Re: Several KM Questions
KM's are hand made. So every KM needs to be custom fitted a bit. I am sure you can go to a local hardware store and get the right fittings you need. But if you arent you can follow what jvminner suggest.
For cooler smoke? I am not a KM expert, but i would think it would be because the KM has a wider down stem then a MYA. I am going to assume the travel "time" of the smoke is not going to change. So there is more smoke and the time spent in the ice water is not enough time to cool it down.
I suggest get a Diffuser. It breaks the smoke into smaller particles, which will cool faster because there is more surface area.
