Hello. I recently got my first typewriter from GoodWill and I'm having an issue with it. It's a 1957 Remington Super Riter serial J27759970 with the wide 20" carriage. The carriage sometimes gets stuck while typing, most of the time it's either while all the way to the left of the page with margins set (seems to work fine if I go all the way to the end without the margin tabs)  or about mid-way down the page. Sometimes hitting tab will make it move again and then can continue typing normally, other times the manual carriage levers are pressed to make it move. I cleaned the rails with mineral spirits earlier and that seemed to at least remove the mid-way stuck point for a little bit but it came back. I don't see any noticeable damage, but I'm not sure what I need to be looking for in particular. If needed I can take  video of what's going on. Any help would be greatly appreciated. Thanks.
