It is going on a 235. And the copper hose is rapping around the exhaust. I ran the hose to the air cleaner just for clean air but I could run it else were as well. Some people say it was ran from the exhaust at one point??? I know the carb has a vacuum but not sure were the air comes from.
Here is a new pic. Would this work better?
