Hi , I am helping my brother get a 77 HiLux running better. I re connected all the smog vacuum lines per the faded hood sticker. It starts and runs better now, but there are some extra vacuum ports on the carb that are not on the sticker. Notably the two for the çhoke breaker and opener. Where do they connect? There's is one port below the carb that is twinned, one is for a smog line, the other we called. Is that for one of them?

Also there is a 3/8 pipe sticking out the front of the carb, there is no hose connected to it. What should be connected to that?

Thanks for any help.
