So I recently purchased a mr brog churchwarden nr 14, and not a week after buying it I was taking the stem off to do a deep clean when the tennon broke. I emailed the eBay seller and he sent me a new stem for free. However, I was just putting in the stem and it doesn't quite fit. It's so tight that I wasn't able to get the stem in all the way, and it's now stuck in the shank in an awkward position. I really like the pipe so any advice would be greatly appreciated.
