I have an old Super Tiger .60/.61 from the 70's and the carb is shot. It is in a sport plane/pleasure flyer. I have purchased a new Perry carburetor for it and was wondering if I need to use a pump on it. I am not planning to compete with it but would like the best performance possible. I have not used a pump before and would like to know what kind of performance to expect with and without the pump. It is one of the finest running engines I have ever owned. I want to get it back to the good old days. Any thoughts?
