Jillaine, I have a 1909 Singer 66-1 with brown lotus decals. I took the motor off and put it in treadle, which is where it originally lived. It is so much happier. I ran into some stubborn screws, but the handwheel knob turned easily. Hope you get someone to help you get it loose. Be careful, though, with taking stuff off. If you get it back on wrong, it can cause all kinds of problems.
When you look at the bottom of the machine, does it look reasonably clean, or is it really gunked up? That's including looking up the column with a flashlight. If it's reasonable clean, you can just do a cleaning by MUV's videos instead of taking it all apart. Only the extremely frozen/gunked up machines need the whole clean up by Billy's method. It's a lot of work that is not entirely necessary if the machine is relatively free of stiff gunk. Just saying.....
