So, how hard is it to get a belt properly installed in this situation? I'm a willing learner! I don't want to give up now. Never sought out this machine, but now that I've got her, I'm determined to bring her back to working order. Found the s/n. It's an old version of the 328k as it does not have a switch for the light; just is on whenever machine is plugged in. Oh, and it does have one cam inside it....the zz cam! So, if I get a belt installed, I'll have the straight & zz stitches.
