I have a suntour mountech RD on my 1983 Miyata 610. It keeps throwing the chain off the lowest gear and it gets caught in between my freewheel (5 speed 13-32) and the plastic disc on the wheel. I have suntour friction bar-end shifters. I have had this issue looked at by two bike stores, and they will charge me $10 to do some quick simple tightening of a piece of the derailleur and it will work fine... for about 2 weeks and then it starts happening again. I feel like if I just understood the mechanics of it even a little bit I could fix the issue, but I feel like at this point I'll just have to buy a new derailleur? It's a shame because otherwise the shifting is flawlessly smooth. Any advice?

Sounds like you just need to adjust the low limit screw on the rear derailleur, although I don't know why you would be repeatedly having the problem if the bike shop(s) adjusted it correctly. Here's an excellent guide to adjusting a rear derailleur, I'd recommend reading through the whole thing, you'll gain a good understanding of how the RD works, and how to make all the adjustments:

my fault - sorry guys
I just finished reading the sticky.
Too bad they can't show it in the list with flashing neon colors. :D I probably wouldn't have noticed it either.
