Hi Darryl
I think that I would remove the entire assembley by disconecting the rods and dropping out the plate, its possable that one of the clevis arms may be bent a little and allowing the leading edge to contact the front edge of the cam area,if you get the entire plate out and on the bench you can then see how it all works and also see what is causing it to bind, I know that it is a bugger of a job but if you do it right you only have to do it once, I have had this sort of problem a couple of times over the last thirty years,and it is easy to fix if you have the cam plate and clevis rods out all in one piece, I will say that I have no knowledge of the Canadian carriers, I have only ever restored Australian ones,but quite a few of them
Good luck Regards Ron
