Jim, I think I was imagining this backwards, as I had thought the direction of rotation was the opposite of what you're stating, and thus that the increased tension on the pad from the pull of the exhaust cam would be responsible for advancing intake timing. This doesn't make much sense, though, since the tensioner on
any chain should be on the return side, where it doesn't need to deflect the chain at its maximum load.
What's more, I don't think the chain's centripetal force
would depress the pad, since all the angular momentum developed at the sprockets would allow the top tensioner pad to move up as the chain attempted to spin in a circle, not push it down.
It may be that this is a sham modification, unless anyone has any other ideas?
