I have a couple of questions about my new Brison 2.4. I want to put a smoke system in my Waco and the Brison website says that it is already tapped for smoke. Now this is my first gas engine and I am really unsure about where things are. Where is the tap for the smoke? Does that mean I can use the standard brison muffler that came with it if I just go and buy a pump? Also, what kind of smoke system should I use? This will also be the first time I am using smoke. I have been looking up on the Bisson mufflers website as well and I cannot figuer out which mufflers have smoke or not even. These are some really stupid questions, but I really do not know what to do.
