This is a photo of the bottom of my Tappet plate. Anyone know what the A slot is supposed to be for?
I did a simple test with the ribber - I twirled it without needles - and it would snag. So I swapped out my dial for a different one - thinking that I had a problem with either the dial or the tappet plate.
I think I have a problem with both.
Looking at the tappet plate and feeling for any bumps, this is what I found (look at the tip)
There's some damage on the edge. When I put the 36 slot dial back and turned it around, I found a ding in the area where it snags - and guess what - it lines up with the damage on the tappet plate.
Now I decided to look at my 30 slot dial. WOW! Lots of dings in the same general area.
So, my question is would I be able to save these parts by filing down the areas so the dial/tappet spin smoothly or should I just invest in new parts? Of course I'm leaning towards filing the damage down.
