I still have to go back and try to get the 40 with the EZ carb tuned properly. I didn't try long enough to get it to idle right.
I made an adapter for the C-case .40s to fit a TT .46 muffler to it. I can use the TT muffler or the .46 Jettstream muffler that fits the TT engine. Depending on weight, I will use either. The Jett muffler is lighter than the stock TT muffler. The small Fox muffler I have is louder than the Jett muffler.
