Looking good. Has he fired it up yet?
I don't think so. I suspect it's the first test assembly. We've talked a little about it. Full flush of everything, and new battery come first. I do see a car battery on the trailer, so maybe he fired up the ignition to see the ODO, etc. He's asked about the cam chain tensioner. I have never replaced it but the mileage didn't call for it yet and I don't think these were in the recall. I would suspect he may do it before final assembly (while it's easy to get there).
I also suspect he'll pop his head up when he takes a breath.
