Removing my old exhaust system, I had a smaller tube coming off the downtube. The smaller tube bends toward the passenger side and up to what appears to be some sort of valve. The valve partitions part of the exhaust gas back to the air intake. The tube I took off had about 10 holes in it, so I know it was not working properly.
I am guessing its purpose was to recirculate unburned exhaust back through the carb in hopes that it would burn on its second trip through the engine. Doesn't make a lot of sense. Anyway, do I need it? What is its correct name if I were to get a replacement? Or should I just weld the tap on the new downtube shut (no emissions testing here).
