Sorry to bring this back from the dead, one more question...
I purchased the choke stove tube kit for my engine and am about to hook it up to the car. The original set up actually had one hard line from the side of the carb (threaded) down to the exhaust manifold and an aditional rubber line that connects to the carb via a nipple, turns into a metal line that also connects to the manifold. I know that the kit I purchased replaces the hard line and attaches to the threaded end at the carb but what do I do about the nipple at the carb? Is this simply blocked off? Is it left open? If left open is it drawing in un-filtered air?
Sorry for the newb questions?!
