This is not probably a machine that will do very well on auto interiors, because most machines have 10 1/2" of space between the needle and the upright. The only Singer part numbers I can find for your machine's foot is 208597, and 208598, and they are not a presser foot. I don't know if they ever made a standard presser foot or a welt foot for this machine. Here's the part list for the machine: http://parts.singerco.com/IPpartCharts/151W2.pdf
I thought you had a 111W151, which would have been fine, not a 151W2.
Thanks Dan for checking into this. After workin on it for hours and taking the presser bar assembly apart I think somehow I got the timing of the presser foot and the vibrator foot off. Presser foot comes up when it should, but vibrator foot lever lifts as needle lifts. After reading the instructions in that link about 500 times, it looks like lowering the depth of the presser foot makes the vibrator foot raise higher. Which makes since. Because I can slightly raise the presser bar (which essentially lets the presser foot have further travel downward) and the vibrator foot will go up and down as it should with the needle movement. I boogered up the screw in the back that locks the adjustment on the presser bar (flat head screw). So Im gonna see if I can find something compatible locally tomorrow.
I have to check my part numbers against 111w151 part numbers a lot just to find parts. Alot of 111w parts do interchange, and alot do not. I will update tomorrow and let you know how it turns out. Otherwise, Im gonna sell it to the local sewing shop and look for something else. Preferably with reverse.
