Keep at it. It took me a lot of work and patience and wiggling this and that. I got it to work great. Then I found a 301 and got that working. Then lost all mojo and then we moved and I haven't much worked with the vintage machines. Then a PQ 1500 practically fell into my lap and I am quite enamored with it so haven't messed with the vintages in a long time. I think if I get the 401 out I will have to start over!!
