I just bought a alum. narrow bore D burke whistle. My problem: when i go to clear the spit out, it seeps through the mouth peice. the only thing that i can think of is that the plastic shrunk and its not a air tight seal due to the climate changes it endured. Any ideas how to fix this.
Would it not be a good idea to speak to Michael first?
Talk to Mike.
same thing with my burke. I used superglue in that crack of the mouthpiece, filed it down nicely. works just fine, but needs repeating. I don’t play my burke too often anymore, so i’m ok with that now, but it was quite annoying.
I believe I noticed this on my Burke also. I felt that I was blowing out very hard to clear the whistle and the amount of spit that showed in the seams was quite small. I didn’t feel it was a problem myself. Spit didn’t show up in the crack during regular playing or when I blew it out more gently. But I am not an experienced player.
I found it fairly annoying, because while playing, my chin got wet. not very comfy…
Acetal does expand and contract a bit with changes in temperature, and no glue will stick to it very well.
If moisture ever finds a crack, it can seep back through the mouthpiece and leak out… though there should only be a tiny amount if the fipple plug is properly fitted.
I’ve experienced minor leakage with Burkes, and with my own whistles… but never enough to consider it a problem.
The mouthpiece assembly is held together with a pin, since glueing isn’t an option… it’s just the nature of the material and mouthpiece design to possibly leak a little bit around the fipple plug.
I’ve noticed that the problem usually clears itself up after a while… particles are carried into the cracks by the seeping condensation, and eventually form a seal.
you mean like chips and peanuts? 
talk about revolting posts…
JOSEPH!!
Grow a nice, thick beard (see my avatar). It’ll still get wet, but you won’t notice it. (But if you kiss someone, she might. 
)
I think you should talk to Michael Burke about this before trying anything yourself.
I have two Burkes and neither has ever had this problem.

I have 5 Burkes and I never had this problem with them or any other whistles I’v had.

Happens on mine also…never enough to bother me, but its definitely there.
Oh, no, dear! It’s not that bad! I don’t think he meant chips and peanuts. Peanuts would be too clumpy!
I think it’s more likely to be the minerals in saliva along with some bacterial colonization.
And maybe some fungus.
I had the same problem with my Burke narrow bore and I agree with raindog.
Dang, Darwin!
I always wondered what your avatar was?!?!?
Oooooo
In the beginning I thought it was the back of his head, showing a little bald spot, reminding of the scene in Lotr, part three, the old Bilbo Baggins, as he walks to the ship, you see him from behind, with his hair, ‘just’ like darwins.
Oh dear, that would be strange. I never had anything close to that.
Well, I hope you wash it afterwards! I think things could start growing in there. Eeeeew!
