I think what he's looking at is the decompressor cable. If you don't fool with the adjustments, you just take the cover off & put it back. It all just falls back in place.
That statement put me off a little, we are adjusting the valves as they are tight. Since we are adjusting, is there going to be an issue with putting the plate back on?
