I just received my replacement part for my dremel scroll saw 1672, I replaced the sping because it was broken and now trying to replace the guide pin and not quite sure if it is correct. It doesn't seem to function right once I put it in, not quite sure if I am doing it right, would appreciate some guidance if any has some advice please free to get back to me. I really love my saw and have missed it for quite some time because of the broken spring. I am very anxious to get back to my crafting. Thanks for any help. Nadra
