Thanks, it's working as good as it's going to I think. I started out having little movement at the wipers at all.
I've turned that little bar every direction I can think of and finally got 3/4 of the window wiped. Maybe that's all this one will do.
Acts like the lever the transmission arms hooks to with the spring clip is a shy short and not pulling the arms enough.
Since it has new glass on it I've been using clothes pins on the nub sticking through the cowl to see how much swing it had rather than running the wipers on the windshield.
I'm gonna ask the manufacturer if they have any tips.
