So I picked up a free BM23 this weekend off of CL. Seems to be in descent shape. The guy was trying to get it to work and had the wiring all srewed up. Once I fixed that, It fires up fine but didn't cool. Found a hole in the evaporator so I brazed it and have to fill the system (I'm an auto tech and it uses r134, so I'm fine there). My question is how many cornys can I fit in this thing? I did a search and it seems to be 4, but how much room is in there with four? I need to replace the tower (cracked and no spigot) and I'm undecided on a dual or triple tap. If I can fit four kegs, I'm thinking a triple tap and room to carb the fourth keg. If it is real tight in there with four kegs, I may just lean toward the double tap. opinions and/or pictures would be great. thanks!
