Just picked up a pretty nice mid 50's Titan 30 saw for dirt cheap. From what I've read it's basically a rebranded McCulloch, but that's about all the info I can find. I cleaned the points and it has a nice hot spark, but I need to get some new diaphragms for the carb before I can run it. Does anyone know where I can get these diaphragms or get them made? The carb is a Tillotson H5AX. I also need to know the fuel mix I should use when I get it going. Aside from that it look like it'll just need a couple fuel lines and a new filter in the tank!
