It's just now past the break in point of 1200 miles and I have only opened it up a coupe of times.
To me, it doesn't feel like the spring or tension in it. I feel like it is a bend in a push rod, or possible the interaction between a bearing, like it's sticking.
I do appreciate all the input.
Will update when or if root cause is found.
Thanks
