I had the same problem on an organette, with cross-talk between tracks.
I filled each passage with shellac, sealing the exit, and blew gently
down the passage to encourage the shellac to fill the sideways leak.
I then drained the passage and blew through to ensure that the passage
was clear.

I carried out this process for all passages and then left it for a few
days to dry.  If the leaks aren't fully sealed, do it again.
