I wonder if popping a filter in the large hole might help. You could probably open up the hole on the stem—this could end up being a fun salvage job to make the pipe usable.Just keeping it simple, Mac Baren Navy Flake in The Savinelli. The free pipe I picked up from that guy is... well, seems like a home-made job to me. The draught hole is gigantic, almost as big as the hole for the tenon, to clean it, you need a cotton swab, and even then, you have to swish it a bit as it's an extremely loose fit even with that all the way to the bowl, and the cheap stem on it will not pass a pipe cleaner at the bit end. It may well end up in the garbage.
