After looking into it more, it would appear the Juki walking foot is just a piece a crap that nobody likes. Even Juki recalled it and the "improved" one is still lacking in functional performance.
Solution: Janome walking foot. Though 2x the price, it is a heavy duty high shank attachment that appears to be better in both function and speed.
Maybe that means I can "full throttle" it... with the right attachment ;-)
