I'm trying to get the carriage off of my Rem Noiseless 10. Something is binding in the track, probably gunk, there was also a squeak which I pulled my hair out trying to find, it turned out to be the spring drum. A small amount of oil fixed that. But the carriage is still binding enough to cause problems. I haven't had this thing apart to do any cleaning, in fact it's pretty dirty inside, though other than the carriage problems it works great. I don't want to take it to pieces, not until I have another working machine, then I'll give it a complete cleaning. Now I am only addressing problems as I find them, I can't have this thing out of service too long. THE CARRIAGE: I am following the instructions in my service manual, I'm at the step where I need to remove Carriage Retainer Plate 10-40880, but I can't find it in the diagrams. What's a Carriage Retainer plate look like? I did do some googling before I put up this post but didn't find anything
