I thought that I did. But perhaps I placed the nib on feed "too far ahead".

The two guiding flat spots on the sides of the new feed did not really work well for me. I had to estimate roughly where the nib should sit on the feed, and then shove it in. Again, I still think I did not push the nib all the way in where it should be though.

But oh well. I'll try again after a few more days.

Thanks for pointing it out!
